Circuit/System Description

The driver information centre switch is a multiplexed switch. The Select, Back, and Config buttons are a series of momentary contact switches that connect a series of resistors in a resistor ladder format. The Select, Back, and Config buttons utilise a 12 V signal and the instrument cluster determines which button is pressed by the voltage drop across the resistors when the button is pressed.

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 centre switch signal circuit is shorted to battery.

B3567 02

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

B3567 04

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

B3567 59

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

Action Taken When the DTC Sets

The instrument cluster ignores the driver information centre switch inputs.

Conditions for Clearing the DTC

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

Circuit/System Verification

Vehicle in Service Mode, observe the scan tool Driver Information Centre Switch parameter, that when the S16 driver information centre switch, Select, Back, and Config are pressed and released the scan tool parameter toggles between Select, Back, and Config and Inactive.

Circuit/System Testing

Vehicle OFF, disconnect the harness connector at the S16 driver information centre switch.
Test for less than 10 Ω 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. If the circuit tests normal replace the P16 instrument cluster.

Vehicle in Service Mode, test for 10-12 V between the signal S16 driver information centre switch signal circuit terminal 1 and ground.

⇒	If less than the specified range, test the signal for an open/high resistance or a short to ground. If the circuit tests normal replace the P16 instrument cluster.

⇒	If greater than the specified range, test the signal circuit for a short to high voltage. If the circuit tests normal, replace the P16 instrument cluster.

If all circuits tests normal, test or replace the S16 driver information centre switch.
