Disconnect the vehicle's battery to prevent electrical shock.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.

2. Inspect and Clean Wheel Speed Sensors

Tools Required: Socket set, brake cleaner
Locate the wheel speed sensors at each wheel hub.
Remove the sensor bolts and gently pull the sensors out.
Clean the sensors and their mounting areas with brake cleaner.
Reinstall the sensors and secure them properly.

3. Check and Replace ABS Fuse if Necessary

Tools Required: Fuse puller or needle-nose pliers
Locate the ABS fuse in the fuse box (refer to the owner’s manual for exact location).
Inspect the fuse for continuity. If blown, replace it with a fuse of the same amperage.

4. Repair or Replace Damaged Wiring/Connectors

Tools Required: Multimeter, electrical tape, wire connectors
Visually inspect the wiring harness and connectors for damage.
Use a multimeter to check for continuity in the wiring.
Repair any damaged wires or replace connectors as necessary.

5. Test the ABS Pump

Tools Required: Brake pressure gauge
Locate the ABS pump and check for any visible leaks or damage.
With the ignition on (engine off), apply the brakes and listen for the pump operation.
If the pump does not operate, it may need to be replaced.

6. Reconnect Battery and Clear Codes

Reconnect the vehicle's battery.
