Hardwired Inputs

The IPC requires hardwired inputs from components that are not on the CAN. These components are required for specific IPC functions.

The hardwired inputs are provided by the following components:

  • Fuel pump and sender unit
  • Low washer fluid level switch

Networked Input Messages and Default States

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 can also be present in the IPC and throughout the vehicle. Once a DTC sets in the IPC, it is helpful to review the complete message list 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 or similar lost communication DTC can also be set in those modules. Confirmation of missing messages common to multiple modules can indicate the originating module is the source of the concern or the communication network may be faulted.

For a list of all the network messages,
Refer to: Communications Network - System Operation and Component Description (418-00 Module Communications Network, Description and Operation).

The IPC uses input messages from other modules to control the gauges, informational indicators, warning indicators and message center message displays over the communication networks. The IPC receives all networked data over the HS-CAN3.

The vehicle uses 4 communication networks to transmit the data used by the IPC.

  • HS-CAN1
  • HS-CAN2
  • HS-CAN3
  • MS-CAN

For overview information,
Refer to: Communications Network - Overview (418-00 Module Communications Network, Description and Operation).

For system operation information,
Refer to: Communications Network - System Operation and Component Description (418-00 Module Communications Network, Description and Operation).

All messaged inputs to the IPC from other networks are received from the GWM over the HS-CAN3. The GWM, as the name implies, acts as a gateway to convert messages from one of the other 3 networks to the HS-CAN3, which is recognized by the IPC.

Network messages can drop out or be missing for a variety of reasons, such as high network traffic on the bus. The IPC incorporates a defined strategy for handling missing network messages based on time. The required time for a network message to be missing differs between the various gauges, indicators and message center displays. The strategy is basically the same for all indication outputs (gauges, indicators or chimes), but differs in the length of time required for the network message to be missing. If a required network message is missing or invalid for less than the programmed length of time, the gauge, indicator or message center display that requires the network message remains at the last commanded state based upon the last network message received. If the messaged input is missing for longer than the programmed length of time, the IPC output (gauge, indicator) reacts according to a pre-defined default action.

For example, if the stability-traction control indicator request network message is missing for less than 5 seconds, and the stability-traction control indicator (sliding car icon) was on, the indicator remains in the on state until the next network message is received. If the network 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. The indicator may default on/off or the gauge may default to the rest position.

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 pinpoint test for further descriptions 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, indicator or message center display resumes.

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.

Startup-Shutdown

The IPC provides a startup/shutdown sequence also known as a welcome/goodbye strategy. The IPC initiates and follows a progressive strategy providing increasing IPC functionality from IPC wake up to ready to drive status. This sequence begins at RKE unlock or driver door open through the ignition RUN state. During this period, the IPC provides increasing functionality from backlighting or illuminating gauge rings, gauge pointers, illuminating the PRND display, backlighting of the message center display, displaying a message center splash screen, gauge and indicator prove out, gauge sweep and finally normal IPC operation.

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. 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 seatbelts 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 (100, 110, 120 or 130 km/h [60, 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 TOP SPEED 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 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.

The following features are provided in the centerstack display when a MyKey® key is being used:

  • 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.

Configuration

The IPC contains items that are configurable. Some of the configurable items (configurable parameters) are customer preference items which can be set with a diagnostic scan tool. The remaining configurable items can only be set through the vehicle configuration parameters.
Refer to: Module Configuration - System Operation and Component Description (418-01 Module Configuration, Description and Operation).

Prove-Out

The IPC carries out a display prove-out to verify the gauges function and all module controlled warning indicator lamps and monitored systems are functioning correctly within the IPC. Upon initiation of the prove-out, the gauges sweep from one stop to the other then return to the normal indication state based on the input received. The IPC also provides a timed prove-out of some indicators while other indicators illuminate upon engine start up or have no prove-out. When the ignition is cycled on, the indicators illuminate to prove-out according to the following table:

Indicator Indicator Type Prove-Out Duration
Airbag Warning 6 seconds
  ABS Warning 3 seconds
Brake Warning 3 seconds
Charging system Warning 3 seconds
Distance alert Warning 3 seconds
Engine over-temperature Warning 3 seconds
Lights on (side marker position) Informational None
Low fuel Warning 3 seconds
  MIL Informational Engine start up
Rear seatbelt monitor Informational 65 seconds if the seatbelt is unbuckled, turns off when the seatbelt is buckled
Seatbelt Informational 65 seconds if the seatbelt is unbuckled, turns off when the seatbelt is buckled
Stability-traction control (sliding car icon) Warning 3 seconds

Dealer Test Mode

To enter the IPC engineering test mode or dealer test mode, begin with the ignition off. Press and hold the RH steering wheel switch OK button. Place the ignition on and continue to hold the button for 5-8 seconds until the display indicates ET. Press up or down on the toggle button to navigate through each of the display windows. To exit the IPC dealer test mode, press and hold the OK button for 5-8 seconds or place the ignition in off. Each button press advances the viewing window to the next set of items.

