Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a level surface and the ignition is off.
Tools Required: OBD-II scanner, socket set, multimeter, brake fluid, wire brush, and cleaning solution.

2. Check and Refill Brake Fluid

Open the hood and locate the brake fluid reservoir.
If the fluid is low, clean the reservoir cap and add the appropriate brake fluid (DOT 3 or DOT 4 as per the owner’s manual).
Ensure that there are no leaks in the brake lines or connections.

3. Inspect and Replace ABS Wheel Speed Sensors

Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the ABS wheel speed sensor.
Disconnect the sensor harness and remove the sensor using a socket wrench.
Inspect the sensor for damage. If damaged, install a new ABS wheel speed sensor in reverse order of removal.
Reconnect the harness securely.

4. Check ABS Module and Wiring

Inspect the wiring harness connected to the ABS module for any signs of wear, corrosion, or disconnection.
If necessary, clean the connections with a wire brush and electrical contact cleaner.
Reconnect any loose connections and ensure they are tight.

5. Clear Error Codes

Use the OBD-II scanner to clear any stored ABS error codes after completing the repairs.
Start the vehicle and check if the ABS light remains off.
