Driver Information Center (DIC) Switch Malfunction

Driver Information Center (DIC) Switch Malfunction

Diagnostic Instructions

* Perform the Diagnostic System Check - Vehicle (Diagnostic System Check - Vehicle) prior to using the diagnostic procedure.
* Review Strategy Based Diagnosis (Strategy Based Diagnosis) for an overview of the diagnostic approach.
* Diagnostic Procedure Instructions (Diagnostic Procedure Instructions)provides an overview of each diagnostic category.

Circuit/System Description

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.

Circuit/System Testing

1. Ignition OFF, disconnect the harness connector at the DIC switch assembly.
2. Ignition OFF, test for less than 1 ohm between both ground circuits terminal 4 and ground.

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

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

• If any are not the specified value, test the appropriate 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 all the signal circuits terminals 2 and 3 and ground. Verify all of the scan tool DIC Switch parameters are On.

• If any are not the specified value, test the appropriate 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.

Repair Instructions

Perform the Diagnostic Repair Verification (Verification Tests) after completing the diagnostic procedure.
