Solution

1. Preparation

Gather necessary tools and parts for the repair.
Disconnect the negative battery terminal to prevent any electrical issues while working on the ABS system.

2. Check ABS Fuses and Relays

Locate the fuse box and remove the cover.
Use the diagram on the cover to identify the ABS fuse and relay.
Use a multimeter to test the fuses for continuity.
- Tools Required: Fuse puller, multimeter
Replace any blown fuses with the correct amperage rating.

3. Inspect ABS Wheel Speed Sensors

Lift the vehicle securely using jack stands and remove the wheels to access the wheel speed sensors.
Clean the sensors with a soft cloth and inspect for physical damage.
Check the sensor gap to the tone ring; it should be within specifications.
- Tools Required: Socket set, torque wrench
Reinstall the wheels and lower the vehicle.

4. Test the ABS Module

Reconnect the battery terminal and use an OBD-II scanner to clear any existing codes.
Start the vehicle and check if the ABS and traction control lights remain illuminated.
If lights are still on, proceed to test the ABS pump by pressing the brake pedal and observing the pump operation.
- Tools Required: OBD-II scanner

5. Check Brake Fluid and Lines

Inspect the brake fluid reservoir to ensure it is filled to the recommended level.
Look for any signs of leaks in the brake lines and connections.
If leaks are found, repair or replace the affected components as necessary.
