RTT Indicators

Auto Stop-Start (China Only) 

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-CAN1. The GWM receives the stop/start message request from the PCM over the HS-CAN3.

Auto Hold 

The message center provides the auto hold RTT indicator to indicate to the driver the state of the auto hold feature. The auto hold feature holds a vehicle stationary once the vehicle has come to a stop using the brakes, allowing the driver the convenience of removing his or her foot from the brake pedal. The IPC receives the auto hold mode indicator request message from the GWM over the HS-CAN3. The GWM receives the auto hold mode indicator request message from the ABS module over the HS-CAN2.

Charging System 

The IPC provides a charging system RTT indicator along with message displays indicating the status of 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 RTT 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:

• Cruise control status
• Cruise control set speed
• Cruise control override

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 RTT 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 over-temperature message from the PCM over the HS-CAN1.

Low Fuel 

To supplement the fuel gauge indication, the IPC provides the low fuel RTT 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 RTT 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.

Low Washer Fluid Level 

The low washer fluid level switch is hardwired to the IPC through a single signal circuit and is grounded through a separate ground circuit. The IPC provides a reference voltage to the washer fluid level switch. When the washer fluid is low, the washer fluid level switch closes to ground, pulling the reference voltage low. When the IPC detects the washer fluid input pulled low and illuminates the low washer fluid level RTT warning 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 GSM service required message from the GSM over the HS-CAN2.

The GWM receives the transmission service required, engine service required and the AWD service required messages from the PCM (without torque vectoring differential) or AWD module (with torque vectoring differential) over the HS-CAN1.
