Instrument Cluster (IC)

Instrument Cluster (IC)









The Instrument Cluster (IC) contains gauges, informational indicators and warning indicators that are designed to provide the driver with the system status and to alert the driver that certain conditions exist in the vehicle.

The IC uses a 3-line display of basic informational items such as the odometer, trip odometer and clock (for vehicles not equipped with an Audio Control Module (ACM).

All indicator lamps are LEDs, which are not replaceable.

Shipping Mode

The vehicle is placed in a shipping mode at the completion of production to reduce the drain on the battery. Various systems, such as the ACM, Passive Anti-Theft System (PATS), Remote Keyless Entry (RKE) and central locking are altered in how they operate or are disabled when in the shipping mode. Before being transported to the dealer network, the shipping mode is turned off. In the event that the shipping mode is still enabled, the integrated circuit display indicates SHON.

To disable or turn off the shipping mode, carry out the following:

1. Verify the battery is fully charged.

2. With the ignition in the OFF position, press and hold the RESET button on the IC.

3. While holding the RESET button, cycle the ignition to the RUN position, then OFF twice ending in the RUN position within 3 seconds.

4. Continue to hold the RESET button until SHOF or SHIP OFF is displayed.

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

- Lighting
- High beam
- Turn signal
- Rear fog lamps
- Lights on

- Vehicle control
- Anti-theft
- 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:

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

- Occupant/driver safety
- Door ajar
- Low fuel
- 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:

- A/C switch
- Brake fluid level
- Engine oil pressure switch
- Flash to pass
- Fuel level
- High beams
- Network communications High Speed Controller Area Network (HS-CAN) and Medium Speed Controller Area Network (MS-CAN)
- Passive Anti-Theft System (PATS)
- Exterior lighting
- Illumination
- Key-in-ignition
- Parking brake
- Passive Anti-Theft System (PATS)
- Recirculation switch
- Transmission park status

Network 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.

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

- A/C
- ABS
- Traction control

- Lighting system
- LH/RH turn
- Rear log lamps

- Powertrain
- Charging system
- Cruise control
- Electronic Throttle Control (ETC) (wrench)
- Engine rpm
- Engine coolant temperature
- MIL
- Overdrive (O/D) off
- Vehicle speed

- SRS
- Air bag
- Safety belt

- TPMS
- Security/safety
- PATS
- Door ajar
