Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off and the parking brake engaged.
Disconnect the negative battery terminal to prevent electrical shocks.

2. Inspect and Replace ABS Wheel Speed Sensors

Tools Required: Socket set, multimeter, torque wrench
Locate the wheel speed sensors at each wheel hub.
Use a socket set to remove the bolts securing the sensor.
Disconnect the electrical connector and inspect for corrosion or damage.
If faulty, replace the sensor with a new one, ensuring it is properly torqued to manufacturer specifications.

3. Check and Replace ABS Fuse

Tools Required: Fuse puller or needle-nose pliers
Locate the vehicle's fuse box (usually in the engine compartment or under the dashboard).
Identify the ABS fuse using the diagram on the fuse box cover.
Remove the fuse and inspect it for continuity. Replace if blown.

4. Inspect ABS Control Module

Tools Required: Socket set, multimeter
Locate the ABS control module, usually mounted near the brake master cylinder.
Check for electrical connections and harness integrity.
If the module shows signs of failure, it may need to be replaced. Follow manufacturer guidelines for installation.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and check if the ABS warning light is still illuminated.
