Driver Door Ajar
The driver door module (DDM) receives a discrete input from the driver door
ajar switch. The integrated radio controller (IRC) receives the status of the driver
door from the driver door module (DDM) via class 2 serial data message. When
the driver door is open and the vehicle is out of the PARK gear, the driver information
center (DIC) displays the message. Also, if the vehicle speed is greater than 4.8 km/h
(3 mph), the DIC displays the message and sends a class 2 serial data
message requesting 5 chimes to sound.
Passenger Door Ajar
The passenger front door module (PDM) receives a discrete input from the passenger
front door ajar switch. The integrated radio controller (IRC) receives the status
of the passenger front door from the passenger front door module (PDM) via class 2
serial data message. When the passenger front door is open and the vehicle is out
of the PARK gear, the driver information center (DIC) displays the message. Also,
if the vehicle speed is greater than 4.8 km/h (3 mph), the DIC displays
the message and sends a class 2 serial data message requesting 5 chimes to
sound.
Left Rear Door Ajar
The LH rear door module (LRDM) receives a discrete input from the left rear
door ajar switch. The integrated radio controller (IRC) receives the status of the
LH rear door from the LH rear door module (LRDM) via class 2 serial data message.
When the LH rear door is open and the vehicle is out of the PARK gear, the driver
information center (DIC) displays the message. Also, if the vehicle speed is greater
than 4.8 km/h (3 mph), the DIC displays the message and sends a class 2
serial data message requesting 5 chimes to sound.
Right Rear Door Ajar
The RH rear door module (RRDM) receives a discrete input from the RH rear door
ajar switch. The integrated radio controller (IRC) 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 driver information
center (DIC) displays the message. Also, if the vehicle speed is greater than 4.8 km/h
(3 mph), the DIC displays the message and sends a class 2 serial data
message requesting 5 chimes to sound.
