Electro-Mechanical Instrument Cluster (EMIC)

The instrument cluster electronically drives the speedometer, odometer, fuel/temperature gauges, and tachometer. On the back of the cluster are two self-docking connectors, a 26-way and a 10-way.

All the indicators are located within the three gauges:

• Speedometer
• Tachometer
• Fuel/Temperature Gauge

This is a smart cluster and used to control many Body Control Module (BCM) functions.

The instrument cluster is referred to as a Electro-Mechanical Instrument Cluster (EMIC). Some of the features it controls are the gauges (except fuel), courtesy lamps, chime control, Daytime Running Lamps (DRL) and cluster self-diagnostics. The cluster sends and receives messages via the Programmable Communication Interface (PCI) data bus circuit. All instrument cluster indicators (Airbag, Seatbelt, etc.) are LED's and are not replaceable, with the exception of the high beam indicator which is a bulb. The gauges are not serviced individually, thereby requiring complete replacement of the cluster if one indicator or gauge becomes defective.

The purpose of the instrument cluster gauges and indicator lamps is to keep the driver informed about the operating condition of the vehicle. If an abnormal condition occurs, the driver is informed by indicator lamp and a chime. The driver can seek service before damage occurs.

The instrument cluster has warning lamps and indicators for the following systems:

• Airbag
• Anti-lock Brakes (ABS) if equipped
• Brake Warning
• Charging System
• Engine Temperature
• Front Fog Lamps (if equipped)
• High Beam
• Liftgate Ajar
• Low Fuel
• Low Oil Pressure
• Malfunction Indicator Lamp (MIL) (Service Engine Soon)
• Seat Belt Warning
• Security System
• Trac-Off (ABS equipped vehicles only)

The instrument cluster has a Vacuum Fluorescent (VF) display for the following systems:

• Cruise
• Door (ajar)
• Odometer
• Trac (ABS equipped vehicles only)
• Trip
