Low Fuel Lamp/Indicator Operation

Note: For additional Description and Operation for the instrument panel refer to Electro/Mechanical Instrument Cluster (EMIC) under the component Instrument Panel. Description and Operation

INSTRUMENT CLUSTER
A single instrument cluster is offered on this model. The cluster is an electromechanical unit that utilizes integrated circuitry and information carried on the Chrysler Collision Detection (CCD) data bus network for control of all gauges and many of the indicator lamps. Some variations of this cluster exist due to optional equipment and regulatory requirements.

The instrument cluster for this model is serviced only as a complete unit. If a cluster gauge or the cluster circuit board are faulty, the entire cluster must be replaced. The cluster lens and hood, the rear cluster housing cover, and the incandescent lamp bulbs and holders are available for service replacement.

Indicator Lamp
Indicator lamps are located in the instrument cluster and are served by the cluster circuit board and connectors. Many of the indicator lamps in the instrument cluster are controlled by the instrument cluster circuitry in response to messages received over the Chrysler Collision Detection (CCD) data bus network.

The headlamp high beam indicator lamp, low washer fluid warning lamp, security lamp and turn signal indicator lamps are hard wired. The seat belt reminder lamp is controlled by the instrument cluster programming and by CCD data bus messages from the Airbag Control Module (ACM). The brake warning lamp is controlled by a hard wired input from the park brake switch and by CCD data bus messages from the Controller Anti-lock Brake (CAB).
The instrument cluster circuitry uses CCD data bus messages from the Powertrain Control Module (PCM), ACM, and CAB to control all of the remaining indicator lamps.

Each of the red indicator lamps in the instrument cluster is illuminated by a dedicated Light-Emitting Diode (LED). If an LED should fail, the entire instrument cluster must be replaced. The remaining indicator lamps in the instrument cluster use incandescent bulbs and holders. Each incandescent indicator lamp has a replaceable bulb and bulb holder.
