Important: Always perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure.

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 PERSONALIZATION, SELECT, FUEL, and TRIP switches.

Scan Tool Data List

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 and ground.

⇒	If greater than 1 ohm, test the ground circuit for an open/high resistance.

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

⇒	If any are not Off, test the signal circuit for a short to ground. If the circuit tests normal, replace the IPC

4. Ignition ON, install a 3-amp fused jumper wire between the signal circuit and ground. Verify all of the scan tool DIC Switch parameters are On.

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

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

Important: Always perform the Diagnostic Repair Verification after completing the diagnostic procedure.
