Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace ABS Fuse

Locate the fuse box (refer to the owner’s manual for the exact location).
Remove the ABS fuse using a fuse puller or needle-nose pliers.
Inspect the fuse; if blown, replace it with a new one of the same amperage.

3. Clean or Replace Wheel Speed Sensors

Identify the location of each wheel speed sensor (usually near the wheel hub).
Remove the sensor by unscrewing the mounting bolt.
Clean the sensor and its connector with electrical contact cleaner.
If damaged, replace the sensor with a new one and reattach it securely.

4. Inspect ABS Control Module Wiring

Visually inspect the wiring harness connected to the ABS control module.
Look for frayed wires, loose connections, or corrosion.
Repair or replace damaged wiring as necessary.

5. Reconnect Battery and Test

Reconnect the battery terminals securely.
Start the vehicle and check if the ABS warning light has turned off.
If the light remains on, further diagnostics may be required.
