Instrument Cluster

INSTRUMENT CLUSTER (IC)







Instrument Cluster
The instrument cluster is available with either a integrated circuit display (base cluster) or with a message center. Both the base cluster and the message center cluster contain gauges, indicator lamps, and warning lamps that are designed to provide the driver with a system status and to alert the driver that certain conditions exist in the vehicle. The instrument cluster lens/mask assembly is the only part that may be installed separately.

Integrated Display
The integrated display contains the odometer, the trip odometer A/B and provides the dealer test mode displays when activated. The SELECT/RESET button has 3 functions. First, pressing the SELECT/RESET button toggles between the odometer and trip odometer settings. When the trip odometer is displayed, pressing and holding the SELECT/RESET button resets the trip odometer. There are 2 trip odometers available. Pressing the SELECT/RESET button while in trip odometer toggles between trip odometer A and trip odometer B. Lastly, the instrument cluster dealer test mode is entered by pressing and holding the SELECT/RESET button down with the ignition switch in the OFF position, then turning the ignition switch to RUN.

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
- Evaporative emissions
- Malfunction indicator lamp (MIL)
- Powertrain malfunction (wrench)

- Lighting
- High beam
- Turn signal

- System status
- Fuel level

- Vehicle control
- Anti-theft
- Speed control
- Traction assist

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 oil pressure

- Occupant/driver safety
- Safety belt
- Door ajar
- Tire pressure monitoring system (TPMS)
- Supplemental restraints system (SRS) (air bag)

- Vehicle control
- ABS
- Brake system

Hardwired Inputs
The hardwired inputs used for the instrument cluster indication are provided from the following systems or components:
- Brake fluid level switch
- Engine oil pressure switch
- Fuel pump module
- Message center switch
- Parking brake switch
- Passive anti-theft system (PATS) transceiver
- Secondary fuel sensor
- Traction control disable switch

Network Messaged Inputs
Module messaging has become the standard for sending and receiving information required to operate the instrument cluster.

The status and information messages that the instrument cluster requires from other vehicle inputs are grouped into the following systems/subsystems:
- Vehicle control
- ABS
- Traction control

- Braking
- Brake fluid
- Parking brake

- Engine/powertrain control
- Charging
- Engine emission system
- Engine rpm
- Engine coolant temperature
- O/D off
- Speed control
- Vehicle speed

- Occupant/driver safety
- Safety belt
- SRS
- TPMS
- Door ajar

- Exterior lighting
- High beam
- LH/RH turn signal
