Automakers to Make Diagnostic Codes Available 185

Rubbersoul writes "As reported on /. a few months ago independent auto repair shops are a bit tense about not having access to car computer diagnostic codes. Well it seems that now the auto makers will share these codes after all. According to an article at CNN the codes will be available to all professional mechanics as well as amateurs working out of their garage at home. Good to see the auto makers came around on this one, even if it did take Congress to help a bit."

      Diagnostic codes are read only. They will not be releasing any modification codes I am willing to bet.

    • uhhh, what you get with a commercial tool is almost always the international standard codes, occasionally manufacturer-specific drivetrain codes. with very few ($2000 and up range) exceptions do you get the "chassis codes" for traction enhancement controls, transmission/engine crosstalk codes, and so on.

      you still are not going to get them free, but they will be availiable in updates some day before we all die to professional test readers.

      presumably this will also include the equivalent to the "mode 4" international code for the wacko ones. "mode 4" is also known as "reset," turns out the $$$ light on the dash.

    This is a pretty big deal since it's pretty tough to figure out what's going on on computer controlled engines otherwise.

    This is a bigger deal because it means that people publishing the codes will no longer face the prospect of being sued for posting it and means that, in this case at least, the auto makers (with pressure from congress) decided that public good out weighed copyright law.

      Actually the auto makers have always had much incentive to release the codes. But their relationship with the dealerships has kept them from doing that. The dealerships of course make LOTS of money from diagnostics, not the manufacturers.

      But the dealerships start to be at opposition with the manufacturers when warranty claims are made. Perhaps they got too much opposition and sowered the OEMs a bit too much!?
  • Under the agreement signed by the Automotive Service Association, the Alliance of Automobile Manufacturers and the Association of International Automobile Manufacturers, the automakers agree to make the service information available on the Internet by Aug. 31 at a "reasonable price."

    Which means that private mechanics will charge more to analyze the codes since they have to pay a "reasonable price" which negates:

    Some automakers felt more comfortable giving the information to their dealerships, which must keep the data confidential under franchise contracts. That often meant higher costs to consumers, since dealer labor rates tend to run $10 to $20 per hour higher than independent shops, according to AAA.

I'm not against corporations coming to town on a political level, but it stinks to drive out in the country and seeing mom'n'pop stores taken over. And with all of the computer chips and advanced parts requiring really expensive tools to fix, it's nice to see something to go against that trend and empower the small guys again ;)

      • Actually, if you buy the OBDII reader and a factory service manual you have enough information to understand what the code is and how to fix it. You can buy factory service manuals from www.helminc.com. These two resources are indespensible for a DIY mechanic.
    • SAE defind trouble codes are only defined to mean something within a certain range. There are manufacturer specific trouble codes that they can make mean whatever they want. Those are the codes that we don't know the definition of.
    • OBD-I and OBD-II are the Federally mandated codes that auto manufacturer must make available to any standard reader; this is mostly for emissions-related fault codes, and doesn't cover other components of the car that may not have a direct effect on emissions. The point is that an owner may have some mechanical or electrical problem with their car, which might not be diagnosable by an independent shop due to proprietary codes, and the car would then need to be taken to a dealer to make the diagnosis and repair.

    These are Diag Codes not Source Code. These will not give you information to put Linux on your car. They give information like Code 2453 Means Sencor 4 is malfunctioning. So opening the code help the machanics not the hacker. They are not saying how the Onboad computer is working just giving you the information on what is wrong.

    As someone who works in the industry on the engineering side I am very familiar with their "codes."

    The codes will be USELESS to a mechanic. A mechanic needs a "TOOL." A mechanic is not a programmer or engineer. He will still pay $300 for the tool to read the codes. he will still pay $100 per 'module' for each car's codes he wants to read.

    He can do that now. So the hope is that more tools will be developed and that will bring the cost of the tools down.

    Don't confuse this with any ability to modify anything. These will be read only idiot codes like "o2 is out of range" or "Low Voltage."

