System Operation: Prove-Out

WARNING: This page is about a different car, the 2017 Lincoln Navigator and 2017 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.

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:
