It is responsible for detecting objects in front of the vehicle and warning the driver if they are too close. If the sensor is faulty, it may not be able to detect objects properly, which could lead to the front assist system not working.

2. Faulty Front Assist Control Unit

The front assist control unit is a computer that is responsible for processing the data from the front assist sensor and taking action if necessary. If the control unit is faulty, it may not be able to process the data correctly, which could lead to the front assist system not working.

3. Faulty Wiring

The front assist system is a complex system that involves a number of wires. If any of the wires are damaged or disconnected, it could prevent the system from working properly.
