Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent any electrical shorts.

2. Inspect and Replace Wheel Speed Sensors

Tools Required: Socket set, multimeter, torque wrench
Locate the ABS wheel speed sensors on each wheel hub.
Remove the sensor mounting bolts and disconnect the electrical connector.
Inspect the sensor for dirt or damage; clean or replace as necessary.
If replacing, install the new sensor, connect the electrical connector, and secure it with bolts to the manufacturer’s torque specifications.

3. Check and Replace ABS Module (if needed)

Tools Required: Socket set, brake line wrench
If diagnostic codes indicate an ABS module failure, locate the ABS control module.
Disconnect the wiring harness and brake lines connected to the module.
Unbolt the module from its mounting bracket.
Install the new module by reversing the removal steps, ensuring all connections are tight and properly torqued.

4. Restore Brake Fluid and Reconnect Battery

Check the brake fluid level in the master cylinder reservoir and top off with the appropriate brake fluid type (usually DOT 4 or DOT 3).
Reconnect the negative battery terminal securely.

5. Clear Codes and Test Drive

Use the OBD-II scanner to clear any stored ABS fault codes.
Conduct a test drive to ensure the ABS system is functioning properly.
