Solution

1. Preparation

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

2. Inspect and Replace ABS Fuse/Relay

Locate the fuse box in the engine compartment.
Remove the ABS fuse using a fuse puller or needle-nose pliers.
Inspect the fuse for continuity; replace if blown.
Check the relay for signs of damage; replace if necessary.

3. Clean or Replace Wheel Speed Sensors

Raise the vehicle using a jack and secure it with jack stands.
Locate the wheel speed sensors at each wheel hub.
Clean the sensors with brake cleaner and a lint-free cloth.
If damaged, remove the old sensor using a socket set, and install a new sensor, tightening it to the manufacturer's specifications.

4. Repair Wiring Harness

Visually inspect the wiring harness connected to the ABS module for any frays or corrosion.
If damage is found, repair or replace the wiring as needed, using appropriate connectors and soldering techniques.
Ensure all connections are secure and insulated.

5. Test ABS Functionality

Reconnect the battery and start the vehicle.
Conduct a test drive to check if the ABS light remains off and the brakes function correctly.
If the light is still on, additional diagnostics may be necessary, potentially involving the ABS control module.