Gauges

AWD Gauge

The AWD gauge displays the level of power applied to each wheel independently. The AWD system is almost always active and is transferring torque whenever the vehicle is accelerating, boosting output when wheels are slipping and shutting off on the highway to conserve fuel. The IPC receives the AWD wheel lock display message from the GWM over the HS-CAN3. The GWM receives the AWD wheel lock display message from the AWD module over the HS-CAN1

As power is applied to the wheels, the area directly in front (front wheels) or rear (rear wheels) of each displayed wheel begins to fill in. The lowest power displayed is the closest to the wheel. As the amount of power sent to the wheels increases, the area fills in either forward (front wheels) or rearward (rear wheels) of the wheels.

Fuel Gauge

The IPC sends a reference voltage to the fuel level sender. As the fuel level changes, a float actuates the variable resistor fuel level sender, raising or lowering the fuel level signal voltage. The IPC monitors the changes in voltage from the fuel level sender and sends a fuel level data message to the PCM through the GWM to calculate the fuel level.

The PCM calculates the fuel level based on current fuel in the fuel tank and the tank size. The PCM sends the fuel level display message to the IPC through the GWM to activate the needle in the fuel gauge.

After a fuel fill up, the time for the fuel gauge to move from empty (E) to full (F) can range from 2 seconds to 55 minutes depending on which operating mode the fuel gauge is in.

The IPC uses 4 different operating modes to calculate the fuel level:

  • Anti-slosh (default mode).
  • Key OFF fueling.
  • Key ON fueling.
  • Recovery.

The default fuel gauge mode is called the anti-slosh mode. To prevent fuel gauge changes from fuel slosh (gauge instability due to changes in fuel sensor readings caused by fuel moving around in the tank), the fuel gauge takes approximately 40 minutes to go from empty (E) to full (F).

The key off fueling mode (2 seconds to read empty [E] to full [F]) requires 3 conditions to be met:

  • The ignition must be in the OFF mode when refueling the vehicle.
  • At least 10% of the vehicle's fuel capacity must be added to the fuel tank.
  • The IPC must receive a valid ignition ON fuel sensor reading within one second of the ignition being put into the RUN mode. The key ON sample readings are considered valid if the fuel sensor reading is between 10 ohms ± 2 ohms and 180 ohms ± 4 ohms.

If these conditions are not met, the fuel gauge stays in the anti-slosh mode, which results in a slow to read full (F) event.

The key ON fueling mode (approximately 60 seconds to read empty [E] to full [F]) requires the following conditions be met:

  • The transmission is in P or N.
  • The ignition is in the RUN mode.
  • At least 10% of the vehicle's fuel capacity must be added to the fuel tank.

In key ON fueling mode, a 30-second timer activates after the transmission is put into the P or N position. When the 30-second time has elapsed and at least 9% of the vehicle's fuel capacity has been added, the fuel gauge response time is 60 seconds to read from empty (E) to full (F). When the transmission is shifted out of P or N, the fuel gauge strategy reverts to the anti-slosh mode. The key ON fueling mode prevents slow to read full events from happening if the customer refuels the vehicle with the ignition in the RUN mode.

Speedometer

The IPC receives the vehicle speed data from the GWM over the HS-CAN3. The GWM receives the vehicle speed message from the PCM over the HS-CAN1.

The PCM uses tire size stored in the vehicle configuration file along with wheel speed inputs to generate a vehicle speed signal. The PCM receives the wheel speed data from the ABS module.

The IPC provides a tolerance that allows the speed indication to display between 3% below and 7% above the actual vehicle speed. This means that with an actual vehicle speed of 97 km/h (60 mph), the speedometer can indicate between 94-103 km/h (58-64 mph). Incorrect tire size or tire size configuration could potentially affect the speedometer accuracy.

Tachometer

The IPC receives the engine rpm data message from the GWM over the HS-CAN3. The GWM receives the engine rpm data message from the PCM over the HS-CAN1.

