2002 MonteCarloSS 35,700 miles
For the past 500 miles or so Ive been having what sound like passlock trouble. But a little different than what Ive read here.
When cold it will always start, after a little while the security light comes on and ding ding ding andI look and see the volt meter reading a big fat 0 then the lights will alternate security, battery, service engine soon.
Then the volt meter with resume reading 14 volt or so and all lights will go out except the security light, for a few minutes then ding ding ding and we are at it again. Some times the traction light will come on but not very often.
A few times the car would not start untill I played with the locks on the ket fob. Once I had to wait 10 minutes to start and once I had to do the 10 minute relearn thing but most of the time it will start just the lights come on and the volt gauge goes off.
I bought a obd2 reader off e-bay and later found out it was only good for engine codes.
Im thinking of the resistor fix, but wondering if this problem could be in the BCM ?
Any thoughts???????????????????????????????????????:uh oh:
