The driver information switches are normally open momentary switches. Power is provided to the driver information center (DIC) switches via the instrument panel cluster (IPC) ignition 1 voltage circuit. The IPC interfaces with the DIC switches via 4 discreet circuits. Each switch input to the cluster is pulled low or grounded when a switch is activated. The DIC switches include the SET/RESET, MENU, INFO UP, and INFO DOWN switches.

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

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

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

3. Ignition ON, verify all of the scan tool DIC Switch parameters are Inactive.

⇒	If any are not Inactive, test the switch signal circuits listed below for a short to ground. If the circuit test normal, replace the IPC

•	Set/Reset Switch Signal Terminal 2

•	Menu Switch Signal Terminal 5

•	Info. Up Switch Signal Terminal 7

•	Info. Down Switch Signal Terminal 6

4. Ignition ON, install a 3-amp fused jumper wire between the signal circuits listed below and ground. Verify that all of the scan tool DIC Switch parameters are Active.

•	Set/Reset Switch Signal Terminal 2

•	Menu Switch Signal Terminal 5

•	Info. Up Switch Signal Terminal 7

•	Info. Down Switch Signal Terminal 6

⇒	If any are not Active, test the switch signal circuit for a short to voltage or an open/high resistance. If the circuits test normal, replace the IPC.

5. If all the circuits test normal, test or replace the DIC switch assembly.
