Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is turned off.
Disconnect the negative battery terminal to prevent electrical issues.

2. Inspect Wheel Speed Sensors

Tools Required: Multimeter, socket set.
Remove the wheel on the affected side.
Locate the wheel speed sensor and disconnect the electrical connector.
Use a multimeter to check the resistance of the sensor; compare with manufacturer specifications.
Clean any debris around the sensor and the tone ring.
Reconnect the sensor and wheel, ensuring all connections are secure.

3. Check Brake Fluid Level

Tools Required: Brake fluid (if needed).
Open the hood and locate the brake fluid reservoir.
Check the fluid level; it should be between the minimum and maximum marks.
If low, fill with the appropriate brake fluid type specified in the owner’s manual.

4. Inspect ABS Module

Tools Required: Diagnostic scan tool.
Reconnect the battery and start the vehicle.
Use the diagnostic scan tool to check for ABS codes.
If faults are present, repair or replace the ABS module as necessary.

5. Test Traction Control Switch

Tools Required: Multimeter.
Locate the traction control switch on the dashboard.
Use a multimeter to check for continuity when the switch is pressed.
Replace the switch if it fails to show continuity.