    It still takes a good mechanic to find the problem and often, VERY DAMN OFTEN, the codes are simply misleading the mechanic when his nose and ears have already given him the answer.

Even if you have the tool and plug it into your car's computer it only spits out an error number and a little extra information. What does it mean? No one knows....except for the car makers who want to charge you money for the manual.

      This is the same stuff Free Software Philosophy seeks to fight: closed systems that take rights away from the user. You bought the car....why can't you figure out what is wrong with it on your own if you choose to do so? Why do automakers want to keep your property a secret from you?
    • you also need the diagnostic trees for the particular auto system(s) that you are trying to fix. you see issues, you pull codes, you work down the diagnostic tree from the factory manual, alldata, whatever... try a couple other tests as prompted by the tree... and > THEN as if by magic, you get down to one or two parts, adjustments, or lame excuses to lay on the customer that solve the particular issue.

      if you can't hear, if you can't see, if you are colorblind and chasing wiring, you have some handicaps in the way of fixing a car. same for not having the diag codes from the modules.

      none of this has anything to do with reverse-engineering the real-time process code in any of the modules, or using the airbag controller as a circumvention device so you can play DVDs over the heads-up display. it is the equivalent of self-diagnosing system outputs like S.M.A.R.T on hard disks.

      As someone who works in the industry on the fleet mechanic side I have to disagree.

      The OBD-II codes have been around and they are helpful for the most part. What has been needed are the non-standard manufacturer specific codes.

      I wish I could purchase a good scan tool that would work on the major brands for $300. With software, leads, and adapters for domestic only I think our Mastertech package was over $2,800. That's domestic only, no imports, and it is never current. I'm just now getting updated for 2002 model year vehicles.

      You are correct that it still takes a good mechanic to find the problem. A good mechanic stays current with his training. Todays mechanic is not a programmer, but he is a technician.

      Using the scan tool to read diagnostic codes won't tell the mechanic exactly where the problem is. He has to know the systems well enough to understand what the on board computer is telling him. The ability to read the real time data stream is important too, maybe even more important than knowing waht the diagnostic codes mean.

      It is important to understand how the on board computer arrived at the diagnostic code. You have to know what test is run, how it is run, and what the conditions for the test are. If you don't have that information then you are correct, the codes will be misleading.

Autotap is not just for Trouble Codes, you can use it to monitor 1000's of parameters in Real time!! from how much air/fuel your car consuming, how far you have your throttle down, what gear are you in, what's your temptures etc etc.

    Sometime friend who have Service Engine Soon light on their late model car I tap in and check out the code (Which cost $75 at the shop) so we'll get idea on the problem with the car before we take it to the shop.

    There are palm size code readers and scan tools also.

    This situation is like if you had a car and they kept the specs closed so that you couldn't figure out how to...

    ... wait -- no need for a car analogy on this topic.

    Never mind.

  • As an owner of "beater" cars, I can honestly tell you that those codes do not matter one bit, and are only there to get you ripped off by auto mechanics.

    My beat-up Chevy Celebrity has had that yellow "Service Engine Soon" light on for years, and it runs just fine.

    The whole thing is nothing but government waste, as there's a lot more pressing issues at hand than forcing companies to publish every single detail of their trade secrets.
    • Ugh, a celebrity. I don't think I could ever say mine used to "run fine". That car was total trash. Only after I got rid of it did I see the consumer reports that ranked cars on how many repairs they required on average, the Celebrity was #1 by far.
    • I had a Subaru with a chronic check engine light problem. Two mechanics (one operating out of the Subaru dealer and one non-dealer) told me that (on Subarus anyway) that quite often the vague "service engine" light indicates a failure in emissions control or some other non-critical part, and unless the failure is causing a loss of performance or your car to just plain not work, that quite often it's not worth worrying about. (And even with my failed emissions control systems I still passed all emissions testing with flying colors... so I think quite often the non-critical part that's failed is the light itself...)
    • This is very bad advice. Hopefully you don't work at a nuclear power plant.

