You most likely have a bad abs speed sensor on one of you wheels. Have it scanned by someone.

Abs light came on

What it looks like: The traction control warning light typically takes the form of the acronym "TC." Sometimes this light is a small illuminated picture of a car losing control What it looks like: The traction control warning light typically takes the form of the acronym "TC." Sometimes this light is a small illuminated picture of a car losing control. How this system works: Traction control uses wheel speed sensors to detect when one or more of the car's wheels lose grip and traction. When the system registers a loss of traction in one or more of the wheels, a computer will limit power to the wheels that are still in solid contact with the road to prevent a skid. Common reasons for this to happen:
  • ABS is malfunctioning: Traction control and ABS (anti-lock braking system) often share the same control module and internal self-diagnostics system. As a result, sometimes an issue in the ABS can trigger the traction control light. If this is the case, then both the ABS and Traction Control lights will be on.
  • Broken wheel speed sensors: Wheel speed sensors are usually in the wheel bearing assembly, and determine the rate at which each wheel is moving. The sensors relay that information to the traction control module, which determines whether or not power needs to be shifted. Wheel speed sensors can get dirty or damaged and stop working, which prohibits the traction control module from knowing when to enable the system.Traction control module is faulty: The traction control module - which, again, is often shared with the ABS - can malfunction and break altogether, causing the system to stop working. What to expect: A top-rated mobile mechanic will come to your home or office to determine the source and cause of the traction control issue, and will then provide a detailed inspection report that includes the scope and cost of the necessary repairs. How important is this service? It's important to have the traction control issue investigated as soon as possible, as adverse driving conditions can arise at any time. While your car is unlikely to incur further damage from a faulty traction control system, it won't be safe to drive in rain, snow, sleet, or other inclement weather, or even possibly through pools of water on the road. Furthermore, the issue that is causing the traction control light to illuminate could also be impacting the ABS.

It is very common for all of these lights to come on all at the same time. They are all related to your Antilock Brake and Traction control system. ABS = Antilock Brake System, TRAC OFF = the traction control system is disabled - either because there is a malfunction in the ABS system or you have turned off the traction control button. VSC = Vehicle Skid Control. - (which uses the ABS and the Traction Control to function.)

The most common cause of these lights coming on is one or more defective wheel speed sensors. Although there are many other possible causes as well. Your ABS and Traction Control system must be scanned for fault codes to diagnose the problem. If you had damage to your wheels/axles during your "fender bender" this may have something to do with it. Otherwise it may just be coincidence that part of these systems failed right after your accident.

Hi,the traction control light coming up means there is a fault detected in the system and a scan tool will be required to learn what fault has been detected. Possible steering angle sensor, wheel speed sensor or brake pressure sensor since the light comes up when making turns or when backing up. Faults are to be checked and proper diagnostic procedures carried out before parts replacement remedies.....

Abs light, trac light, service engine soon light 2001 Pontiac Grand Am

Sounds like you have a bad wheel speed sensor. You need to have it scanned. Since it's been sitting, it might just be a bad connection to one of the speed sensors.

2003 Chevy Impala Service Traction Sytem show on Dash

I can't answer the question about the gas fumes, but I had the same problem last year with the "Service Traction Sysytem" message and the Trac and ABS lights coming on in my Impala. Mine turned out to be because of a bad wheel bearing, that was causing the ABS and traction system not to work. I'm not sure if you've experienced this, but another thing that would happen with mine was that I would go to brake and have a hard time depressing the brake pedal, almost like it was pushing back. That is the point when the Trac and ABS lights came on.

2001 olds ABS and traction control sensor issue

An ABS sensor DOES affect the traction control system. Traction control uses these sensors to determine if a wheel is losing traction. A bad sensor will cause both the ABS and TRACTION lights to come on.
The CHECK ENGINE light however is going to be a seperate problem.
