Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to ensure safety during repairs.
Allow the vehicle to cool if it has been running.

2. Replace ABS Fuse (if blown)

Locate the fuse box under the dashboard or in the engine compartment.
Remove the fuse for the ABS system using a fuse puller.
Replace it with a new fuse of the same amperage.

3. Inspect and Clean Wheel Speed Sensors

Raise the vehicle and secure it on jack stands.
Locate the ABS wheel speed sensors on each wheel hub.
Remove any dirt or debris from the sensors using a clean cloth.
Check the sensor connectors for proper seating and corrosion; clean as necessary.

4. Repair or Replace Wiring/Connectors

Visually inspect the wiring harness leading to the ABS module for any signs of wear or damage.
If damaged, splice in new wiring or replace the entire harness as needed.
Ensure all connectors are securely attached and free from corrosion.

5. Test and Replace ABS Module (if necessary)

If the module tests faulty with a multimeter, remove it from the vehicle.
Disconnect the wiring harness and unbolt the module from its mounting.
Install a new or rebuilt ABS module by reversing the removal process.
Reconnect all wiring and secure the module in place.

6. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear stored ABS fault codes and reset the system.
