Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Remove any dirt or debris around the sensors using a soft brush or cloth.
Disconnect the sensor connector and inspect for corrosion or damage.
If necessary, replace the sensor with a new one.

3. Check and Refill Brake Fluid

Locate the brake fluid reservoir under the hood.
Check the fluid level against the minimum and maximum indicators.
If low, fill with the appropriate brake fluid type as specified in the owner’s manual.
Reconnect the battery and check if the light turns off.

4. Test ABS Module

Using a multimeter, check for proper voltage at the ABS module.
If the module is faulty, remove it by disconnecting the wiring harness and unbolting it from its mount.
Replace with a new ABS module and reconnect all wiring.

5. Final Assembly and Testing

Reconnect the battery and start the vehicle.
Test drive the vehicle to ensure the traction control light does not re-illuminate.
