Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is on a level surface with the parking brake engaged.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect Wheel Speed Sensors

Tools Required: Socket set, multimeter
Remove the wheel from the affected corner (if necessary) to access the wheel speed sensor.
Unplug the wheel speed sensor connector.
Use a multimeter to test the resistance of the sensor; it should fall within the manufacturer's specified range.
Clean the sensor and mounting area if dirt or debris is present.
Reinstall the sensor and connector, ensuring it is secure.

3. Inspect ABS Fuse and Relay

Tools Required: Fuse puller or tweezers
Locate the ABS fuse in the fuse box (refer to the owner's manual for specific location).
Remove the fuse and check for continuity; replace if blown.
Test the ABS relay by swapping it with a similar relay (if available) to see if the ABS system resets.

4. Inspect ABS Module and Wiring

Tools Required: Socket set, wire brush, electrical cleaner
Access the ABS module, usually located near the brake master cylinder.
Check for any visible signs of damage or corrosion on the module and connectors.
Clean any corrosion with electrical cleaner and a wire brush.
Reconnect and ensure all connections are tight.

5. Clear Codes and Test Drive

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored ABS codes.
Start the vehicle and take it for a test drive to ensure the ABS light does not re-illuminate.
