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.
If your vehicle is equipped with the Traction Control system, this message will stay on a few seconds after the traction system stops limiting wheel spin.
This message will appear when the traction control system is limiting wheel spin. Keep in mind that when the warning lights turn on, a fault code is stored in the ABS
control module (in this case). Retrieving, diagnosing, and repairing any ABS system
faults will be necessary to keep the light off. A common fault with ABS
systems are the wheel speed sensors, stored codes may confirm this.
This is the ASC indicator. It comes on when the system is turned off.
To get the light out, turn the system back on by pushing the ASC(dsc) button
on the console. It's located just ahead of the shift lever. ASC is the
Automatic Stability Control system. It's a traction control light. it warns whenever the system is turned on
and the car senses a loss of traction. you can deactivate the system by
pushing the ASD(dsc) button and holding. this light will illuminate to say:
you may lose traction. Can sometimes be activated by faulty brake(ABS) sensors,ABS pump,While checking ensure that your brake pads aren't worn right down. If the light still stays up get your local service dealer to scan cars computer for fault code relating to which sensor is perhaps faulty. I hope this helps you or get back with your findings
If your trac and abs are both on. the problem could be a wheel speed sensor.
on some GM cars this sensor is built into the vehichles hub unit. making the bering and sensor one sealed unit. cheap hub units can be gotten (under 100 bucks) at autozone
Have your brake pads and rotors checked if you have worn pads this will activate the ABS Antilock Braking System light. The ETS Electronic Traction System uses this ABS to prevent skidding if the tires should lose traction.
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.
