Circuit/System Description
The driver information switches are normally open momentary switches. Power is provided to the driver information center (DIC) switches via the
instrument panel cluster (IPC). The IPC interfaces with the DIC switches via 3 discreet circuits. The switch input to the cluster is pulled low or
grounded when a switch is activated. The IPC reads the voltage at the analog input to determine which switches is pressed. The switch input to the
cluster is set up in a resistor ladder format for three of the four switches. The DIC switches include the PERSONALIZATION, SET/RESET,
TRIP/FUEL, AND VEHICLE INFO switches. A stuck switch or a short to battery sets a DTC.
Conditions for Running the DTC
The ignition is in ACCESSORY or RUN.
Conditions for Setting the DTC
B3567 59
The IPC detects that the DIC switch is stuck.
B3567 01
The IPC detects that the DIC switch signal circuit is shorted to battery.
Action Taken When the DTC Sets
The IPC ignores the DIC switch inputs.
Conditions for Clearing the DTC
* The DTC becomes history when the conditions for setting the DTC are no longer present.
* The history DTC clears after 40 malfunction-free warm-up cycles.
Diagnostic Aids
* When the DIC switches are stuck, only the TRIP/FUEL switch functions correctly. When the TRIP/FUEL switch is stuck, all other DIC
switches function correctly.
* Only the DIC signal circuit can be diagnosed as shorted to battery.
