Instrument Cluster

The instrument cluster controls the courtesy lamps, it receives and sends messages to other modules via the PCI bus circuit, it controls all the instrument illumination and the chime is also an integral part of the cluster. The front turn signals are wired through the cluster and then go to the front lamps. The reason being that the DRL module is built into the cluster (if equipped).

All gauges in the electronic clusters are the analog type gauges. When the ignition switch is moved to the OFF position, the cluster drives each gauge to its lowest position. The individual gauges are not serviceable and require complete replacement of the cluster if one or more gauges are inoperable.

One button is used to switch the display from trip to total mileage. Holding the button when the display is in the trip mode will reset the trip mileage. This button is also used to put the cluster in self-diagnostic mode. Most of the indicators will come on briefly for a bulb check when the ignition switch is turned from OFF to ON. All of the LEDs are replaceable.

The cluster calculates the appropriate odometer mileage based on PCI bus information received from the PCM. The VF display also displays the "Door", "Trac", and "Cruise" messages. If the instrument cluster experiences a loss of communication with the PCI bus, the cluster will display "no buS" in the display. If the cluster determines that there is not 8.0 volts at the battery input, then the cluster shall alternately display "FUSE" and the odometer mileage.

• ABS (if equipped)
  
  PCI bus driven - Cluster will illuminate the ABS indicator after receiving the appropriate message from the ABS module.
• Airbag
  
  PCI bus driven - Cluster will illuminate the air bag indicator after receiving the appropriate message from the airbag control module.
• Battery
  
  PCI bus driven - Cluster will illuminate after receiving the appropriate message from the PCM.
• Brake
  
  Hard wire or PCI bus driven - Cluster will illuminate the park brake indicator if the park brake switch is grounded or after receiving the appropriate message from the ABS module.
• Cruise (if equipped)
  
  PCI bus driven - Cluster will illuminate the cruise indicator after receiving the appropriate message from the PCM.
• Door
  
  Hard wire input - Cluster will illuminate the door indicator if either door input is grounded for more than 250 milliseconds.
• Electronic Throttle Control (ETC) (if equipped)
  
  PCI bus driven - Cluster will illuminate after receiving the appropriate message from the PCM. When the lamp is flashing, with the engine running, there may be power limitations, an elevated/rough idle, and increased brake pedal effort/stopping distances. The light will come on when the ignition switch is first turned ON and remain on briefly as a bulb check. If the light does not come on during the bulb check, if faulty, it is replaceable.
• Front Fog Lamp (if equipped)
  
  Hard wire input - Cluster will illuminate the fog lamp indicator when the front fog lamp input is at Vehicle System Voltage (VSV).
• High Beam
  
  Hard wire input - Cluster will illuminate the high beam indicator whenever the high beam switch input is at Vehicle System Voltage (VSV).
• Left Turn Signal
  
  Hard wire input - Cluster will illuminate the left turn indicator if the left turn signal input is at Vehicle System Voltage (VSV).
• Low Fuel Indicator
  
  Cluster will illuminate the low fuel indicator based upon fuel level calculated by the cluster (using data received from the hard wire input from the fuel level sensor).
• Low Oil Pressure
  
  PCI bus driven - Cluster will illuminate the low oil pressure indicator after receiving the appropriate message from the PCM.
• Multifunction Indicator Lamp (MIL)
  
  PCI bus driven - Cluster will illuminate the indicator after receiving the appropriate message from the PCM.
• Rear Fog Lamp (if equipped)
  
  Hard wire input - Cluster will illuminate the indicator when the rear fog lamp input is at Vehicle System Voltage (VSV).
• Right Turn Signal
  
  Hard wire input - Cluster will illuminate the right turn indicator if the right turn signal input is at Vehicle System Voltage (VSV).
• Seatbelt
  
  Hard wire - Cluster will illuminate the seatbelt indicator whenever the seatbelt input is grounded with the ignition in RUN mode.
• Security (if equipped)
  
  PCI bus driven - Cluster will illuminate the security indicator whenever the remote keyless entry (RKE) input is grounded and the cluster has a battery feed. Cluster will flash the indicator based upon the message received from the sentry key immobilizer module (SKIM).
• Traction Control Active (if equipped)
  
  PCI bus driven - Cluster will illuminate the TRAC indicator after receiving the appropriate message from the ABS module.
• Traction Control Off (if equipped)
  
  PCI bus driven - Cluster will illuminate the TRAC off indicator after receiving the appropriate bus message from the ABS module.

The 7-position dimmer switch input is used by the cluster to determine lighting intensity. The cluster transmits dimming information to other modules via the PCI bus.
