Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Replace ABS Fuse

Locate the fuse box under the dashboard or engine bay (refer to owner’s manual for exact location).
Remove the ABS fuse using a fuse puller or pliers.
Inspect the fuse; replace it if it is blown with a new fuse of the same amperage.

3. Check and Refill Brake Fluid

Locate the brake fluid reservoir.
Remove the cap and check the fluid level.
If the fluid is low, add the recommended brake fluid (typically DOT 3 or DOT 4) to the appropriate level.
Secure the cap back on the reservoir.

4. Inspect ABS Wheel Speed Sensors

Raise the vehicle using a jack and secure it with jack stands.
Locate the ABS wheel speed sensors at each wheel hub.
Check for any physical damage or dirt obstructing the sensor.
If damaged, remove the sensor by unscrewing it and replace it with a new one.

5. Examine ABS Module Connections

Follow the wiring from the ABS module to each wheel.
Inspect for broken or frayed wires; repair or replace as necessary.
Ensure all connectors are fully seated and free from corrosion.

6. Reconnect Battery and Reset ABS System

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored ABS codes and reset the system.
Test the vehicle to ensure the ABS light is off and the system is functioning properly.
