Instrument Cluster (IC)

Instrument Cluster (IC)

NOTE: Gasoline vehicles equipped with automatic transmission shown, other Instrument Cluster (IC) configurations similar.











Instrument Cluster (IC)

The Instrument Cluster (IC) is available either with a full function message center (identified by the 3 button message center switch) or with a base message center (identified by the single stem reset button in the IC). The IC 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 IC uses a 2-line display 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.

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
- Transmission temperature (automatic transmissions only)
- Turbo boost (diesel only)
- Vehicle speed

Informational Indicators

Informational indicators provide information to the driver of conditions that exist in the vehicle. The systems that use informational indicators include:

- Anti-theft
- Four-Wheel Drive (4WD)
- High beam
- Powertrain
- Cruise control
- Turn signal
- Tow haul
- Wait to start (diesel only)

Warning Indicators

Warning indicators provide information to the driver of conditions that could potentially cause personal injury or alter vehicle performance. The systems that use warning indicators include:

- ABS
- Brake system (indicating low brake fluid, parking brake applied or other ABS brake system concerns)
- Charging system
- Engine oil pressure (low) (gasoline only)
- Safety belt buckle status (driver side only)
- Supplemental Restraint System (SRS)
- Tire Pressure Monitoring System (TPMS)

Message Center Indicators

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

- Powertrain malfunction (wrench)
- Check fuel cap
- Door ajar
- Engine oil pressure (diesel only)
- Engine over-temperature (failsafe)
- Low fuel
- Traction control
- Water in fuel (diesel only)

Hardwired Inputs

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

- Compass
- Engine oil pressure switch
- 4WD
- Fuel level
- Message center switch
- Park detect
- Passive Anti-Theft System (PATS)

Messaged Inputs

Module messaging has increased over time and is becoming the standard for sending and receiving information required to operate the IC. For a complete list of module messages with the message origination sources, refer to Information Bus.

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

- ABS
- 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 rpm
- Engine temperature
- Tow haul status
- Transmission range
- Vehicle speed

- SRS
- TPMS
- Delayed accessory
