RTT Indicators

Auto Stop-Start 

The IPC provides the auto stop-start RTT indicator to inform the driver of the system status. The IPC receives the stop/start message request from the GWM over the HS-CAN3. The GWM receives the stop/start message request from the PCM over the HS-CAN1.

Charging System 

The IPC provides a charging system RTT indicator to indicate a fault in the charging system. When a fault is present in the charging system, the BCM sends the charging system indication request to display message center warning messages and the charging system message center warning indicator.

The IPC receives the charging system indication request message from the GWM over the HS-CAN3. The GWM receives the charging system indication request message from the BCM over the HS-CAN1.

Cruise Control 

The IPC uses the following messaged inputs to control the cruise control RTT indicator:

The IPC uses cruise control status, cruise control set speed and cruise control override messaged inputs to control the cruise control RTT indicator. When the ECO mode is active, the cruise control system allows a wider range of vehicle speed loss before accelerating to maintain the selected speed for better economy. The IPC receives the cruise control messages from the GWM over the HS-CAN3. The GWM receives the cruise control messages from the PCM over the HS-CAN1.

Door Ajar 

The IPC provides a door ajar RTT indicator to indicate the status of the doors or luggage compartment lid. The BCM monitors each of the ajar inputs and sends a door ajar status message to the GWM over the HS-CAN1. The IPC receives the door ajar status message from the GWM over the HS-CAN3 to display the specific ajar message center warning indicator and corresponding warning message.

Engine Over-Temperature 

The IPC provides a RTT warning indicator to alert the driver the engine is over temperature. The IPC receives the engine overheat indication request and the engine coolant temperature data from the GWM over the HS-CAN3. The GWM receives the engine overheat indication request and the engine over-temperature message from the PCM over the HS-CAN1.

Grade Assist 

The grade assist RTT indicator informs the driver the grade assist function is turned on and is in ready mode. The IPC receives the transmission shift mode request message from the GWM over the HS-CAN3. The GWM receives the transmission shift mode request message from the PCM over the HS-CAN1.

Low Fuel 

To supplement the fuel gauge indication, the IPC provides the low fuel message center warning indicator. When the DTE reaches less than approximately 50 km (30 miles) DTE (without MyKey ® key) or 80 km (50 miles) DTE (with MyKey ® key), the IPC turns on the low fuel message center warning indicator.

Low Oil Pressure 

The engine oil pressure switch is hardwired to the PCM. The PCM provides the engine oil pressure indicator request and engine RPM data to the GWM over the HS-CAN1. The IPC receives the oil pressure warning indicator request and engine RPM data from the GWM over the HS-CAN3. The IPC requires engine RPM above 400 RPM before the message center displays the low oil pressure RTT indicator.

Powertrain Malfunction (Wrench) 

The IPC provides a powertrain malfunction (wrench) RTT indicator to indicate transmission, Electronic Throttle Control (ETC), AWD, and BCM concerns.

The IPC receives all the required messages from the GWM over the HS-CAN3.

The GWM receives the body service required message from the BCM over the HS-CAN1.

The GWM receives the transmission service required, engine service required and AWD service required messages from the PCM over the HS-CAN1.
