Instrument Panel Cluster (IPC)
Instrument Panel Cluster (IPC)
NOTE: Select shift Instrument Panel Cluster (IPC) shown, non-select shift IPC (Instrument Panel Cluster) similar.
NOTE: The Smart Junction Box (SJB) is also known as the Generic Electronic Module (GEM).
The Instrument Panel Cluster (IPC) contains gauges, informational indicators, warning indicators and a message center that are designed to provide the driver with system status and to alert the driver that certain conditions exist in the vehicle.
The IPC (Instrument Panel Cluster) uses a 2-line display of basic informational items such as the odometer, trip odometer and for the message center display information.
All indicator lamps and warning indicator lamps are LEDs, which are not replaceable.
Startup (Welcome) Mode
The IPC (Instrument Panel Cluster) provides a startup mode also known as a welcome strategy. When the vehicle receives a Remote Keyless Entry (RKE) request, the IPC (Instrument Panel Cluster) illuminates the gauge pointers and graduation bars. When the key is inserted into the ignition switch, the IPC (Instrument Panel Cluster) illuminates only the graduation bars. When the ignition is placed into the RUN or START position, the IPC (Instrument Panel Cluster) begins a prove-out stage. During the prove-out stage, the IPC (Instrument Panel Cluster) sweeps then zeros all gauges while illuminating all LED indicators for a predetermined time.
MyKey(TM)
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 a MyKey(TM) is in use, the IC (Instrument Cluster) provides the following functions:
- At 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 IC (Instrument Cluster) continuously provides a periodical Belt-Minder(R) warning chime until the driver and passenger safety belts are buckled. When the Belt-Minder(R) is issued, the ACM (Audio Control Module) is muted and the message center displays BUCKLE UP TO UNMUTE RADIO.
- If the MyKey(TM) speed limiter feature is turned on and the vehicle speed approaches 130 km/h (80 mph), the message center displays VEHICLE SPEED 80 MPH MAX along with a chime.
- 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 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(TM) SETTING.
- At 120 km (75 miles) to empty, the IC (Instrument Cluster) illuminates the low fuel indicator (if equipped) and the message center displays 75 MILES TO EMPTY along with a chime
- MyKey(TM) mileages driven by the MyKey(TM) user can be found in the INFO display and in the system check function of the message center.
- The number of MyKey(TM) programmed and admin keys can be found in the system check function of the message center.
- The parking aid, Blind Spot Information System (BLIS(TM)) with Cross Traffic Alert (CTA) (if equipped) and collision avoidance (if equipped) warning menus are disabled in the message center to force these features always on.
When an admin key is in use, the IC (Instrument Cluster) 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) mileages driven by the MyKey(TM) user can be found in system check function of the message center.
- The number of MyKey(TM) and admin keys can be found in the system check function of the message center.
Refer to Antitheft and Alarm Systems for additional information on the MyKey(TM) features.
Gauges
Gauges provide information to the driver indicating the status of systems. The systems that use gauges are as follows:
- Engine temperature
- Engine rpm
- Fuel level
- Vehicle speed
Informational Indicators
Informational indicators provide information to the driver of conditions that exist in the vehicle. The informational indicators are grouped into the following systems/subsystems:
- Engine/powertrain control
- Malfunction Indicator Lamp (MIL)
- Transaxle (grade assist)
- Lighting
- High beam
- Turn signal
- Vehicle control
- Anti-theft
- Cruise control
- Adaptive cruise control
- Traction control
Warning Indicators
Warning indicators provide information to the driver of conditions that could potentially cause personal injury or alter vehicle performance. The warning indicators are grouped into the following systems/subsystems:
- Occupant/driver safety
- Safety belt
- Tire Pressure Monitoring System (TPMS)
- Supplemental Restraint System (SRS) (air bag)
- Vehicle control
- ABS
- Brake system
Message Center Warning Indicators
Message center warning indicators illuminate in the message center and replace the typical informational indicators and warning indicators using the same iconic representation. When multiple warnings exist, the message center warning indicators rotate through each display until each condition has been corrected. The systems that use message center warning indicators include:
Engine/powertrain control
- Charging system
- Engine Temperature
- Low oil pressure
- Powertrain malfunction (wrench)
Occupant/driver safely
- Door ajar
Driver information
- Low fuel
- Low washer fluid
- Trunk ajar
Hardwired Inputs
The hardwired inputs are provided from the following systems or components:
- Compass
- Engine oil pressure switch
- Fuel level
- Message center switch
- Passive Anti-Theft System (PATS)
- Park detect switch
- Traction control disable switch
- Washer fluid
Network Messaged Inputs
Module messaging has increased over time and is becoming the standard for sending and receiving information required to operate the IPC (Instrument Panel Cluster). For a complete list of module messages with the message origination sources, refer to Information Bus.
The status and information messages that the IPC (Instrument Panel Cluster) requires from other vehicle inputs are grouped into the following systems/subsystems:
- ABS
- Anti-lock braking
- Traction control
- Base brake system
