Why is my ABS and TRAC off light on?
The ABS and Traction Control lights come on whenever the vehicle’s computer or PCM detects a malfunction, a faulty wheel sensor, or other mechanical failures. These warning lights do not imply anything severe by themselves but may point to a graver problem when paired with the main brake light going off.
What does the Trac Off light mean on a 2000 Pontiac Grand Am?
“Trak Off” means that the traction control button is off or the wheels spun and the engine is at reduced power.
How do you troubleshoot traction control problems?
Turn your vehicle off, then restart it. If the traction control warning light stays off, there was a momentary glitch in the system, and you should be fine to continue. But if the light comes back on and stays on, you should call your mechanic right away and schedule a service appointment.
How do you reset the ABS light on a Pontiac Grand Am?
Electrical System
- Open the hood and turn off the Grand Prix’s engine.
- Disconnect the battery from the vehicle using a socket wrench. Wait three minutes. Reconnect the battery and turn the engine on to check the ABS light. If it is off, the sensor is reset. Close the hood.
Can bad brake pads cause ABS light to come on?
To Be Clear, Worn Brakes CAN Cause The ABS Light To Come On, But It’s Not Why You Think. Your ABS system has its own electrical control unit which is separate from your braking system, even though the ABS and your brakes work together. In about 90% of cases, your ABS light is not caused by worn brake pads.
What does it mean when the Trac Off light comes on in your car?
Traction Control
“TRAC OFF” Indicator Indicates that Traction Control is off. The TRAC system switches the traction control on/off to prevent wheelspin and further downshifting. Press the switch again to turn the system back on.
Why is my traction control light staying on?
When the traction control warning light stays on, that means you aren’t getting any help from the system to control traction and the system needs to be checked. Some systems are so sensitive that at the first sign of wheel slip, they immediately reduce power or apply the brakes so much that you go nowhere.
How to troubleshoot a Grand Prix ABS light and traction?
Low fluid level in the brake master cylinder will result in shutdown of the ABS and Traction Control system to prevent introduction of air into the brake system. Turn the ignition key off and insert the scan tool’s connector into the vehicle’s diagnostic connector.
How does traction control work in a Grand Prix?
The anti-lock braking system (ABS) and Traction Control systems in your Grand Prix both use the ABS wheel-speed sensors and modulator valve assembly to control wheel slip. The ABS system monitors the wheel-speed sensors and relieves brake pressure on a wheel that it senses is nearing lock-up.
What causes wheel lock up on Grand Prix?
Check the tires for proper wheel size and check the fluid level in master cylinder. Improper tire size, such as two different sizes, will cause the wheels to turn at different speeds and may set a false code when the computer senses this as potential wheel lock-up.
Where is the wheel speed sensor on a Grand Prix?
Unplug the faulty wheel speed sensor, located on the back of the wheel bearing and hub assembly at each wheel in the Grand Prix and test the resistance of the sensor using your digital volt/ohm meter set to read resistance. The resistance of a good wheel speed sensor will be1k ohms +/- 10 percent.
