Door Ajar Warning

The radio receives a class 2 message from the instrument panel cluster (IPC) in order to activate a continuous, medium rate chime. The appropriate door ajar message illuminates in the driver information center (DIC) and the audible warning is activated when the following occurs:

• The IPC receives a class 2 message from the driver door module (DDM) indicating that a door is open. The signal circuit is low.
• The vehicle speed is greater than 4.8 km/h (3 mph). The IPC uses the vehicle speed signal circuit from the powertrain control module in order to calculate the vehicle speed.
