    obd-II software

    Hello,
    My check engine light has been on for a few weeks now, and when I brought my truck into GMC (I have a 2003 Yukon) they would not even hook it up to diagnose the problem, because I have an aftermarket Volant cold air intake in it. I believe my problems do in fact stem from this intake, but now I need to diagnose my own problems. A friend of mine has the OBDII plug and cable, but he said I would need the software so he can check my truck. Can I download free software somewhere for my truck, or at least can someone suggest a specific software that I should buy. I'm sorry, but I have never done this before, and I tried to research just the software, and have had some difficulties. Perhaps I'm not typing in the correct keywords, because I really know nothing about this subject. Thank you for any help!!

    thats a load of crap!!!
    That shop should have a least offered to pull the codes for a price. pulling codes with a good ODB scan tools takes all of about 1 min... damn I hate ****ty shops that give the rest of the good ones a bad name!!!!

    sorry about the rant, I have not jumped into the pc/odb-II stuff yet so I have no idea about the free software.

    If it become too much of a hassle to get the pc thing going you may just go to another shop and tell them "tell me what codes I have" it may cost around $30.00 depending on what their hr labor rate is.

    Usually the software you need depends on the cable you have, and you need the right cable for your car's protocol (VPW for GM). You can buy your own cable and software for pretty cheap (certainly less than one hour of mechanic's time). Here is a list but you can for OBDII and VPW (your protocol) for more.

    Sometime's you can read out codes by just turning your ignition on/off in a certain sequence and reading the number of times your CEL flashes, but this is a pain.

    Look at the MAGNUSON-MOSS act. They can't do that. It's illegal. Now if the problem is your intake, they can indeed charge you for service, but they can't refuse to service your car. They have to prove it's the mod.

    That being said, why don't you just go to the local Autozone (if you have them in NY) and they'll scan it for nothing.

    OBDII software title

    Hey,

    Give this one a shot? It's free and reads any COM port. Whether it'll work with your cable or not, who knows?

    http://www.obd-2.com

    Has the most in-depth vehicle sets I've seen on a free title, and better than most paid.
    There's nothing you can't do, so don't be discouraged just because no one else's done it.
