hi Ivan, i have tried the 30 min relearn. sorry i wasn't clear about that. i have also disconnected the battery for over 30 mins. i have spark no fuel. and theft light remains on does not flash or go off after 10 mins or 30mins. (3x ten min with key on) i have tired to leave key on for full 30 mins as well to see if theft light would go off. it still remains on.?
yes. i have tried both keys. i work part time for a security company this is one of there patrol cars. i have had problems before with the pass lock systems on some of them before, but the theft light would be blinking and the 10-30min reset would work. but this one has me scratching me head..
i have an actron cp9580 after scaning it shows no codes stored.
the only thing i can find in Alldata is this, about a steady theft light but dont give any procedure
When the PCM receives the correct password, the PCM enables the fuel injection system, allowing the vehicle to operate correctly. The PCM may allow the car to start and quickly stall during a failed theft condition.If the BCM does not receive a Passlock(TM) data value, the BCM will enter a short tamper mode. During this mode, the VTD system will not allow the car to operate for 4 seconds. If the Passlock(TM) data value is incorrect, the VTD system will enter the long tamper mode. In the long tamper mode, the following actions will occur:
Although the vehicle may start, the engine will quickly stall due to a fuel cut-off.In the event of an open in the serial data communication between the BCM and the PCM or a failure in the Passlock(TM) lock cylinder, the following actions occur:
If a failure occurs when the ignition is off, while the VTD system is not fail-enabled, the PCM will never receive a valid password, and will not allow vehicle operation by disabling the fuel injectors.
no. even auto zone wants almost 200 for lock cylinder. all there cars are 250k+miles and there running on dimes. hate to just start shotguning it..
no i don't.., not without taking it to the dealer. and any talk of that would probably get me fired just for the suggestion! LOL!!
can you give me the bypass procedure? I really need to know how they have 23 GM models for patrol cars and i am sure i'm going to run into this again
Ugg. that kinda sounds like a pain in the *** I did do something similar on one of there Malibu but you cut that yellow with car running. but sense i cant start the car that wont work.. i don't want to get anyone in trouble here.. but with these being fleet vehicles for Colorado Security Professionals LLC. i think it make sense for them to have a bypass procedure if there is one?
so am i understanding you correctly? that there is a bypass procedure that can be done without trying to match the resistors on the passlock wires. that can be obtained? thru dealer or? I mean, if there is we need to get it.. they patrol 24-7 and as there cars are getting up there in yrs and miles amd im seeing this problem more and more. this one left a patrol stranded for over 4 hrs two nights ago. and we had to have it towed into are shop as well. this is really becoming an issue
O i see.. thought you were saying there was a way to bypass it.. i was getting pissed. LOL! i talked to GM today and i was gona head down there with a word or two tomarrow.!
Well thanks for the try.. guess ill have to give that a try. cant spend 200 everytime one of these acts up..
no other suggestion that i try or check?
