ok first it is a 2001 monte carlo with the 3.4 engine

when i bought the car it had a couple light on the dash
ABS and Trac Off are lit all the time, when i first start the car for about a minute the message center displays Service Traction System.
the Air Bag light is always on
recently the brake light pops on. i have solid brake pedal brand new drilled and slotted rotors with new ceramic brakes and the reservoir is full with clean synthetic fluid.
also no reverse lights, the bulbs are good they are getting no power

i am starting to think that the BCM may be the whole problem. what do you guys think ?

 

i have a 98 and when my light came on it was one of the abs sensors, but i dont know if my low trac light was on cause the bulb was burned out. and it my just be a short in the wiring for the back up lights

 

The weel bearing have a sensor for the ABS and the Track, i have to change the bearing on the left front weel on my 2001 Monte Carlo, even do the bearing is fine . all because the sensor failed, there is no danger or problem using your car with those lights on. You just don't have Breaking and traction assistance.

You can use a abs code reader to find out witch weel is faulty.

For the rest i am not sure, i had a problem with the air bags to on my car, but i had it fix some time ago and i am not sure what they changed.

Hope this helps peace

 

the scanner says it is the left rear speed sensor. and i know all of these issues can be fixed but it just seams so weird to have all of these issues happening at once when the car only has 70,000 miles on it.

 

Does your car have a driver seat with an air bag? Sometimes people replace the driver seat and don't replace it with one with an airbag and just disconnect it so an air bag light is always on.

ABS/Trac Off AND service traction all the hub.

Brake light, I don't know. Maybe it's part of the reverse light problem? Could be an issue with the hazard switch, or the multi-function switch. Wiring is a pain in these cars.

 

Welcome to the world of General Motors products! They are all junk! Many electrical issues...Intake manifold issues due to cheap gaskets used etc...GM has the most problem cars out of any other make of vehicle!These issues arent wierd that you are experiencing cashmoney...They are typical GM issues in a 70K mile GM vehicle and sometime occur all at once! Sometimes i think their vehicles are designed to do that at a certain mileage......it sures seems that way! Good Luck!

 

^ How was that a productive post? Every car and every car company has problems.

I believe mostly everything of his is just due to a wheel hub. Those go, or connections get dirty. That's nothing major.

 

a friend that has a Tech II scanner at work is going to bring it home with him for the weekend so i will be finding out the problem for sure before throwing money into any unneeded parts.
wish me luck

 

Good Luck CashMoney....hope its something not too expensive for you to repair!
