I have a Chevy equinox 2006 and last week both ABS and TC warning lights came on. I had no locking pulsing or tremors, in other words the vehicle runs fine. On a whim I checked the tire pressure and sure enough the rear tires were low. After I added air...the lights stayed off( Until today). Once again the lights came on and NO Problems>>>>so i rechecked and added air again...the lights came on shortly after then went off when I restarted the car, only to come on again... Since there are no obvious symptoms like shaking or pulsing I am going to disengage the Black or (-) terminal from the battery to reset the computer. We will see then. Once again...my lights came on without any issues.
