Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to prevent electrical shorts.

2. Inspect Wheel Speed Sensors

Tools Required: Multimeter, socket set
Remove the wheel on the affected corner (if necessary) to access the wheel speed sensor.
Disconnect the wheel speed sensor connector.
Use a multimeter to check the sensor's resistance; it should be within the manufacturer's specified range. If not, replace the sensor.
Reconnect the connector and reinstall the wheel.

3. Check ABS Module

Tools Required: OBD-II scanner, socket set
Reconnect the battery and start the vehicle.
Using the OBD-II scanner, check for any ABS-related fault codes.
If codes are present, refer to service manual for specific troubleshooting steps regarding the ABS module.
If the module is faulty, remove it by disconnecting the wiring harness and unscrewing the mounting bolts. Replace with a new ABS module.

4. Test Brake Light Switch

Tools Required: Multimeter
Locate the brake light switch near the brake pedal.
Disconnect the switch connector and test continuity with a multimeter. If there’s no continuity when the pedal is pressed, replace the brake light switch.

5. Inspect Fuses

Tools Required: Fuse puller or needle-nose pliers
Locate the fuse box (check owner's manual for location).
Identify the traction control system fuse and pull it out for inspection.
Check for a blown fuse and replace it if necessary.
