Instrument Panel Cluster (IPC)

Instrument Panel Cluster (IPC)









NOTE: The Smart Junction Box (SJB) is also known as the Generic Electronic Module (GEM).

The Instrument Panel Cluster (IPC) has a full function message center (identified by the 3-button message center switch). The IPC contains gauges, informational indicators and warning 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 a message center display area for basic informational items such as the odometer and trip odometer and for the text-based message center display information.

Gauges

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

- Engine coolant 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)
- Powertrain malfunction (wrench)
- Transmission (overdrive)

- Lighting
- High beam
- Turn signal

- Vehicle control
- Anti-theft
- Adaptive cruise control
- Speed 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:

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

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

- Vehicle control
- ABS
- Brake system

Hardwired Inputs

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

- Engine oil pressure switch
- Fuel level
- Message center switch
- Passive Anti-Theft System (PATS) transceiver
- Traction control disable switch

Network 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 Information Bus.

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

- ABS
- Anti-lock braking
- Traction control

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

- Lighting system
- LH/RH turn
- High beam

- Powertrain
- Charging
- Engine emission system
- Engine rpm
- Engine temperature
- O/D off
- Vehicle speed

- SRS
- TPMS
- Intelligent Access (IA)
