Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and turn off the engine.
Disconnect the negative battery cable to prevent electrical shorts during repairs.

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.
If damaged, replace the sensors with new ones.
Reconnect any loose wiring or connectors.

3. Check and Replace Brake Pedal Switch

Locate the brake pedal switch, typically near the top of the brake pedal assembly.
Disconnect the electrical connector from the switch.
Use a multimeter to test for continuity when the brake pedal is pressed. Replace the switch if there is no continuity.
Reconnect the switch and ensure it is securely mounted.

4. Inspect ABS Control Module

Remove the necessary panels to access the ABS control module.
Check for any visible damage or corrosion on the module connectors.
If fault codes indicate module failure, replace the ABS control module following the manufacturer’s instructions.

5. Reconnect Battery and Clear Codes

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