Active Park Assist System
The active park assist system detects available parking space and automatically steers the vehicle in the parking space without the driver touching the steering wheel. The driver controls the accelerator, transmission selection and the vehicle brakes. The system visually and/or audibly instructs the driver throughout the procedure to safely park the vehicle. The PAM controls the active park assist system. The system uses 2 long range ultrasonic sensors that are hardwired to the PAM to detect the available parking space for the vehicle. The PAM uses the HS-CAN to send and receive network messages to control the active park assist system. Refer to ACTIVE PARK ASSIST for active park assist information.
Network Communication
Note. Both the MS-CAN and the HS-CAN are used for intermodule communication. A gateway message is transferred from one network to another network through the Instrument Cluster (IC). For a complete list of Controller Area Network (CAN) multiplex messages, Refer to MODULE COMMUNICATIONS NETWORK .
