Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect Wheel Speed Sensors

Remove the wheel and tire assembly to gain access to the wheel speed sensors.
Check the sensor for any debris or foreign objects obstructing it.
Clean the sensor area with a soft cloth and brake cleaner if needed.

3. Replace Faulty Wheel Speed Sensor

If a sensor is found to be faulty during testing, proceed with replacement:
- Locate the wheel speed sensor connector and disconnect it.
- Remove the mounting bolt(s) securing the sensor.
- Carefully pull the sensor out of its mounting position.
- Install the new sensor by reversing the removal steps and ensuring it is securely fastened.

4. Reconnect Electrical Connections

Reconnect the connector to the new wheel speed sensor.
Ensure all wiring is properly secured and free of damage.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and allow it to idle for a few minutes.
Take the vehicle for a test drive to ensure ABS functionality is restored and the C1241 code is cleared.