      The "check engine" light is there to tell you that a sensor is malfunctioning/out of spec. Something IS wrong with your car and it will probably cost you more $$$ in the end. Just because a car "runs" doesn't mean that there are no problems. Often the sensor codes are triggered during specific events such as heavy acceleration/hot/cold engine that won't show up while idling so emmissions and other basic testing likely won't indicate any problems. Under some circumstances, the engine may even be operating under "open loop" which means that it is ignoring most sensor data and instead using factory established default values in order to keep running.

      Considerable fault-tolerant design goes into the computer control of modern engines. For safety reasons, they will continue running as best they can despite significant problems. (except over-heat conditions which could cause fire)

      By driving with an engine out of spec, you may quickly wear out your expensive catalytic converter... or worse. A car will most often pass state emmisions tests just so long as the catalytic converter is not used up. The garage could get true diagnostic readings at the O2 sensor, not at the tail pipe.

      The code may also indicate a transmission fault that may be eating away fuel economy and cause transmission overheating such as if the "torque-converter clutch" isn't locking properly.

      BTW, on most american cars, there is a "trick" to get the car to read back the fault code without an expensive scanner. These days, many parts stores such as "Advance Auto" will also read-out the codes for free.

      The government's role here is to reduce pollution and improve highway/vehicle safety. By giving more people access to the diagnostic information(most of which has been "hacked" already), it means that on average, cars will operate better since fewer problems will be ignored.

      • Don't just keep driving... also, flip a switch.

        The Chevy Sprint and Geo Metro and other Chevy cars of that vintage had a blinking "check engine" light, which would go on automatically as soon as you hit 30,000 miles, and each 30,000 miles, after that.

        This was a result of a single-pole, double throw switch in the odometer. There was also a single-pole double-throw switch inside the fuse area (below and two the left of the steering wheel). In other words, a standard two location three-way switch assembly.

        The "corrective" action for the blinky light was to bring the car into the dealer, pay them a lot of money for "scheduled maintenance", and whatever engine parts they happened to have an excess of in inventory in their parts department that month.

        And for them to toggle the position of the switch in the fuse holder, to turn off the blinky light until you'd gone another 30,000 miles.

        Hooray for blinky lights that get people to spend money at the dealer!

    • I had a friend who got screwed over by the State of Arizona who has decided to base their emissions testing for 96 or newer vehicles entirely on the car's computer.

      His "check engine" light had been on for quite a while. He had taken it to a mechanic to see what the problem was when it first came on. The mechanic said that code was for evaporative and the reason was that the gas cap wasn't on tight enough. Well, he cranked the gas cap tight from then on, but the light came right back on.

      He didn't give it anymore thought since he was tired of paying the mechanic $100 to "scan the codes". That is, until it came time for emissions inspection. My advice now, don't go to the emissions place if your "check engine" light is on, there is NO WAY you will pass, that's exactly what the tech's there told him. Anyway, disconnecting the battery for an hour or so clears the codes (at least for this car), so after he did that, he took the car back; rejected again, "sensor's aren't ready".

      To make a long story short(er), a few trips to the mechanic and emissions place later, he's passed and has a new evaporative "switch" (parts $17, labor $40). This, of course, is after several $100 "diagnostic" fees.

      So, watch out, some states have decided that they'd rather not test which cars are actually polluting beyond the regs, they'd rather screw over people whose cars are in spec.

      Yes, it is news. No, auto makers such as BMW and Volkswagen were not releasing the diagnostic codes. This made it impossible for non-dealer repair shops to diagnose a variety of problems on newer model cars.

