Circuit/System Description
The driver information center switch is a multiplexed switch. The Menu button is its own switch. It utilizes a 5 V signal and is normally open. When the Menu button is pressed the signal is pulled low. The Up, Down, Set/Clr buttons are a series of momentary contact switches that connect a series of resistors in a resistor ladder format. The Up, Down, Set/Clr buttons utilize 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 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, observe the scan tool Driver Information Center Switch parameter, that when the S78 turn signal/multifunction switch Menu is pressed and released the scan tool parameter toggles between Menu and Inactive.
2. Ignition ON, observe the scan tool Driver Information Center Switch parameter, that when the S78 turn signal/multifunction switch UP, DOWN, SET/CLR are pressed and released the scan tool parameter toggles between Up, Down, Clear and Inactive.
Circuit/System Testing
1. Ignition OFF, disconnect the harness connector at the S78 turn signal/multifunction switch.
2. Test for less than 30 ohms between the low reference circuit terminal 6 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.
3. Ignition ON, test for 4.8-5.2 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 or an open/high resistance. If the circuit tests normal replace the P16 instrument cluster.
• 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.
4. Test for greater than 10 V between the signal S78 turn signal/multifunction 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.
5. If all circuits tests normal, replace the S78 turn signal/multifunction switch.
Component Testing
1. Ignition OFF, disconnect the harness connectors at the S78 turn signal/multifunction switch.
2. Test for 8.8-9.0k ohms between the signal terminal 12 and the low reference circuit terminal 6.
• If not within the specified range, replace the S78 turn signal/multifunction switch.
3. Test for 550-650 ohms between the signal terminal 12 and the low reference circuit terminal 6 while pressing the Up switch.
• If not within the specified value, replace the S78 turn signal/multifunction switch.
4. Test for 1.5-1.7k ohms between the signal terminal 12 and the low reference circuit terminal 6 while pressing the Down switch.
• If not within the specified value, replace the S78 turn signal/multifunction switch.
5. Test for 3.3-3.7k ohms between the signal terminal 12 and the low reference circuit terminal 6 while pressing the Set/Clr switch.
• If not within the specified value, replace the S78 turn signal/multifunction switch.
6. Test for less than 30 ohms between the signal terminal 5 and the ground circuit terminal 3 while pressing the Menu switch.
• If greater than the specified value, replace the S78 turn signal/multifunction switch.
