System Operation: Prove-Out
The IPC and other vehicle modules carry out a display prove-out to verify all module controlled warning/indicator lamps and monitored systems are functioning correctly within the IPC. The IPC and other modules, such as the RCM, provide a timed prove-out while other indicators illuminate until engine start up. When the ignition is cycled to on with the engine off, the indicators illuminate to prove-out according to the following table:
