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 anti-lock brake system lamp, brake warning lamp, four-wheel drive indicator lamps, headlamp high beam indicator lamp, low washer fluid warning lamp, seat belt reminder lamp driver seat belt switch input, and turn signal indicator lamps are hard-wired. The instrument cluster circuitry uses CCD data bus messages from the Powertrain Control Module (PCM) and Airbag Control Module (ACM) to control all of the remaining indicator lamps.
