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.

Circuit/System Verification

Ignition ON, observe the scan tool Driver Information Center Switch parameter, that when the S78 Turn Signal/Multi-Function Switches Menu, Up, Down Set/Clr are pressed and released the scan tool parameter toggles between Menu, Up, Down, Clear and Inactive.

Circuit/System Testing

1. Ignition OFF, disconnect the harness connector at the S78 Turn Signal/Multi-Function Switch.
2. Ignition ON, test for greater than 4.8 V between the harness connector signal circuit terminal 5 and ground.

• If less than the specified range, test the signal circuit for a short to ground. If the circuit tests normal replace the P16 Instrument Cluster.

3. Test for greater than 11 V between the signal S78 Turn Signal/Multi-Function Switch circuit terminal 12 and ground.

• If not within 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.

4. Install a 5 A fused jumper wire between the signal S78 Turn Signal/Multi-Function Switch circuit terminal 12 and the low reference circuit terminal 6. Verify the scan tool Driver Information Center Switch parameter displays 0 V.

• If not the specified value, test the low reference circuit for an open/high resistance. If the circuit tests normal replace the P16 Instrument Cluster.

5. If all circuits tests normal, replace the S78 Turn Signal/Multi-Function Switch.

Repair Instructions
