Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to ensure safety while working on electrical components.

2. Inspect and Clean Wheel Speed Sensors

Tools Required: Ratchet and socket set, cleaning brush, and electrical contact cleaner.
Remove the wheel covers or wheels if necessary to access the wheel speed sensors.
Clean the sensors and the surrounding areas using the cleaning brush and electrical contact cleaner.
Reinstall any removed components.

3. Check Brake System

Tools Required: Brake caliper tool, torque wrench.
Inspect brake pads for wear and replace if necessary.
Ensure that brake calipers are functioning properly and free of debris.
Torque caliper bolts to manufacturer's specifications (typically 14-20 ft-lbs, check specific torque value).

4. Inspect Wiring and Connectors

Tools Required: Multimeter, wire brush.
Visually inspect the wiring harness connected to the wheel speed sensors and ABS module.
Use a multimeter to test for continuity and proper voltage.
Clean any corroded connectors with a wire brush and electrical contact cleaner.

5. Reconnect Battery and Test

Reconnect the negative terminal of the battery.
Start the vehicle and check if the traction control light remains illuminated.
