Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and the engine is turned off.
Disconnect the negative battery terminal to avoid electrical issues.

2. Inspect ABS Fuses

Locate the fuse box; refer to the owner's manual for the exact location.
Remove the cover and check the ABS fuse using a multimeter.
- If the fuse is blown, replace it with a fuse of the same amperage.
Reinstall the fuse box cover.

3. Clean or Replace Wheel Speed Sensors

Jack up the vehicle and secure it on jack stands.
Remove the wheel to access the wheel speed sensor.
Disconnect the sensor connector and inspect the sensor for dirt or damage.
- Clean the sensor with electrical contact cleaner if dirty.
- If damaged, replace the wheel speed sensor with a new one.
Reinstall the wheel and lower the vehicle.

4. Inspect Wiring and Connectors

Locate the wiring harness connected to the ABS module.
Visually inspect for any signs of wear, fraying, or corrosion.
If any issues are found, repair or replace the damaged wiring or connectors.

5. Test ABS Module and Pump

Reconnect the negative battery terminal.
Use an OBD-II scanner to clear any existing ABS fault codes.
Perform a test drive to see if the ABS light returns. If it does, the ABS module may need to be replaced.
