Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to avoid any electrical issues.

2. Inspect Wheel Speed Sensors

Tools Required: Torque wrench, multimeter
Remove the wheel to access the wheel speed sensor.
Disconnect the sensor harness and use a multimeter to check for continuity.
Clean the sensor and its mounting area before reinstallation.

3. Check Brake Fluid Level

Tools Required: None
Open the hood and locate the brake fluid reservoir.
Inspect the fluid level; if low, top off with the manufacturer-recommended brake fluid.
Check for any leaks in the brake lines or around the master cylinder.

4. Inspect Wiring and Connectors

Tools Required: Wiring harness repair kit, electrical contact cleaner
Visually inspect the wiring leading to the traction control module and wheel speed sensors for fraying or corrosion.
Clean any corroded connections with electrical contact cleaner and re-secure.

5. Test ABS Module

Tools Required: OBD-II scanner
With the battery reconnected, perform a diagnostic check on the ABS module using the OBD-II scanner.
Clear any stored codes and test drive the vehicle to see if the traction control light returns.
