Speed Control (Service Information): Description: Adaptive

The Adaptive Cruise Control (ACC) system is an electronically controlled driver assistance system which combines the cruise control functions with a function for monitoring the distance from the vehicle ahead to keep the vehicle at a set speed and distance without needing to touch the brake and accelerator pedals (the distance can be set by the driver using the specific switch).

The ACC uses a radar sensor, located in the front fascia grille and a Forward Facing Camera (FFC) located in the top middle of the windshield to detect the presence of a vehicle ahead.

The Steering Wheel Switches (SWS) control requests are sent to the Body Control Module (BCM) via the Local Interface Network (LIN). The BCM translates the messages received and sends them to the Instrument Panel Cluster (IPC), Transmission Control Module (TCM) and the Anti-Lock Brake System (ABS) via the Controller Area Network (CAN).

Once the ACC functions activate their specific strategies, The Powertrain Control Module (PCM) will operate to hold the set speed and distance set by the driver.

There are four different operating states for the device:

• ON (speed not set)
• Activated (set speed)
• Pausing
• OFF
