Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, torque wrench.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any dirt or debris around the sensor area.
Disconnect the electrical connector from each sensor.
Use a multimeter to test the sensor's resistance; it should typically be within the manufacturer's specifications.
Clean the sensor using a soft cloth and electrical contact cleaner.
Reconnect the sensors and secure any loose wiring.

3. Check ABS Module

Locate the ABS control module, usually found near the brake master cylinder or under the hood.
Inspect the electrical connectors for corrosion or damage.
Reconnect the ABS module securely.
If necessary, follow the manufacturer's procedure to reset the ABS/traction control system.

4. Verify Tire Condition

Check each tire for proper inflation using a tire pressure gauge; inflate to the recommended PSI as indicated on the vehicle door jamb.
Measure tread depth on all tires to ensure they meet the minimum safety requirement (typically 2/32 of an inch).
Replace any tires that are excessively worn or mismatched.

5. Reconnect Battery and Test System

Reconnect the battery terminal securely.
Start the vehicle and check if the traction control warning light is still illuminated.
Take the vehicle for a test drive to ensure the traction control system is functioning correctly.
