Driver/Vehicle Information Display: Description and Operation
RIGHT REAR DOOR AJAR (143)
The RH Rear Door Module (RRDM) receives a discrete input from the RH rear ajar switch. The IPC receives the status of the RH rear door from the
RH rear door module (RRDM) via class 2 serial data message. When the RH rear door is open and the vehicle is out of the PARK gear, the IPC displays
the message. Also, if the vehicle speed is greater than 4.8 km/h (3 MPH), the IPC displays the message and sends a class 2 serial data message
requesting 5 chimes to sound.
