System Operation: Startup-Shutdown

The IPC  provides a startup/shutdown sequence also known as a welcome/farewell strategy. When the vehicle receives a RKE  request or a door ajar (open) message, the IPC  illuminates the gauge trim rings and pointers. When the ignition is placed in the ACC mode, all cluster backlighting, gauges and indicators are turned off. When the ignition is placed into the RUN or START mode, the IPC  begins a prove-out stage. During the prove-out stage, the IPC  illuminates all LED indicators for a predetermined time and provides message center information. For the shutdown, the IPC  reverses the startup process.
