The driver information center (DIC) displays important vehicle information including compass and ambient air temperature. Power is provided to the DIC via the IP Fuse Block. The DIC communicates with the instrument panel cluster (IPC) via the serial data circuit. The DIC monitors the DIC switch signals to determine the switch inputs. The switch inputs to the DIC are low when a switch is activated. The DIC switch is a momentary contact switch that connects a series of resistors in a resistor ladder format. Each switch state - GAGES, TRIP ODOMETER, SET/RESET, INFO, FUEL, OPTIONS - corresponds to a certain resistance value.

Ignition ON, verify that all scan tool DIC Switch parameters toggle between Active and Inactive when pressed and released the switches.

1. Ignition OFF, disconnect the harness connector at the DIC.
2. Ignition OFF, test for less than 1 ohm between the ground circuit terminal F and ground.

⇒	If greater than the specified value, test the ground circuit for an open/high resistance.

3. Ignition ON, verify that a test lamp illuminates when connected between the battery positive voltage circuit terminal L and ground.

⇒	If the test lamp does not illuminate, test the battery positive voltage circuit for an open/high resistance. If the circuit tests normal, test or replace the DIC.

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
