Affected Component

Electrical

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect battery before working on electrical systems.
•Allow the vehicle to cool before inspecting brakes to avoid burns.

Symptoms

•Traction control light illuminated on the dashboard
•Reduced engine power during acceleration
•Unusual behavior during slippery conditions (e.g., excessive wheel spin)
•Warning messages on the display (if equipped)
•Possible check engine light may also be illuminated

Diagnostic Steps

1
Scan for error codes using an OBD-II scanner to identify specific faults.
2
Inspect wheel speed sensors for damage, dirt, or corrosion.
3
Check the brake system for any malfunctions, as traction control relies on brake intervention.
4
Examine the ABS system for faults, as traction control is often integrated with ABS functionality.
5
Verify the traction control switch for proper function and ensure it is not accidentally turned off.
6
Inspect the engine control module (ECM) for software updates or faults.

Solution
