Message Displays

Blind Spot Monitoring System (BLIS ®)/Cross Traffic Alert (CTA)

The IPC receives the BLIS on, cross traffic alert - left and cross traffic alert - right messages from the BCM over the MS-CAN. The BCM receives the BLIS on, cross traffic alert - left and cross traffic alert - right messages from the SODL over the extended MS-CAN.

Brake System 

The IPC provides brake system messages for the following concerns and status:

• low brake fluid level
• parking brake applied status
• ABS concerns that display along with the brake warning indicator operation

When the parking brake is applied, the BCM sends the park brake warning request to the IPC over the MS-CAN to illuminate the brake warning indicator and display the parking brake applied message in the message center.

When a low brake fluid level condition exists, the BCM sends the brake fluid level warning request to the IPC over the MS-CAN to illuminate the brake warning indicator and display the brake fluid level low message in the message center.

When an ABS concern exists, the ABS module sends the brake warning indicator request message to the GWM over the HEV - CAN. The GWM sends the brake warning indicator request message to the IPC over the MS-CAN to illuminate the ABS warning indictor and to display the check brake system warning message in the message center.

Charging System 

The IPC provides a message center warning message to indicate a fault in the the base charging system. The IPC receives the power system status message from the BCM over the MS-CAN to illuminate the charging system RTT warning indicator.

Door/Liftgate Ajar 

The IPC provides message center warnings to indicate the status of the doors or liftgate. The BCM monitors each of the ajar inputs and sends a door status message to the IPC over the MS-CAN to display the specific ajar warning message.

Engine/Motor Over-Temperature 

The IPC provides warning messages to supplement the engine/motor over-temperature RTT indicator and alert the driver the engine or motor is over-temperature. The IPC uses the following messages to display the engine/motor over-temperature warning messages.

Fuel System 

The IPC provides a check fuel fill inlet message to warn the driver there is a problem with the fuel fill inlet pipe resulting in a significant evaporative emission leak following vehicle refueling.

On plug-in hybrid vehicles, the IPC provides a message to inform the driver the engine needs to run to maintain fuel freshness and a message to inform the driver the fuel door is locked shut until the fuel evaporative emissions system equalizes pressure. This is to prevent rapid equalization since the fuel system can be under emissions-related vacuum or pressure during operation. The warning provides the reason the fuel door is locked while the fuel system gradually equalizes.

The IPC receives the check fuel fill inlet message request, the refuel system status display and the fuel maintenance mode display messages from the GWM over the I-CAN.

The GWM receives the check fuel fill inlet message request and the refuel system status display message from the PCM over the HEV - CAN.

MyKey ® Function 

The IPC provides message center displays for the MyKey ® feature. MyKey ® displays are controlled through the IPC software based on the MyKey ® settings configured through the message center and the type of key in use (MyKey ® or administrator key). The MyKey ® function also uses other messages received by the IPC for other indication such a vehicle speed for speed limiter displays.

Oil Life/Maintenance 

The IPC provides message center messages to inform the driver the oil life has reached its limit and requires changing. The IPC also provides message center messages to inform the driver of the reason the engine is running resulting from the oil maintenance strategy for the plug in hybrid vehicle.

The message center provides an oil change minder to inform the driver that an oil change is required. The duration of the interval between oil changes is calculated in the PCM and varies due to driving conditions. The PCM assumes a base mileage of 16, 090 km (10, 000 mi) or 1 year for normal driving. However, this number is adjusted down for conditions such as high engine temperature, high engine rpm, use of flex fuel and possibly low oil level.

The oil maintenance mode for the plug in hybrid vehicles runs the engine for approximately 15 minutes to maintain engine oil integrity during long intervals when the engine is not used. The IPC provides message center message displays to inform the driver of the reason the engine is running.

The IPC receives the engine oil change minder messages from the BCM over the MS-CAN. The BCM receives the engine oil change minder message from the GWM over the High Speed Controller Area Network (HS-CAN). The GWM receives the engine oil change minder message from the PCM over the HEV - CAN.

The IPC receives the engine on oil maintenance message display message from the GWM over the I-CAN. The GWM receives the engine on oil maintenance message display message from the SOBDMC over the HEV - CAN.

Parking Aid System 

The IPC provides messages to indicate the status of the parking aid system. The IPC receives the active parking aid status, the parking aid status and the parking aid fault messages from the BCM over the MS-CAN. The GWM receives the parking aid status and the parking aid fault messages from the PAM over the High Speed Controller Area Network (HS-CAN).

• A steering lock fault exists
• Accessory power is active
• Key is in the backup slot
• Key is in the luggage compartment
• Key is left in the vehicle

Shift To Park 

The IPC provides a shift to park message to inform the driver the vehicle is not in PARK (P) under 2 sets of conditions. First, the IPC displays the shift to park message if the selector lever is not in PARK (P), the ignition is OFF and the driver door is open or ajar. Second, the IPC displays the shift to park message if the selector lever is not in PARK (P), the ignition is ON or in ACC, the driver door is open or ajar and the brake pedal is not applied with vehicle speed less than 5 km/h (3 mph). The IPC uses the following messages to control the shift to park message.

Transport Mode Display 

During vehicle build, some modules, such as the IPC and the BCM, are set in factory mode. While in the factory mode the IPC displays FACTORY MODE CONTACT DEALER in the message center. If the vehicle is set in factory mode, the system does not automatically exit the mode and must be manually set to either the transport or normal operation mode.

When the vehicle build is complete, the vehicle is set to transport mode. While in transport mode, the IPC displays TRANSPORT MODE CONTACT DEALER in the message center. Transport mode is used to reduce the drain on the battery during longer periods where the vehicle is not used. Various systems may be altered or are disabled when in the transport mode. The vehicle automatically reverts to normal operation mode after being driven 201 km (125 mi).

The IPC receives the vehicle mode message from the BCM over the MS-CAN.
