Final answer:
The amber ADR FAULT light indicates a fault in the Acceleration, Deceleration, and Rate control system of a vehicle.
Step-by-step explanation:
The amber ADR FAULT light indicates a fault in the Acceleration, Deceleration, and Rate control system of a vehicle. This system is responsible for managing the acceleration and deceleration of the vehicle, as well as controlling its speed.
When the amber ADR FAULT light is illuminated, it means that there is a problem with one or more components of the acceleration, deceleration, and rate control system. This could be a fault in the sensors, actuators, or other components that are involved in controlling the vehicle's speed.
For example, if there is a fault in the vehicle's throttle position sensor, it may not be able to accurately determine the position of the throttle, resulting in improper control of the vehicle's acceleration. In such cases, it is important to have the vehicle diagnosed and repaired by a qualified mechanic to ensure safe and proper functioning.
