Instrument Panel Cluster (IPC)




Instrument Panel Cluster (IPC)

NOTE: Base Instrument Panel Cluster (IPC) equipped with gasoline engine and automatic transmission shown, other IPC configurations similar.









NOTE: Optional message center Instrument Panel Cluster (IPC) equipped with gasoline engine and automatic transmission shown, other IPC configurations similar.









Instrument Panel Cluster (IPC)

The Instrument Panel Cluster (IPC) is available either with a base message center (identified by the 3-button message center switch) or with the optional message center (identified by the 5-button message center switch). The IPC contains gauges, informational indicators, warning indicators and message center indicators that are designed to provide the driver with system status and to alert the driver that certain conditions exist in the vehicle.

The IPC uses part of the message center as a display area for basic informational items such as the odometer and trip odometer and for the message center display information.

All indicator lamps and warning indicator lamps are LEDs, which are not replaceable.

Informational Indicators/Warning Indicators

Informational indicators provide information to the driver of conditions that exist in the vehicle. Warning indicators provide information to the driver of conditions that could potentially cause personal injury or alter vehicle performance.

Instrument Panel Cluster (IPC) Message Center Indicators - Base IPC

Message center indicators illuminate in the message center and replace the typical informational or warning indicator using the same iconic representation. When multiple warnings exist, the message center indicators cycle through each display until the condition has been corrected. The message center indicators include:

- Charging system
- Check fuel cap
- Door ajar
- Electronic locking differential
- Engine oil pressure (diesel only)
- Engine over-temperature
- Low fuel
- Powertrain malfunction (wrench)
- Traction control off (Engine Only Traction Control (EOTC))
- Water in fuel (diesel only)

Instrument Panel Cluster (IPC) Message Center Indicators - Optional IPC

Message center indicators illuminate in the message center and replace the typical informational or warning indicator using the same iconic representation. The message center indicator display area uses 6 separate boxes. The first 3 boxes are fixed displays and the last 3 boxes are rotating displays. When multiple warnings exist, the rotating message center indicators cycle through each display until the condition has been corrected. The message center indicators include:

- 4x2, 4x4 high and 4x4 low (fixed)
- Check fuel cap
- Diesel exhaust fluid level (urea)
- Door ajar
- Electronic locking differential (fixed)
- Engine oil pressure
- Engine over-temperature
- Low fuel
- Powertrain malfunction (wrench)
- Traction control off ( EOTC)
- Water in exhaust fluid (urea) (diesel only)
- Water in fuel (diesel only)

Hardwired Inputs

The hardwired inputs are provided from the following systems or components:

- 4WD
- Fuel level
- Message center switch
- Park detect
- Transmission control switch (hill descent)
- Traction control switch

Messaged Inputs

Module messaging has increased over time and has become the standard for sending and receiving information required to operate the IPC. For a complete list of module messages with the message origination sources, refer to Module Communications Network Testing and Inspection.

Listed below is a partial list of status and information messages that the IPC requires from other vehicle inputs:

- ABS
- ABS braking
- Roll Stability Control (RSC(R))
- Stability/traction control

- Base brake system
- Brake fluid level status
- Parking brake status

- Lighting system
- LH/RH turn
- High beam
- Door ajar

- Powertrain
- Engine emission system
- Engine oil pressure
- Engine rpm
- Engine temperature
- Tow haul status
- Transmission range
- Vehicle speed

- Supplemental Restraint System (SRS)
- Tire Pressure Monitoring System (TPMS)
- Delayed accessory

Startup (Welcome)/Shutdown (Farewell) Mode

The IPC provides a startup/shutdown mode also known as a welcome/farewell strategy. When the vehicle receives a Remote Keyless Entry (RKE) request or a door ajar (open) message, the IPC gradually increases illumination of the gauge trim rings and turns on the message center (the optional IPC provides a welcome graphic). When the key is inserted into the ignition switch (key OFF), the IPC illuminates the gauge points. When the ignition is placed into the RUN or START position, the IPC begins a prove-out stage. During the prove-out stage, the IPC sweeps then zeros all gauges, provides message center information (replaces the welcome screen with vehicle specific information on the optional IPC) while illuminating all LED indicators for a predetermined time. For the shutdown, the IPC reverses the startup process.

MyKey(TM)

NOTE: All MyKey(TM) displayed messages listed below are base IPC (3-button message center switch) displays. The optional IPC (5-button message center switch) message displays are similar.

The MyKey(TM) feature allows the customer to program a restricted driving mode that is tied to one or more keys known as a MyKey(TM). When MyKey(TM) is in use, the IPC provides the following functions:

- At the beginning of vehicle start up, as part of the welcome strategy, the message center greets the MyKey(TM) driver with MYKEY ACTIVE DRIVE SAFELY displayed in the message center. If the MyKey(TM) speed limiter feature is turned on, the message center also displays SPEED LIMITED TO 80 MPH (or 130 km/h).
- The IPC continuously provides a periodic Belt-Minder(R) warning chime until the driver and passenger safety belts are buckled. When the Belt-Minder(R) is issued, the Audio Control Module (ACM) is muted and the message center displays BUCKLE UP TO UNMUTE AUDIO.
- If the MyKey(TM) speed limiter feature is turned on and the vehicle speed approaches 120 km/h (75 mph), the message center displays VEHICLE NEAR TOP SPEED along with a chime.
- If the MyKey(TM) speed limiter feature is turned on and the vehicle speed reaches 130 km/h (80 mph), the message center displays VEHICLE AT TOP SPEED DRIVE SAFELY along with a chime.
- If the speed warning is selected at one of the pre-set values (75, 90, 105 km/h [45, 55, 65 mph]) and the vehicle approaches the pre-set speed, the message center displays CHECK SPEED DRIVE SAFELY along with a chime.
- If the traction control always on feature is turned on and the MyKey(TM) driver presses the traction control switch to disable traction control, the message center displays ADVTRAC ON MYKEY SETTING (base IPC) or ESC ALWAYS ON MYKEY SETTING (optional IPC).
- At 1/8 tank of remaining fuel, the IPC illuminates the low fuel indicator (if equipped) and the message center displays the appropriate Distance To Empty (DTE) message along with a chime.
- MyKey(TM) miles driven by the MyKey(TM) user can be found in the information display and in the system check function of the message center on the base IPC and in the information display only on the optional IPC.
- The number of MyKey(TM) programmed and administrator keys can be found in the system check function of the message center (base IPC) or information function (optional IPC).
- The parking aid warning menu is disabled in the message center to force these features always on.

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

- The message center provides a menu that guides the user to create a MyKey(TM). When the maximum MyKey(TM) limit is reached, the MyKey(TM) creation menu is no longer available.
- The message center provides menus for setting 4 optional MyKey(TM) features:
- MyKey(TM) 80 MPH speed limiter
- MyKey(TM) pre-selected speed warning
- MyKey(TM) radio volume limiter
- AdvanceTrac(R) on/off

- The message center provides a menu to clear all MyKey(TM) programmed keys at once.
- MyKey(TM) miles driven by the MyKey(TM) user can be found in the information display and in the system check function of the message center on the base IPC and in the information display only on the optional IPC.
- The number of MyKey(TM) programmed and administrator keys can be found in the system check function of the message center (base IPC) or information function (optional IPC).

For additional information, refer to Anti-Theft - Passive Anti-Theft System (PATS) Anti-Theft - Passive Anti-Theft System (PATS) on the MyKey(TM) features.
