Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shocks.

2. Address Error Codes

Use the OBD-II scanner to clear any stored ABS error codes after repairs are made.
If codes return, note them for further diagnosis.

3. Check and Replace Fuses

Locate the fuse box (usually under the dashboard or hood).
Use a multimeter to test the ABS fuse for continuity.
If blown, replace with the same amperage fuse.

4. Inspect and Clean Wheel Speed Sensors

Raise the vehicle using a jack and secure it with jack stands.
Locate each wheel speed sensor near the brake rotor.
Clean the sensor and surrounding area with a soft cloth and brake cleaner.
Ensure the sensor connector is securely attached.

5. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Ensure the fluid level is between the minimum and maximum marks.
If low, top up with manufacturer-recommended brake fluid (DOT 3 or DOT 4).

6. Inspect ABS Module and Wiring

Visually inspect the ABS module and its wiring harness for any signs of damage.
If necessary, repair any damaged wires or connectors.
Ensure all connections are tight and free of corrosion.

7. Reassemble and Test

Reconnect the negative battery terminal.
Start the vehicle and observe the dashboard for the ABS light.
Test drive the vehicle to ensure the ABS system is functioning properly.
