Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface, and set the parking brake.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Repair Wiring

Examine the wiring harness leading to the ABS module and wheel speed sensors.
Tools Required: Wire strippers, electrical tape, multimeter
Repair any damaged wires by splicing with new wire and insulating with electrical tape.

3. Check and Replace Faulty Components

If any wheel speed sensors are found to be damaged during testing:
1. Remove the wheel corresponding to the faulty sensor.
2. Disconnect the sensor connector.
3. Remove the old sensor and install a new one, ensuring it is seated properly.
4. Reconnect the sensor and wheel.
If the ABS module is faulty:
1. Disconnect all electrical connectors from the ABS module.
2. Remove any mounting bolts securing the ABS module to the vehicle.
3. Replace the ABS module with a new or refurbished unit.
4. Reconnect all connectors and secure the module with bolts to the specified torque.

4. Reconnect Battery and Clear Codes

Reconnect the battery terminal.
Use the OBD-II scanner to clear the C1000 code and any other related codes.

5. Test Drive

Conduct a test drive to ensure that all systems are functioning correctly and that no warning lights reappear.
