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. Check 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 X2 harness connector at the S78 Turn Signal/Multi-Function Switch.

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

3. 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.

4. If greater than the specified range, test the signal circuit for a short to voltage. If the circuit tests normal replace the P16 Instrument Cluster.

5. Test for B+ between the signal circuit terminal 12 and ground.

6. If less than the specified value, test the signal for a short to ground or an open/high resistance. If the circuit tests normal replace the P16 Instrument Cluster.

7. Install a 5 A fused jumper wire between the signal circuit terminal 12 and the low reference circuit terminal 6. Verify the scan tool Driver Information Center Switch parameter displays 0 V.

8. 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.

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


Component Testing


Static Test

1. Ignition OFF, disconnect the harness connectors at the S78 Turn Signal/Multi-Function Switch.

2. Test for 8.8-9.0k Ω between the signal terminal 12 X2 and the low reference circuit terminal 6 X2.

3. If not within the specified range, replace the S78 Turn Signal/Multi-Function Switch.

4. Test for 550-650 Ω between the signal terminal 12 X2 and the low reference circuit terminal 6 X2 while pressing the Up switch.

5. If not within the specified value, replace the S78 Turn Signal/Multi-Function Switch.

6. Test for 1.5-1.7k Ω between the signal terminal 12 X2 and the low reference circuit terminal 6 X2 while pressing the Down switch.

7. If not within the specified value, replace the S78 Turn Signal/Multi-Function Switch.

8. Test for 3.3-3.7k Ω between the signal terminal 12 X2 and the low reference circuit terminal 6 X2 while pressing the Set/Clr switch.

9. If not within the specified value, replace the S78 Turn Signal/Multi-Function Switch.

10. Test for less than 30 Ω between the signal terminal 5 X2 and the ground circuit terminal 3 X2 while pressing the Menu switch.

11. If greater than the specified value, replace the S78 Turn Signal/Multi-Function Switch.
