* The driver intentionally turned it off: Many vehicles have a button or switch to manually disable traction control. Check your dashboard and owner's manual to see if there's such a switch.
* A malfunction in the system: A problem with any component of the traction control system (wheel speed sensors, ABS module, etc.) can cause the light to illuminate. This indicates a fault and requires diagnosis.
* A blown fuse: A blown fuse related to the traction control system will disable it and illuminate the warning light. Check your owner's manual for the fuse box location and diagram to check the relevant fuse(s).
* Low tire pressure: Significant differences in tire pressure between wheels can trigger the traction control light. Check your tire pressure and inflate to the recommended pressure listed on the sticker inside your driver's side doorjamb.
* Faulty wheel speed sensor: A faulty wheel speed sensor can send inaccurate information to the traction control module, causing the light to come on. This is a common cause.
What to do:
1. Check the owner's manual: Your manual will have a section on the traction control system and its warning light, which can provide troubleshooting tips.
2. Check for a manual switch: Look for a button or switch in your dashboard labeled "TC," "Traction Control," or a similar designation. If it's on, the system is intentionally off.
3. Check the tire pressure: Make sure all tires are inflated to the proper pressure.
4. Check the fuses: Inspect the fuses related to the traction control system.
5. Have the system diagnosed: If none of the above solves the problem, take your Concorde to a qualified mechanic or auto parts store with diagnostic capabilities. They can use a scan tool to read the fault codes stored in the car's computer, pinpoint the problem, and recommend a repair. Ignoring a consistently illuminated traction control light is not recommended, as it can affect your vehicle's handling and safety.
