Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, brake fluid, clean rags.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Retrieve and Interpret Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Retrieve any ABS-related error codes and record them for analysis.

3. Inspect and Replace Faulty Components

Brake Fluid Level:
- Open the hood and locate the brake fluid reservoir.
- Check the fluid level; if low, top off with the recommended brake fluid type (DOT 3 or DOT 4).
Wheel Speed Sensors:
- Raise the vehicle using a jack and secure it with jack stands.
- Locate each wheel speed sensor on the wheel hub assembly.
- Disconnect the sensor connector and use a multimeter to test resistance; replace if out of specification.
ABS Relay and Fuse:
- Locate the fuse box and identify the ABS fuse using the diagram on the fuse box cover.
- Remove the fuse and inspect it; replace if blown.
- If the relay is suspected, remove it and test it with a multimeter; replace if it fails the test.

4. Reassemble and Restore

After replacing any faulty components, ensure all connections are secure.
Lower the vehicle back to the ground and check the fluid level one more time.

5. Clear Codes and Test Drive

Use the OBD-II scanner to clear the ABS codes.
Start the vehicle and perform a test drive to confirm that the ABS light does not reappear.
