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 off.
Disconnect the battery to prevent electrical shorts during the repair.

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.
Check the wiring and connectors for damage; repair as necessary.
Reconnect the sensors and ensure they are secured properly.

3. Check and Top Off Brake Fluid

Locate the brake fluid reservoir under the hood.
Inspect the fluid level; if low, add the manufacturer-recommended brake fluid.
If the fluid appears contaminated, plan for a brake fluid flush.

4. Test ABS Module

Reconnect the battery, then use the OBD-II scanner to check for ABS codes.
If error codes are present, follow the manufacturer’s service manual for the ABS module diagnosis.
Replace the ABS module if it is found to be faulty.

5. Final Assembly and Battery Reconnection

Reassemble any components removed during inspection.
Reconnect the battery and ensure all connections are tight.
Clear any error codes from the system using the OBD-II scanner.
