Re: Passlock System

I have read this entire thread and there is a ton of enlightening info here. I too am experiencing the passlock nightmare. the "theft system" light was on steady,cranked but no start.After trying the reset method in owners manual for passlock 2 with light remaining on and no start I began reading this thread. Since then I have tried all the methods suggested still no start. I checked the resistance from the reference wire(black) to the data wire(yellow) after cutting, I did this by turning the key to start with the vehicle in reverse. I read 1760 ohms( checked 2X) after installing the resistors(1750 measured) the light has gone out. I tried the reset/relearn steps again and still not starting. could the R value be wrong or is the problem something else, BCM maybe? Please help this is just the latest battle with this car. This is an 04 Malibu classic 2.2, auto trans, 150k, no reader so no codes, recent work: brakes, new cylinder head complete, exhuast manifold. If it is the BCM will I be able to use the relearn or does it need to go to the dealer for reset? I have not been able to get it started since the light first came on,or since the light has gone out.
