Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to ensure safety during electrical work.
Required Tools: OBD-II scanner, multimeter, socket set, torque wrench, brake fluid.

2. Check and Replace Fuses

Locate the fuse box (refer to the owner’s manual for exact location).
Remove the cover and identify the ABS fuse.
Use a multimeter to test for continuity.
- If the fuse is blown, replace it with a new fuse of the same amperage.
Reconnect the fuse box cover.

3. Inspect Wheel Speed Sensors

Raise the vehicle using a jack and secure it on jack stands.
Locate the ABS wheel speed sensors at each wheel hub.
Inspect the wiring harness for frays or disconnections.
Clean any debris from the sensor surfaces.
If a sensor is damaged, replace it with a new one.

4. Check Brake Fluid and System

Remove the brake fluid reservoir cap.
Inspect the fluid level; if low, top off with manufacturer-recommended brake fluid (usually DOT 3 or DOT 4).
Inspect for leaks in brake lines and connections.
If the fluid is contaminated, perform a complete brake fluid flush.

5. Test ABS Pump and Module

Reconnect the battery and use the OBD-II scanner to clear any error codes.
Conduct a functionality test on the ABS system using the scanner.
If issues persist, consult a repair manual for specific testing procedures for the ABS pump and module.
