Key In Ignition Reminder

The instrument panel Integration Module (IPM) receives a discrete key-in-ignition signal input. The driver door module (DDM) receives a discrete LH front door jamb switch signal input. The rear integration module (RIM) receives the key-in-ignition status from the IPM and LH front door status from the DDM via a class 2 serial data messages. The RIM sends a class 2 serial data message requesting the radio to activate a medium rate multiple chime when all of the following conditions occur:
^ The ignition switch is OFF.
^ The LH front door is open.
^ The key is in the ignition.
