Odometer

The IPC receives the odometer count message from the PCM over the HS-CAN . The IPC monitors the odometer count input from the PCM and commands the odometer with a digital display in the integrated LCD , located in the center of the IPC .

One-Touch Integrated Start Displays

The message center provides message displays indicating the status of the one-touch integrated start system. The IPC receives the one-touch integrated start status message from the PCM over the HS-CAN and send it to the FDIM through the APIM over the Infotainment Controller Area Network (I-CAN) or to the FCDIM over the Infotainment Controller Area Network (I-CAN).

Outside Air Temperature Display

The Ambient Air Temperature (AAT) sensor is hardwired to the IPC through separate input and return circuits. The IPC provides a reference voltage to the Ambient Air Temperature (AAT) sensor and monitors the change in voltage resulting from changes in resistance as determined by outside air temperature. The IPC filters the ambient air temperature input and sends the outside air temperature data message to the FDIM through the APIM over the Infotainment Controller Area Network (I-CAN) or to the FCDIM over the Infotainment Controller Area Network (I-CAN). The IPC is programmed to update the displayed temperature at different rates depending on several criteria to prevent false temperature displays due to a condition known as heat soaking. Heat soaking is where the outside air temperature is hotter in the location of the Ambient Air Temperature (AAT) sensor than the actual outside air temperature.

The IPC uses the last displayed temperature reading, engine coolant temperature and length of time the engine is off to determine how the display is updated. The IPC stores the last temperature reading at key off and then compares the value against the current temperature reading. When the current temperature reading is below the stored temperature reading, the engine has been off for 2.5 hours or the engine coolant temperature is below 45°C (32°F), the IPC displays the current outside air temperature as measured by the Ambient Air Temperature (AAT) sensor.

If the IPC fails any of the above criteria, the display is updated according to the following table:




Vehicle Speed Display Update Rate (Per Minute)
Below 32 km/h (20 mph) 0.05°C (0.09°F)
Between 32 km/h (20 mph) and 80 km/h (50 mph) 1.0°C (1.8°F)
Between 80 km/h (50 mph) and 120 km/h (75 mph) 1.5°C (2.7°F)
Above 120 km/h (75 mph) 2.0°C (3.6°F)


Passive Entry With Push Button Start Displays

The message center provides message center displays indicating the status of the vehicle's passive entry with push button start system status. The IPC receives the passive key message request message from the RFA over the MS-CAN and sends it to the FDIM through the APIM over the Infotainment Controller Area Network (I-CAN) or to the FCDIM over the Infotainment Controller Area Network (I-CAN).

PRNDL Display

The IPC receives the transmission gearshift lever position message from the TCM over the HS-CAN . The IPC uses the factory mode and transport mode status, controlled internally, to reduce the battery drain during build and extended periods of time when the vehicle is not in use. The IPC also uses a park position detect switch (part of the selector lever) hardwired input to signal the IPC the shift lever is fully seated in the PARK (P) position. The IPC compares the park position detect switch input with the transmission gear display message sent from the TCM .

Stability-Traction Control System Displays

The message center provides a stability-traction control system message indicating the traction control is disabled. When fault conditions exist such as wheel speed sensor failure, control valve failures, communication failures or low battery voltage in the ABS , the ABS module sends a brake warning request message to the IPC over the HS-CAN to illuminate the ABS warning indictor. The IPC sends the stability-traction control indicator request to the FDIM through the APIM or FCDIM over the Infotainment Controller Area Network (I-CAN) to display the stability-traction control message in the message center.

SRS Indication Displays

The message center provides a display indicating a SRS failure. The IPC receives the airbag malfunction message from the RCM over the HS-CAN and sends it to the FDIM over the Infotainment Controller Area Network (I-CAN) or to the FCDIM over the Infotainment Controller Area Network (I-CAN).

Transmission Displays

The message center provides message center displays indicating transmission malfunctions, transmission range selector status and required driver operations (shift to park). The IPC receives the transmission warning indicator request and gearshift lever message request messages from the TCM over the HS-CAN . The IPC sends the transmission warning indicator request and gearshift lever message request messages to the FDIM through the APIM over the Infotainment Controller Area Network (I-CAN) or to the FCDIM over the Infotainment Controller Area Network (I-CAN).

TPMS Displays

The message center provides messages indicating TPMS malfunction, tire pressure sensor faults, low tire pressures and tire training. The IPC receives the TPMS message request messages from the BCM over the MS-CAN and sends them to the FDIM through the APIM over the Infotainment Controller Area Network (I-CAN) or to the FCDIM over the Infotainment Controller Area Network (I-CAN).
