⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery to ensure safety while working on electrical systems.
•Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

Symptoms

•Traction control light illuminated on the dashboard
•Unresponsive traction control system
•Vehicle slipping or losing traction during acceleration
•Sudden activation of traction control at low speeds
•Warning message displayed on the instrument cluster
•Reduced engine power during acceleration

Diagnostic Steps

1
Scan the vehicle's onboard computer using an OBD-II scanner to check for any stored error codes related to the traction control system.
2
Inspect the wheel speed sensors for dirt, damage, or disconnection, as these are critical for TCS functionality.
3
Check the brake light switch operation, as it can influence the traction control system’s behavior.
4
Examine the ABS control module and wiring for signs of damage or corrosion.
5
Inspect the vehicle's tires for uneven wear or incorrect pressure, which can affect traction control performance.
6
Verify that the vehicle's traction control switch is functioning correctly and not stuck in an 'off' position.

Solution
