Diagnostic Fault Information

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

1. Ignition ON.
2. Verify the driver information center set, up and down function changes when pressing the set, up or down switch.

• If the driver information center does not change

Refer to Set, Up and Down Switch Malfunction

• If the driver information center changes

3. Verify the driver information center menu function changes when pressing the menu switch.

• If the driver information center does not change

Refer to Menu Switch Malfunction

• If the driver information center changes

4. All OK.

Circuit/System Testing

Menu Switch Malfunction

1. Ignition ON.
2. Test for 4.8-5.2 V between the signal circuit terminal 5 and ground.

If less than 4.8 V

1. Ignition OFF, disconnect the harness connector at the P16 Instrument Cluster.
2. Test for infinite resistance between the signal circuit and ground.

• If less than infinite resistance, repair the short to ground on the circuit.
• If infinite resistance

3. Test for less than 2 ohms in the signal circuit end to end.

• If 2 ohms or greater, repair the open/high resistance in the circuit.
• If less than 2 ohms, replace the P16 Instrument Cluster.
• If greater than 5.2 V

1. Ignition OFF, disconnect the harness connector at the P16 Instrument Cluster, ignition ON.
2. Test for less than 1 V between the signal circuit and ground

• If 1 V or greater, repair the short to voltage on the circuit.
• If less than 1 V, replace the P16 Instrument Cluster.
• If between 4.8-5.2 V

3. Test for less than 10 ohms between the ground circuit terminal 3 and ground.

• If 10 ohms or greater

Repair the open/high resistance in the circuit

• If less than 10 ohms

4. Test or replace the S78 Turn Signal/Multifunction Switch.

Set, Up and Down Switch Malfunction

1. Ignition OFF and all vehicle systems OFF, disconnect the X1 harness connector at the S78 Turn Signal/Multifunction Switch, ignition ON.
2. Test for less than 10 ohms between the low reference circuit terminal 6 and ground.

• If 10 ohms or greater

1. Ignition OFF, disconnect the harness connector at the P16 Instrument Cluster.
2. Test for less than 2 ohms in the low reference circuit end to end.

• If 2 ohms or greater, repair the open/high resistance in the circuit.
• If less than 2 ohms, replace the P16 Instrument Cluster.
• If less than 10 ohms

3. Test for 9.8-12.2 V between the signal circuit terminal 12 and ground.

If less than 9.8 V

1. Ignition OFF, disconnect the harness connector at the P16 Instrument Cluster.
2. Test for infinite resistance between the signal circuit and ground.

• If less than infinite resistance, repair the short to ground on the circuit.
• If infinite resistance

3. Test for less than 2 ohms in the signal circuit end to end.

• If 2 ohms or greater, repair the open/high resistance in the circuit.
• If less than 2 ohms, replace the P16 Instrument Cluster.
• If greater than 12.2 V

1. Ignition OFF, disconnect the harness connector at the P16 Instrument Cluster, ignition ON.
2. Test for less than 1 V between the signal circuit and ground.

• If 1 V or greater, repair the short to voltage on the circuit.
• If less than 1 V, replace the P16 Instrument Cluster.
• If between 9.8-12.2 V

4. Test or replace the S78 Turn Signal/Multifunction Switch.