Temperature Gauge

The IPC uses 2 messages to control the temperature gauge. The first is the engine coolant temperature data, which provides the current coolant temperature input to the PCM. The second message is the engine overheat indication request, which is sent by the PCM to the IPC when an overheating condition exists. When the IPC receives the engine overheat indication request message, the IPC sends the temperature gauge to full hot and turns on the over-temperature warning indicator.

The IPC receives both temperature gauge input messages from the GWM over the HS-CAN3. The GWM receives the engine coolant temperature data and the engine overheat indication request messages from the PCM over the HS-CAN1.

Hybrid Only Gauge

High Voltage Battery Gauge (PHEV, Except China)

The high voltage battery gauge displays the total percentage of battery charge available associated with electric only driving range. A full fill display indicates the total amount of energy obtained from an external charging source (vehicle plugged in). When the fill display indicates empty, the powertrain system will automatically switch to operating in hybrid mode.

The IPC receives the battery state of charge data message from the GWM over the HS-CAN3. The GWM receives the battery state of charge data message from the BECM over the HS-CAN1.

RTT Indicators

ABS Warning

The IPC receives the ABS warning indicator request message from the GWM over the HS-CAN3. The GWM receives the ABS warning indicator request message from the ABS module over the HS-CAN2. If a fault condition exists in the ABS, the ABS module sends the ABS warning indicator request message to either flash or illuminate the ABS RTT warning indicator.

Refer to ABS/Brake/Stability-Traction Control System Indication description for information on the conditions when the ABS warning indicator is turned on.

ABS/Brake/Stability-Traction Control System Indication

The brake/stability-traction control system indication is controlled almost entirely by the ABS module. The ABS module can illuminate multiple indicators for various fault conditions. The following table provides a summary of the basic fault conditions and the indicators that are illuminated for each condition.

NOTE: Refer to the Normal Operation and Fault Condition description before each brake/stability-traction control system indicator Pinpoint Test for the IPC default action for network/missing message conditions.

Component Description

Brake Fluid Level Switch

The brake fluid level switch is mounted in the master cylinder reservoir and is hardwired to the ABS module through a single signal circuit and is grounded through a separate return circuit. The ABS module provides a reference voltage to the brake fluid level switch. When the brake fluid level is low the switch closes, pulling the reference voltage low. When the brake fluid level is high, the switch opens, sending the reference voltage high on the signal circuit to the ABS module.

Engine Oil Pressure Sensor

The engine oil pressure sensor is hardwired to the PCM through VREF, signal and return circuits. The PCM provides the sensor voltage supply on the VREF circuit and monitors the voltage changes through the signal and return circuits as the engine oil pressure changes.

Fuel Level Sender (Float and Card)

The fuel level sender is mounted to the fuel pump and sender unit. The fuel level sender is a dual sweep potentiometer style resistor connected to a float mechanism. Each sweep has multiple fingers that reduces intermittent loss of data. As the fuel level changes, the float rises or falls with the fuel level moving the sweep arm across the resistor wires. This movement either increases or decreases the resistance through the unit. The fuel level sensor resistance ranges from 180 ohms ± 4 ohms to 10 ohms ± 2 ohms. When the fuel level is low, the fuel level sensor resistance is high. When the fuel level is high, the fuel level sensor resistance is low.

The fuel pump and sender unit is hardwired to the IPC through separate signal and return circuits. The fuel level return circuits are grounded internally in the IPC. The IPC provides a reference voltage on the fuel level signal circuit. As the fuel level changes, the change in resistance raises or lowers the fuel level signal voltage depending on the resistance of the fuel level sender. The IPC converts the fuel level signals and sends them to the PCM through the GWM.

IPC

The IPC provides the driver with a system status and alerts the driver when certain conditions exist in the vehicle. The IPC receives the ignition status from the BCM through the GWM over the HS-CAN3.

The IPC requires PMI when it is replaced.

Low Washer Fluid Level Switch

The low washer fluid switch is hardwired to the IPC through a single signal wire and is grounded to a body ground through a separate circuit. The IPC provides a reference voltage to the low washer fluid level switch. When the washer fluid level is low, the float drops closing the switch and pulling the reference voltage low. When the washer fluid level is high, the float lifts opening the circuit to the IPC and sending the reference voltage high.

Seatbelt Buckle Sensor

The seatbelt buckles contain integrated sensors that are Hall-effect switches. The seatbelt buckle sensors are serviced as one component with the seatbelt buckle. The seatbelt buckles are hard-wired inputs to the RCM. The RCM sends the seatbelt buckle status messages to the IPC.

Steering Wheel Switch - Message Center