      My father is the supervisor of the auto shop at the University of Maryland, Baltimore County, and he was very concerned about this, as they certainly don't want to have to outsource any repairs on their fleet. These days, much of the work in diagnosing car problems involves hooking up a computer to the car and asking the car's computer, "OK, what's not normal?". It's not quite that simple; you still have to know what you're doing in order to figure out what's wrong (not like a dialog box pops up and says, "Mass air flow sensor bad. Replace? Y/N).

      Anyway, I spoke to my father today to make sure he had seen this article, and he said that basically the auto makers have said, "We promise to release the specs if you don't pass a law saying we have to do so." He doesn't really trust them, but is hopeful, and will wait and see.

    I think in some systems you can get (and maybe set) your fuel-to-air ratio, which controls how rich your car is burning gas and to some extent power. Turbochargers are based on providing extra air flow allowing for more gas to also be mixed in.
    Even if you can't stat your car on the fly, it would be quite cool to have the onboard PC able to do something other than play Mp3's.

      We'll probably end up recording all the codes into a public mysql db that can be queried or integrated into the core code.

      This would allow the UI to display the EXACT problem ("Your 3rd spark plug from the left is firing oddly - please check") instead of just "check engine". Very good news indeed.

    OK, here's an idea. Since the diagnostic codes are available, how about an on-board computer that monitors and logs engine data: avg MPH, mileage, temperature, daily usage, etc. The data could be downloaded to a laptop via a USB port, analyzed, and archived.

    Imagine: you're doing the monthly check, and discover that your mileage has suddenly dropped 10%. Even before something goes wrong, you could take it to a garage and give them strong diagnostic data.

    When the time comes to sell the car, you can provide a day-to-day profile of the car's history: every oil change, fillup, and repair automatically logged. Real examples of winter vs summer and city vs. highway performance.

    Seems to me that the technology is already available, and some of the functions are already in place. All that really needs to be done is for someone to hack together an interface. Any takers?

    • actually obdII already does essentially this. the father of a teenage girl brought the 96 saturn that he bought her back to us screaming and threatening to sue. she had told him the car would randomly cut out while she was driving down the road. what she didn't tell him is that she was doing 110 miles an hour every time it happened (the pcm shuts the engine down at 110 miles). all we had to do was hook the car up to the techII service stall and pull the information out.
  • Our old Toronado had a touch screen in the dash. It took a 3-finger exercise to enter diagnostics mode, the GM version of ctrl-alt-del, but then you:
    1. had access to the engine diagnostics codes
    2. could override/modify some things (e.g. shut down one injector, select Canadian shift regime)
    3. had a summary screen that showed engine & transmission status
    4. let you access the body computer (e.g. heat, A/C).
    I had hoped that was the coming thing, but they charged too much for the touch screen. The dealership was forthcoming with info on the codes, or you could buy the service manual at a reasonable price.

    Too bad. A great car, still looked good, my wife loved it, I could work on it, but we couldn't get parts to keep it on the road any more.

  • I mean, my car is a lease. If there's any trouble whatsoever it goes back to the dealer for servicing. In fact, it's in their best interest not to fuck the car up since they have to cover repairs under warranty, and they have to buy the car back at the end of the lease. So long independent mechanic, I barely knew thee.

    Although I'd probably be mad if I tinkered with cars in the same way I tinkered with computers and didn't have the open source equivalent.

    • n fact, it's in their best interest not to fuck the car up since they have to cover repairs under warranty, and they have to buy the car back at the end of the lease.

      Huh? If they mess the car up and it lowers the value YOU are on the hook for that amount. They had a set buyback value and mileage in your lease, if it is worth less and/or has more mileage, YOU pay for that, not them.
  • I must fix my car, I must get free. In this computer is the key. My key.

    Once my car is fixed, there's no need for me to be here. Do you understand? I need the codes. I have to get inside my car's diagnostic mode. You have to tell me how...

    ...or you're going to die!

