Re: 2002 GJCL, ABS light came on today and stays on. Alsp...
If the ABS lights stays on it means the computer has detected a problem in the anti lock brake system and has shut it off until it is repaired. You still have your regular brakes, just not the ABS parts. Could the smell be exhaust gas?

Sounds like two different problems. I would have the engine computer checked for trouble codes and the body computer for ABS codes. The brake problem could be the master cylinder, the gas smell could be a fuel leak or a problem with the venting system for the gas tank.
When your ABS light stays engaged after inital startup then that signifies a problem with the ABS system itself.Normally, this does not make the vehicle unsafe to drive, unless there is a noticeable fluid loss, which would give you a very poor brake pedal.Although this vehicle can still be driveable, the ABS sytem will not work, properly.........You can physically check the brake fluid level under the hood, and even remove the wheels to look at the brake material itself, but normally ABS lights signify a greater problem, which would require a scan tool (which runs about $800 U.S. Dollars) to diagnose properly.I hope I could help......rate me accordingly
Did you have the ABS sensors checked ?? The brake fluid level when low also activates the Brake and ABS lights?? Drive truck to an AutoZone store and ask to have computer codes scanned. This is a free service for all customers. This will help you to pinpoint the problem.
Check the E-Brake, make sure that the ebrake is not engaged and that it is fully disengaging. If that is not the problem, then there is something with the brake calipers or rotors that are not allowing your brakes to fully disengage
You most likely need to replace your brake switch, which is a
a $8 part. If you look up along the brake peddle you will see it depressing a switch. on the end of that switch is a electrical connector that you can press on one side to remove.
Once removed your brake lights will be disconected and your ABS
light should go off. You then need to replace the switch that it pluged in to.
I would still be suspect of the ABS module. Had the same thing happen on an 01 Tahoe.
Search the web for an ABS repair facility located in Russia, IA. They repair the module for $150.00 and give a 5 year warranty, which you can't get from the factory. And, their website has troubleshooting guides to help you determine if for certain the module is bad or has a probelm.
You can remove the module and continue to drive the vehicle. Their turn around is as they state, and once I had them make the repiars, my Tahoe has been up and running great!
