    I too have a 02 Alero and the TRAC OFF light has come on. I just had the water pump replaced along with the timing chain and then a sensor went out. I just got it back then drove it today and the TRAC OFF light has come on.

    If it isn't one thing it's another!!!!!!!!!!!!!!!!!!!!!!!!!

I'm not a mechanic but I've had this problem with a dodge truck and a Saturn. I bought a new gas cap and the problem stopped. It takes awhile after you install the new cap for the emmission control system to clear. Something about air gas mix. I don't know about the Trac problem.

Need to turn the caution lights off on the dashboard


Well ,that's because there is a problem with the system an there are What are call DTC'S -diagnostic trouble codes stored in the modules , computers ! You need to take to a repair facility that has a professional grade scan tool that can read codes in the body control module !
SERVICE VEHICLE SOON
The IPC illuminates the SERVICE VEHICLE SOON in the following conditions:
?€¢
The BCM detects certain malfunctions in the lighting system. The IPC receives a class 2 message requesting illumination from the BCM.


?€¢
The IPC detects a loss of class 2 communication with the BCM.


This year vehicle as with all newer vehicles have several control modules that control the engine , air bags , antilock brakes , anti-theft system ,Heating an air conditioning ,the instrument cluster an some others ! These modules are all connected on a class 2 serial data communication network so the modules can share information ! Your best bet is to take it to GM dealership or a ASE certified repair shop before you guess an just replace parts , that will cost you more in the long run !

Service Vehicle Soon, Trac Off and Anti Lock dashboard lights are on, what does that combination mean is wrong?


You will need the Engine computer and the ABS scanned for codes, they could overlap?

As I was driving down the road, all at once 4 warning lights came on my dash at once (Check Engine Soon, Service Engine Soon, ABS, & Trac Off Indicators). What could be wrong, the car still ran fine...


It's most likely going to be the wheel speed sensor which is located at the wheel bearing. when they become disconnected or the wire breaks your abs and traction light will come on and something your check engine light.

Service engine soon/ABS/Trac lights are staying on


Have the ABS codes scanned. This will get you started in the right direction. Possibility is that one or more of the wheel speed sensors is not working or intermittent - could be wiring or connectors on these as well. Another possibility is the EBCM, Electronic Brake Control Module. I believe the EBCM will throw 1216 code in many cases. THese can be rebuilt online for about $150.00.
The more likely problem is the wheel speed sensors. THese are an integral part of the wheel hub. About $100.00 each for the part. About $250.00 each to have them replaced. They can be tested with an AC voltmeter by spinning the wheel. Also, they should read roughly 850 ohms resistance. The ABS codes will tell you which ones are not reporting.

ABS, brake, trac control, service engine soon light came.


I'm sorry to say that you will need to see a dealer or repair shop so they scan your ABS for trouble codes first and then find your problem.

Anti lock light and so on , is on


Your vehicle’s computer system has self-testing capability. When the computer senses that there is a problem with some of the components it stores the correspondent trouble code(s) in its memory and lights up the Check Engine, Service Engine Soon, ABS Or TC lights to tell you that there is a problem and you should have the car diagnosed and repaired. I would take it to a service center you trust and let then come up with a solution. Sometimes a problem in one system will turn light on for other systems that communicate with it, but it doesn't mean there is a problem in all of the systems.