  • This is very good news indeed, even i haven't owned a single own car and i do not repair cars as a hobby nor as my job i have been couple times pissed off because automakers hide some info, not particularly with the diagnose codes but anyway for that i have been missing some information which has been needed, like schematics of wirings etc...
    also i know a lot of people which has been same problems, actually one of my friend had his car just staying on the parking lot unrepaired because he couldn't get the schematics to fix the problem, he had his car sitting there over 6months until he gave up and took it to professional hands, he had it waiting there like 2months so that everything else had been repaired before he gaveup...
  • Something tells me that knowing "Code 41 == No Airbag" isn't going to help a shyster mechanic steal airbags.


    Is my FUD-finder broken or am I missing something here?

  • This is also happening here in Europe now that the EU have provided a standard called EOBD for all newly-developed cars which is actually the OBD-2 system which has been available for some time.

    This months issue of Elektor Electronics [elektor-el...nics.co.uk] has full details on the interface, with next months issue presenting a do-it-yourself EOBD diagnosis adapter. They also do an OBD-2 to RS232 adapter for those geeks wanting to play using their laptop in true "The Fast 'n The Furious" style.
  • For Audi and VW owners, theres been a 'tool' and software (that runs on windows, but can use WINE under linux) called VAG-COM that is supposed to just plug into the diagnostic port and give you real time data from the ECU, I considered buying it...VAG-COM page [ross-tech.com]
  • I wonder if this includes motorcycles. As a specific example, BMW uses their own interface to access diagnostic information for their motorcycles. The data is encrypted, and is not readable by anythin other than their Moditec computer, which you can by form them for something like $5000.00. I have one of these bikes, and it is frustrating to know that I cannot properly diagnose my bike's woes without going to a dealer.
  • A few things to know.... These codes being released will not allow you to be able to program your car, you're not gonna have a GNUHonda, it's just gonna allow you to see what the problems are. It also does not mean that youre gonna be able to just go to a webpage and download a program and just be able to work on your car in your garage. what it does mean is still great though. take the Porsche Boxter for example, normally when one comes into the shop you need the Porsche diagnostic tool to be able to reset the computer, which costs $14,000 and only works on a specific model. The availability of these codes means that other companies will be making these tools, so instead of paying Porsche $14,000 you would pay Snap-On around $1,000-3.000.
  • There is an awful lot of ignorance in this thread. Check what the domestic and import manufacturers' actually agreed to (from http://www.asashop.org/legis/agreement.htm):
    Automobile manufacturers hereby commit to make available, by August 31, 2003, emission and non-emission-related service information, training information, and diagnostic tools in the same manner and to the same extent as specified by California Air Resources Board (CARB) regulations for emission-related systems and components. This means that 1) the same service and training information related to vehicle repair will be made available to independent repair shops either via the Internet, or in the same manner and extent as it is made available to franchised dealerships and 2) the same diagnostic tools related to vehicle repair that are made available to the franchised dealers will be made available to the independent repair shops. These will be made available at a reasonable price consistent with the guidelines provided in CARB regulations. The service and training information and manufacturer tools will be available to independent repair shops without the need for them to return to a franchised dealership (to the extent allowed by law).

    Do you understand? This is huge. Huge, huge. This is indeed the "opening" of the closed information source. It's as if MS agreed to open *all* proprietary informational resources (private KBs, training, diag tools, etc.) that were previously used only by their premier tech support reps.

    Now will most mechanics avail themselves of this? Heck no. Most don't know or care how to truly troubleshoot; there are easier ways to flag hours that don't involve trying to convince a skeptical customer that you're not ripping them off.

    But to those who love troubleshooting, this is manna from heaven. Take codes for example. An earlier poster said they were useless. If all you had was the description of the code, that's a correct statement.

    However, if you also knew the exact criteria the PCM needed to see before throwing a code (this knowledge will be one of the takeaways from this act), you could then use your understanding of the proprietary system (a second takeaway) to straightforwardly troubleshoot and fix it.

    Make sense? This is a hallmark day for savvy techs (or rather, August 31, 2003 will be <grin>).
