    Help. My printer died short term and I couldn't print a thread on how to disable the Service Engine Soon light. Now I can't find the thread. Anybody remember?

    Hey, I'm a "newbie" now [​IMG].

    Thanks for any help.

    laurie, i would agree that sometimes the check engine light comes on for a reason! if it came on do to a bad ground or crossed wire and you cant track it down then just unplug it.

    Why would you want to disable it ?? It stores error codes for you ( the computer does). You can reset all codes by disconnecting the battery for 5 minutes or so, but if its coming on, there's something amiss. Its simple to check the error codes, lemme know if you wanna know how.

    Thanks guys. That light is driving me nuts. It goes on after I've driving slow in downtown traffic, idling at a lot at lights, or cruising the shopping mall looking for that perfect parking space (gotta protect "Baby" ya know [​IMG]).

    My mechanic friend will be giving the truck an overhaul, but it may take a while to get to whatever is causing the problem.

    Any information on understanding codes is appreciated.

    Thanks all. BTW Very funny Behemoth! [​IMG]

    Codes: First find the diagnostic terminal as shown in figure 3-2 of the attached. Mine is located under the steering column. You'll need a short piece of wire to read the stored codes ( even a paper clip bent into a U shape will suffice ). Turn the ignition on (engine NOT running). Connect terminal A to terminal B with the wire (maintain this connection). Your service engine soon light will begin flashing. It starts with a code 12 to indicate its working : 1 flash, pause, 2 flashes. It will do this 3 times. Next comes your first fault code. For example if the code were 32, it would flash 3 times, pause, then flash twice. It will flash the error code 3 times, then flash the second error code( if there is one) then third, etc. When all the codes have been displayed, it then flashes code 12 again to indicate its done.
