Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to avoid electrical shorts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.

2. Inspect Wheel Speed Sensors

Sub-steps:
- Remove the wheel from the affected side using a socket set.
- Locate the wheel speed sensor and disconnect the electrical connector.
- Clean the sensor and the mounting surface to remove any debris.
- Reconnect the sensor and ensure it is properly seated.
- Reinstall the wheel and lower the vehicle.

3. Check the Traction Control Fuse

Sub-steps:
- Locate the fuse box, typically found under the dashboard or in the engine compartment.
- Identify the fuse for the traction control system using the fuse diagram.
- Remove the fuse using a fuse puller and inspect it for continuity.
- Replace the fuse with a new one of the same amperage if it is blown.

4. Test Brake Pedal Switch

Sub-steps:
- Locate the brake pedal switch near the top of the brake pedal.
- Disconnect the electrical connector from the switch.
- Use a multimeter to test for continuity when the brake pedal is pressed.
- If the switch is faulty, replace it with a new switch and reconnect.

5. Inspect ABS Module

Sub-steps:
- Check for any visible damage or leaks in the ABS module.
- Use a scan tool to check for any ABS error codes.
- If necessary, replace the ABS module based on diagnostic results.
