Instrument Panel Cluster (IPC)

Instrument Panel Cluster (IPC)









Instrument Panel Cluster (IPC)

The Instrument Panel Cluster (IPC) is available either with or without a message center. The IPC contains gauges, informational indicators, warning indicators and message center indicators (message center IPC only) 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 a 2-line display of basic informational items such as the odometer and trip odometer and the message center display information.

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

Gauges

Gauges provide information to the driver indicating the status of systems. The systems that use gauges are as follows:

- Charging system
- Engine coolant temperature
- Engine oil pressure
- 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
- Check fuel cap
- Malfunction Indicator Lamp (MIL)
- Powertrain malfunction (wrench)
- Transmission (Overdrive (O/D)/tow haul)

- Fuel system
- Low fuel

- Lighting
- High beam
- Turn signal

- Vehicle control
- Anti-theft
- Cruise control
- Stability/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:

- Engine/powertrain control
- Charging system
- Engine over-temperature
- Low engine oil pressure

- Occupant/driver safety
- Safety belt
- Supplemental Restraint System (SRS)
- Tire Pressure Monitoring System (TPMS)

- Vehicle control
- ABS
- Brake system

- Vehicle control
- Stability/traction control

Message Center Indicators

Message center indicators illuminate in the message center and replace typical indicators or warning lamps using the same iconic representation that have traditionally been viewed as indicators or warning indicators in the IPC. When conditions exist requiring the use of multiple indicators, the message center indicators rotate through each display until the condition has been corrected. The message center indicators are grouped into the following systems/subsystems:

- Engine/powertrain control
- Charging system
- Check fuel cap
- Engine over-temperature
- Low engine oil pressure
- Powertrain malfunction (wrench)

- Fuel system
- Low fuel

Hardwired Inputs

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

- Compass
- Engine oil pressure switch
- Fuel level
- Park detect
- Passive Anti-Theft System (PATS)

Messaged Inputs

Module messaging is becoming 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.

The status and information inputs that the IPC requires from other vehicle modules are grouped into the following systems/subsystems:

- ABS
- Anti-lock braking
- Electronic Brake Distribution (EBD)
- Stability/traction control

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

- Lighting system
- LH/RH turn
- High beam

- Powertrain
- Charging system
- Engine emission system
- Engine rpm
- Engine temperature
- O/D/tow haul status
- Transmission range
- Vehicle speed

- Occupant/driver safety
- SRS
- TPMS
