Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure the vehicle is on a level surface and secure with wheel chocks.

2. Inspect Wheel Speed Sensors

Tools Required: Socket set, multimeter
Remove the wheel on which the sensor is located.
Locate the wheel speed sensor and inspect the wiring harness for frays or breaks.
Use a multimeter to check resistance across the sensor terminals; compare values to manufacturer specifications.
If the sensor is faulty, proceed to remove and replace it.

3. Check Brake Fluid Level

Locate the brake fluid reservoir under the hood.
Ensure the fluid level is above the minimum mark; top up with the correct type of brake fluid if low.
If the fluid is contaminated or old, drain and replace with fresh brake fluid.

4. Inspect ABS Module

Tools Required: Socket set
Access the ABS module by removing any covers as necessary.
Check for any signs of corrosion, loose connections, or damaged wiring.
If the module is faulty, replace it following the manufacturer’s instructions.

5. Clear Error Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any existing error codes and reset the traction control light.
Test drive the vehicle to ensure that the light does not reappear.
