Solution

1. Preparation

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

2. Scan for Codes

Use an OBD-II scanner to retrieve ABS fault codes.
Document any codes displayed for reference.

3. Inspect ABS Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Clean any debris or dirt from the sensor area.
Check the sensor wiring for damage or loose connections; repair or replace as necessary.

4. Check Brake Fluid Levels

Remove the cap from the brake fluid reservoir.
Check fluid level; if low, top off with the manufacturer-recommended brake fluid (usually DOT 3 or DOT 4).
Inspect for leaks in the brake lines and around the master cylinder.

5. Inspect ABS Module and Wiring

Visually inspect the ABS module for signs of corrosion or damage.
Check the wiring harness connected to the ABS module for fraying or loose connections.
Repair or replace damaged wiring as needed.

6. Clear Codes and Test

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored ABS error codes.
Test drive the vehicle to verify proper operation of the ABS system.
