IPC Power, Ground, and Class 2
The IPC receives battery positive voltage from the underhood junction block IP fuse circuit. The IPC receives ignition voltage (ACC and ON) from the rear junction block IGN1 fuse circuit.
The IPC receives all class 2 messages, via the class 2 serial data line.
Important: The IPC receives ignition status from the Dash Integration Module (DIM), via the class 2 serial data line. If the IPC can not communicate with the DIM, the IPC will not operate properly.
The IPC ground location is at G200.
