1. Driver Information Center Switch Malfunction
|
|
|
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 - 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, while pressing and releasing the S78 Turn
Signal/Multi-Function Switch Menu, UP, DOWN, and SET/CLR buttons.
The reading should toggle 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 OFF for more than 60
s, test for less than 5 Ω 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, verify the scan
tool Driver Information Center Switch parameter is Inactive.
|
⇒ |
If not Inactive, test the signal circuits terminal
5 and terminal 12 for a short to ground. If the circuit tests
normal, replace the P16 Instrument Cluster. |
4. |
Ignition ON, install a 680
Ω resistance between the signal circuit terminal 12 and the
low reference circuit terminal 6. Verify the scan tool Driver
Information Center Switch parameter is Up. |
⇒ |
If not Up, test the signal circuit for a short to
voltage or an open/high resistance. If the circuit tests normal,
replace the P16 Instrument Cluster. |
5. |
Ignition ON, install a 3 A
fused jumper wire between the signal circuit terminal 5 and the low
reference circuit terminal 6. Verify the scan tool Driver
Information Center Switch is Menu. |
⇒ |
If not Menu, test the signal circuit for a short
to voltage or an open/high resistance. If the circuit tests normal,
replace the P16 Instrument Cluster. |
6. |
If all circuits test normal,
test or replace the S78 Turn Signal/Multi-Function Switch.
|
Component Testing
Static Test
1. |
Ignition OFF, disconnect the
harness connector at the S78 Turn Signal/Multi-Function
Switch. |
2. |
Test for 8.5-9.1 kΩ
between the signal terminal 12 and the low reference circuit
terminal 6. |
⇒ |
If not within the specified range, replace the S78
Turn Signal/Multi-Function Switch. |
3. |
Test for 550-650 Ω
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/Multi-Function Switch. |
4. |
Test for 1.5-1.7 kΩ
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/Multi-Function Switch. |
5. |
Test for 3.3-3.7 kΩ
between the signal terminal 12 and the low reference circuit
terminal 6 while pressing the Reset switch. |
⇒ |
If not within the specified value, replace the S78
Turn Signal/Multi-Function Switch. |
6. |
Test for less than 5 Ω
between the signal terminal 5 and the low reference circuit
terminal 6 while pressing the Menu switch. |
⇒ |
If greater than the specified value, replace the
S78 Turn Signal/Multi-Function Switch. |
