Circuit/System Description



The driver information center switch is a multiplexed switch. Battery power is provided to the driver information center switch via the instrument



cluster. The driver information center switch signal circuit is pulled up to battery voltage in the instrument cluster. The instrument cluster also



provides the driver information center switch with a low reference. The switch input to the instrument cluster is pulled low when a switch is



activated. The driver information center switch is a momentary contact switch that connects a series of resistors in a resistor ladder format. The



instrument cluster monitors the driver information center switch signal circuit to determine the driver information center switch inputs. Each switch



state Menu, Up, Down, Clear corresponds to a certain resistance value. The instrument cluster determines the switch pressed by the voltage drop



across the resistors.



Conditions for Running the DTC



* The ignition is in OFF, ACCESSORY or RUN position.



* The system voltage is between 9-16 V.



Conditions for Setting the DTC



B3567 01



The instrument cluster detects that the driver information center switch signal circuit is shorted to battery.



B3567 02



The instrument cluster detects that the driver information center switch signal circuit is shorted to ground.



B3567 04



The instrument cluster detects that the driver information center switch signal circuit is open.



B3567 59



The instrument cluster detects that the driver information center switch is stuck.



Action Taken When the DTC Sets



The instrument cluster ignores the driver information center switch inputs.



Conditions for Clearing the DTC



The DTC will become history if the instrument cluster no longer detects a malfunction.
