Solution

1. Preparation

Gather necessary tools and parts before starting the repair.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to prevent electrical shorts during the repair.

2. Inspect and Clean Wheel Speed Sensors

Tools Required: Socket set, cleaning brush, brake cleaner.
Remove the wheel from the affected side (if necessary).
Locate the wheel speed sensor; it is usually mounted near the brake rotor.
Clean the sensor using brake cleaner and a brush to remove any dirt or debris.
Reinstall the wheel and tighten the lug nuts to the manufacturer’s specified torque.

3. Check Wiring and Connectors

Tools Required: Multimeter, electrical connector cleaner.
Inspect the wiring harness for frays, breaks, or corrosion.
Use a multimeter to test for continuity in the sensor wires.
Clean electrical connectors with a connector cleaner to ensure a good connection.

4. Brake Fluid Level Check

Tools Required: Brake fluid.
Open the hood and locate the brake fluid reservoir.
Check the fluid level; if it is low, top it off with the correct type of brake fluid as specified in the owner’s manual.

5. Test ABS Module

Tools Required: OBD-II scanner.
Reconnect the battery.
Use the OBD-II scanner to check for any ABS-related fault codes.
If codes are present, refer to the manufacturer's service manual for further troubleshooting.
