Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove the sensor using a socket set (typically 10mm).
Clean any dirt or debris from the sensor and its mounting area using a clean cloth.
Reinstall the sensor and torque to the manufacturer's specifications (typically around 80 in-lbs).

3. Check and Replace Brake Pedal Switch (if necessary)

Locate the brake pedal switch, usually mounted above the brake pedal.
Disconnect the wiring harness from the switch.
Remove the switch using a socket set or wrench.
Install the new switch and reconnect the wiring harness.

4. Inspect ABS System

Locate the ABS module, usually found near the brake master cylinder.
Check for any visible leaks or damage.
If codes indicate a specific ABS issue, follow the manufacturer's repair instructions for that component.

5. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any fault codes.
Start the vehicle and check if the traction control light remains off.
