Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal 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 sensors using a clean cloth.
Check connectors for tightness and any signs of corrosion. Repair or replace as necessary.

3. Check ABS Module and Wiring

Trace the wiring harness connected to the ABS module for any visible damage or wear.
If damaged, replace the wiring harness.
Inspect the ABS module for corrosion or fault codes; if faulty, replacement may be necessary.

4. Brake Fluid Level Check

Open the hood and locate the brake fluid reservoir.
Check the fluid level; if low, top it off with the recommended brake fluid type (DOT 3 or DOT 4).
Inspect for any leaks in the brake lines or connections.

5. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal securely.
Use the OBD-II scanner to clear any stored error codes.
Perform a test drive to verify the traction control light is off.
