Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the vehicle battery to ensure safety while working on the electrical system.

2. Inspect and Replace ABS Fuse/Relay

Sub-steps:
1. Locate the fuse box and identify the ABS fuse and relay.
2. Remove the ABS fuse and inspect for continuity using a multimeter.
3. If blown, replace with the same amperage fuse.
4. Test the relay by swapping with a similar relay in the fuse box; replace if faulty.

3. Service Brake Fluid

Sub-steps:
1. Check the brake fluid reservoir; if low, top off with the manufacturer-recommended brake fluid type (usually DOT 3 or DOT 4).
2. If fluid is contaminated or old, perform a brake fluid flush to ensure proper operation of the ABS system.

4. Clean or Replace Wheel Speed Sensors

Sub-steps:
1. Locate the wheel speed sensors at each wheel hub.
2. Disconnect the sensor wiring harness.
3. Clean the sensor and mounting area with brake cleaner to remove debris.
4. If damaged, replace the sensor with a new one, ensuring proper torque specifications are followed.

5. Test ABS System

Sub-steps:
1. Reconnect the battery and start the vehicle.
2. Use the OBD-II scanner to clear any ABS fault codes.
3. Conduct a test drive to verify the ABS light is off and the system is functioning properly.
