Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, brake fluid.
Safety Warnings: Ensure the vehicle is parked on a flat surface and the ignition is off before starting.

2. Check and Replace ABS Fuse

Locate the fuse box (refer to the owner’s manual for the exact location).
Remove the cover and locate the ABS fuse.
Use a fuse puller or pliers to remove the fuse and inspect it for continuity.
If the fuse is blown, replace it with a new fuse of the same amperage.
Reinstall the fuse cover and turn on the ignition to check if the ABS light is off.

3. Inspect and Replace Wheel Speed Sensors

Raise the vehicle using a jack and secure it on jack stands.
Locate the wheel speed sensors at each wheel hub.
Disconnect the harness connector from the sensor.
Remove the sensor using a socket set and inspect it for damage or dirt.
Clean the sensor and the mounting area.
If damaged, replace the sensor with a new one, reinstall, and reconnect the harness.

4. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Check the fluid level; if low, add OEM brake fluid up to the recommended level.
Ensure the reservoir cap is securely closed.

5. Test ABS Module and Wiring

Inspect the wiring harness leading to the ABS module for any signs of wear or corrosion.
Use a multimeter to check for continuity in the wiring.
If continuity is lacking, repair or replace the damaged wires or connectors.

6. Clear Codes and Test Drive

After all repairs, use the OBD-II scanner to clear any stored DTCs.
Start the engine and monitor the ABS light.
Take the vehicle for a test drive to ensure the ABS system is functioning properly and the light remains off.
