Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, brake fluid.
Ensure the vehicle is parked on a level surface and the ignition is turned off.
Disconnect the negative battery terminal to prevent electrical shorts while working.

2. Inspect and Replace ABS Wheel Speed Sensors

Locate the ABS wheel speed sensors at each wheel hub.
Remove the retaining screws using a socket set.
Disconnect the wiring harness from the sensor.
Remove the sensor from the hub assembly.
Clean the sensor mounting area to prevent debris from affecting the new sensor.
Install the new sensor in reverse order, tightening to manufacturer specifications (usually around 10-15 ft-lbs).
Reconnect the wiring harness and ensure it is secure.

3. Check and Replace ABS Fuses

Open the fuse box and locate the ABS fuses (refer to the owner’s manual for exact locations).
Remove the fuses using a fuse puller or needle-nose pliers.
Inspect the fuses for continuity; replace any blown fuses with new ones of the same amperage.
Close the fuse box securely.

4. Brake Fluid Inspection and Replacement

Check the brake fluid level in the master cylinder reservoir; add fluid if low (DOT 3 or DOT 4 as specified).
If the fluid is contaminated or old, perform a brake fluid flush:
- Remove the old fluid by siphoning from the reservoir.
- Refill with fresh brake fluid.
- Bleed the brakes at each wheel to remove air bubbles.

5. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal and ensure it is tightened securely.
Use the OBD-II scanner to clear any stored ABS fault codes.
Test drive the vehicle to ensure the ABS light does not re-illuminate.
