Solution

1. Preparation

Gather tools and parts needed for repair.
Disconnect the negative battery terminal to prevent electrical shorts.
Gather safety equipment (gloves, goggles).

2. Inspect and Clean Wheel Speed Sensors

Sub-steps:
- Locate the wheel speed sensors on each wheel hub.
- Remove any dirt or debris from the sensor and surrounding area using a clean cloth.
- If sensors are damaged, remove and replace them.
Tools Required: Socket set, cleaning cloth.

3. Check Wiring and Connectors

Sub-steps:
- Visually inspect the wiring harness for any signs of fraying or disconnection.
- Use a multimeter to check for continuity in the wiring.
- Repair or replace any damaged wires or connectors.
Tools Required: Multimeter, wire repair kit.

4. Test Brake Pedal Switch

Sub-steps:
- Locate the brake pedal switch, typically mounted above the brake pedal.
- Use a multimeter to test the switch for continuity when the brake pedal is pressed.
- Replace the switch if it is defective.
Tools Required: Multimeter, socket set for removal.

5. ABS Module Function Check

Sub-steps:
- Reconnect the battery and use the OBD-II scanner to perform an ABS module function test.
- If the ABS module fails the test, replace the ABS module.
