Re: Multiple engine codes
By the way, if there is a ground strap on the PCM chassis, that is not the one used for switching to ground. You have to measure on connector C1 point 31 and 32 for 0 Ohms to ground. By the way, if you would get a PCM from any place, it has to be loaded with your vehicles VIN and if you have Sentry key system, that one has to be loaded as well. (or you could ask the dealer to program the PCM to use without the sentry key system, so that you could use a normal key instead)
