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 Trip/Fuel switch is stuck, all other DIC switches will function correctly. When any of the DIC switches are stuck, only the
Trip/Fuel switch functions correctly.
* Only the DIC switch signal circuit can be diagnosed as shorted to battery.

Circuit/System Verification
Ignition ON, verify that when the DIC switches are pressed and released the DIC scan tool parameters toggle between Active and Inactive.
Circuit/System Testing
1. Ignition OFF, disconnect the harness connector at the driver information center (DIC) switch.
2. Ignition OFF, test for less than 1 ohm between the low reference circuit terminal 2 and ground.
瀚慖f greater than the specified range, test the low reference circuit for an open/high resistance.
3. Ignition OFF, test for less than 5 ohm between the ground circuit terminal 6 and ground.
瀚慖f greater than the specified range, test the ground circuit for an open/high resistance.
4. Ignition ON, verify that all of the scan tool DIC Switch parameters are Inactive.
瀚慖f any are not Inactive, test the signal circuits terminal 1 or terminal 3 for a short to ground. If the circuit tests normal, replace the IPC.
5. Ignition ON, install a 3A fused jumper wire between the signal circuit terminal 1 and the low reference circuit terminal 2. Verify the scan tool
