Analog Instrument Panels: Description

WARNING: Deactivate air bag system before performing any service operation. See appropriate AIR BAG RESTRAINT SYSTEMS article. DO NOT apply electrical power to any component on steering column without first deactivating air bag system. Air bag may deploy.

Instrument Panel Cluster (IPC) uses analog speedometer and gauges. Tachometer is standard equipment on Bravada. Tachometer is optional on all other models. See Fig 1 or Fig 2 . IPC contains a microprocessor. Communication with other modules is transmitted over Class 2 serial data bus. Instrument cluster gauges and indicators are provided input from microprocessor or directly from sending units or sensors.

Driver Information Center (DIC) consists of a multi-function electronic display placed in the overhead console. The DIC displays the following information:

Vehicle fuel information.
Outside temperature.
Current vehicle direction.

Display is cycled, changed and acknowledged using US/MET and MODE buttons, located on DIC.

The audible warnings alert the driver of a system concern or a critical vehicle condition. The Body Control Module (BCM) generates the audible warnings through an internal speaker. The BCM emits audible warnings based on various inputs. If the BCM receives multiple audible warning requests, the warning with the highest priority sounds first.
