Is ACC the Ignition Switch?

[LeAriel]

ACC is part of the ignition switch, which has four positions: START, ON, ACC, and LOCK. Below is an introduction to ACC: 1. ACC stands for Adaptive Cruise Control, which is a power supply controlled by the car key, generally used to power devices such as the car audio system. 2. The Adaptive Cruise Control system is an intelligent automatic control system. During vehicle operation, the distance sensor (radar) installed at the front of the vehicle continuously scans the road ahead, while the wheel speed sensor collects speed signals. 3. Typically, when the vehicle is parked and turned off, the key is in the LOCK position. In this position, the vehicle's circuits are disconnected, the entire vehicle is powered off, and the steering wheel lock is engaged. When the key is in the ACC position, some electrical devices in the vehicle, such as the radio and audio system, are powered on, but other components remain unpowered. When the key is in the ON position, all components of the vehicle, including the engine system, are powered on. START is the ignition position; once the key is turned to the START position, the starter motor is powered on and begins to operate.
