Driver Information Center (DIC) Switch(es) Inoperative

Diagnostic Instructions

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



Circuit/System Description

The driver information center (DIC) monitors the DIC switch signals to determine the switch inputs. The switch inputs to the DIC is 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.

Circuit/System Testing

Ignition ON, verify that all scan tool DIC Switch parameters toggle between Active and Inactive while pressing and releasing the switches.

If any DIC switch parameters does not toggle between Active and Inactive, replace the DIC.



Repair Instructions

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