Diagnostic Fault Information






Circuit/System Description

The driver information center (DIC) switch is a multiplexed switch. Battery power is provided to the DIC switch via the instrument panel cluster (IPC). The DIC switch signal circuit is pulled up to battery voltage in the IPC. The IPC also provides the DIC switch with a low reference. The switch input to the IPC is pulled 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. The IPC monitors the DIC switch signal circuit to determine the DIC switch inputs. Each switch state - Set/Reset, Trip/Fuel, Vehicle Information, Personalization, INFO UP, INFO DOWN - corresponds to a certain resistance value. The IPC determines the switch pressed by the voltage drop across the resistors.


Conditions for Running the DTC

The ignition is in ACCESSORY or RUN.


Conditions for Setting the DTC

* The IPC detects that the DIC switch is stuck.
* The IPC detects that the DIC switch signal circuit is shorted to battery.



Action Taken When the DTC Sets

The IPC ignores the DIC switch inputs.


Conditions for Clearing the DTC

* The DTC becomes history when the conditions for setting the DTC are no longer present.
* The history DTC clears after 40 malfunction-free warm-up cycles.
* The IPC receives a clear code command from the scan tool.



Diagnostic Aids

* When the Trip/Fuel switch is stuck, all other DIC switches will function correctly. When any of the DIC switches are stuck, only the Trip/Fuel switch functions correctly.
* Only the DIC switch signal circuit can be diagnosed as shorted to battery.

Circuit/System Verification

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

If the parameters do not toggle between Active and Inactive, refer to DIC Switch Malfunction.



Circuit/System Testing

1. Ignition OFF, disconnect the harness connector at the driver information center (DIC) switch.
2. Ignition OFF, test for less than 1 ohm between the low reference circuit terminal 2 and ground.

• If greater than the specified range, test the low reference circuit for an open/high resistance.

3. Ignition OFF, test for less than 1 ohm between the ground circuit terminal 6 and ground.

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

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

• If any are not Inactive, test the signal circuits terminal 1 or terminal 3 for a short to ground. If the circuit tests normal, replace the IPC.

5. Ignition ON, install a 3-amp fused jumper wire between the signal circuit terminal 1 and the low reference circuit terminal 2. Verify the scan tool DIC Switch parameters, except the DIC Fuel Info. parameter are Active.

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

6. Ignition ON, install a 3-amp fused jumper wire between the signal circuit terminal 3 and ground. Verify the scan tool DIC Fuel Info. parameter is Active.

• If not Active, test the signal circuit for a short to voltage or and open/high resistance. If the circuit tests normal, replace the IPC.

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