System Operation: Configuration

The IPC contains items that are configurable. Configurable items include customer preference items, which can also be set with a scan tool. The remaining configurable items can only be set through the PMI procedure by uploading/downloading existing configuration or by using As-Built data. Refer to the scan tool instructions.

Dealer Test Mode

To enter the IPC self-diagnostic mode, begin with the ignition in the OFF mode. Press and hold the LH steering wheel switch OK button (base IPC). Place the ignition in the ON mode and hold the button until the display indicates ENGINEERING TEST MODE, usually within 3 to 5 seconds. Press the up or down arrow buttons to navigate through each of the display windows. To exit the IPC self-test mode, press and hold the OK button for 3-5 seconds or place the ignition in the OFF mode. The dealer test mode displays multiple items in a viewing window on the RH side of the IPC. Each button press advances the viewing window to the next set of items.

NOTE: All message center warnings and pop-up displays need to be addressed to enter the dealer test mode.

NOTE: Some of the displays listed in the table below use xxx's to represent a numeric or alphanumeric value. The value may display the same amount of characters represented by the xxx's or there may be more/less depending on the type of display. For example: DTC HIST CURR xxxxxx x x may display DTC HIST CURR C10000 X. Note that there were 8 x's in the display description but only 7 digits in the actual display.

Factory-Transport Mode

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 80 km (50 mi). Refer to Multifunction Electronic Modules for the Transport Mode Deactivation.

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

Gateway Function

The IPC acts as a gateway module by receiving information through the HS-CAN and converting and transmitting it to the audio and multimedia modules using the I-CAN.

MyKey ®

The MyKey ® feature allows the customer to program a restricted driving mode that is tied to one or more keys known as a MyKey ® key. The following features are provided by the IPC when a MyKey ® key is being used:

At the beginning of vehicle start up, as part of the welcome strategy, the message center greets the MyKey ® driver with MYKEY ACTIVE DRIVE SAFELY displayed in the message center. If the MyKey ® speed limiter feature is turned on, the message center also displays the MyKey ® administrator selected top speed setting message; SPEED LIMITED TO XX MPH (km/h). The MyKey ® top speed selections are; 105, 110, 120 or 130 km/h (65, 70, 75, or 80 mph) or to the administrator desired setpoint.
The IPC provides a periodic Belt-Minder ® warning chime until the driver and passenger safety belts are buckled. When the Belt-Minder ® is issued, the ACM is muted and the message center displays BUCKLE UP TO UNMUTE AUDIO.
If the MyKey ® speed limiter feature is turned on and the vehicle speed approaches the selected top speed (105, 110, 120 or 130 km/h [65, 70, 75, or 80 mph]), the message center displays NEAR VEHICLE TOP SPEED along with a chime.
If the MyKey ® speed limiter feature is turned on and the vehicle speed reaches the selected top speed (105, 110, 120 or 130 km/h [65, 70, 75, or 80 mph]), the message center displays VEHICLE AT TOP SPEED OF MYKEY SETTING along with a chime.
If the speed warning is selected at one of the preset values (75, 90, 105 km/h [45, 55, 65 mph]) and the vehicle approaches the preset speed, the message center displays CHECK SPEED DRIVE SAFELY along with a chime.
At approximately 1/8 tank of remaining fuel, the IPC illuminates the low fuel message center indicator and the message center displays FUEL LEVEL LOW along with a chime.
Traction control emergency 911 Assist ® feature and the Do Not Disturb feature can be set to always on or user selectable in the MyKey ® menu.
If the traction control always on feature is turned on and the MyKey ® driver attempts to disable the traction control, the message center displays ADVANCETRAC ON MYKEY SETTING.
MyKey ® miles driven by the MyKey ® user can be found in the information display.
The number of MyKey ® programmed and administrator keys can be found in the MyKey ® menu.
The parking aid, BLIS ® /CTA, lane departure alert and collision avoidance warning menus are disabled in the message center to force these features always on.

When an administrator key is in use, the IPC provides:

a menu in the message center guiding the user to create a MyKey ®. When the maximum MyKey ® limit is reached, the MyKey ® creation menu is no longer available.
a menu in the message center with options for setting 6 optional MyKey ® features:
- MyKey ® speed limiter
- MyKey ® preselected speed warning
- MyKey ® radio volume limiter
- traction control always on or user selectable
- emergency 911 Assist ® feature always on or user selectable
- do not disturb feature always on or user selectable
a menu to clear all MyKey ® programmed keys at once.
MyKey ® mileage driven by the MyKey ® user in system check function of the message center.
the number of MyKey ® programmed keys and administrator keys in the system check function of the message center.

For information on the MyKey ® features, refer to the Owner's Literature.

Networked Input Messages and Default States

The IPC uses input messages from other modules to control the gauges, informational indicators, and warning indicators over the communication networks. All messaged inputs required by the IPC are received over the HS-CAN. If a required message is missing or invalid for less than 5 seconds, the gauge or indicator that requires the message remains at the last commanded state based upon the last message received. For example, if the stability/traction control status message is missing for less than 5 seconds and the stability/traction control indicator (sliding car icon) was on, the indicator remains on until the next message is received. If the message remains missing or invalid for more than 5 seconds, the IPC sets a U-code DTC and the IPC output becomes a default action for the indicator or gauge. Each indicator or gauge utilizes a different default strategy depending on the nature of the indication. Refer to the diagnostic overview descriptions located before each individual pinpoint test for further description of the default action specific to each indicator or gauge. If the missing messaged input to the IPC returns at any time, the normal function of the gauge or indicator resumes.

NOTE: Whenever a network message is suspected as missing and confirmed by a missing message DTC (U-code), it is important to look for other symptoms that may also be present in the IPC and throughout the vehicle. Once a DTC sets in the IPC, it may be helpful to review the complete message list. Refer to Module Communications Network , CAN Multiplex Messages to determine which other modules also rely on the same message and run the self-test for those modules. If the message is missing from other modules, the same DTC may also be set in those modules. Confirmation of missing messages common to multiple modules may indicate the originating module is the source of the concern or the communication network may be faulted.

It is very important to understand:

where the input originates.
all the information necessary for a feature to operate.
which module(s) receive(s) the input or command message.
which module controls the output of the feature.
whether the module that receives the input controls the output of the feature, or whether it outputs a message over the communication network to another module.

Prove-Out

The IPC and other vehicle modules carry out a display prove-out to verify all module controlled warning/indicator lamps and monitored systems are functioning correctly within the IPC. The IPC and other modules, such as the RCM, provide a timed prove-out while other indicators illuminate until engine start up. When the ignition is cycled to on with the engine off, the indicators illuminate to prove-out according to the following table:Prove-Out
