Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hello, I am Daniel. I may ask you questions, to better answer you. Please let me know if you have any other questions before you Accept.
Have you done the reset of on for 10 minutes and off for 6 seconds 3 times in a roll?
The Passlock System is designed to prevent theft even if various theft deterrent parts are changed. Parts that can no longer be changed without the possibility of going into a tamper mode are:
If any of these parts are replaced, the vehicle may start and stall for 10 minutes (Long Tamper Mode). If this occurs, the system must go through a Long Tamper Mode cycle. During this time, the THEFT SYSTEM indicator will be flashing for the full ten minutes and DTC B303 1 will be set. The BFC and PCM require the full ten minutes to complete a learn cycle. The Ignition Switch must remain in the RUN position until the THEFT SYSTEM indicator stops flashing or the cycle will have to be repeated.
So the question is which module needs to be replaced. throwing parts at it may be expensive. you could try a salvage yard.
I understand but my THEFT SYSTEM indicator never flashes it remains on SOLID all of the time. So what would cause that?
