Schematics:

CIRCUIT DESCRIPTION
The instrument panel cluster (IPC) contains switch circuits that allow certain functions to be performed when depressed. The IPC monitors these circuit voltage levels and detects when a certain button has been depressed by the voltage drop. If the voltage is not within range for a per determined amount of time, the IPC detects the malfunction and sets a DTC.

CONDITIONS FOR RUNNING THE DTC
The IPC and the fuel info switch must be active.

CONDITIONS FOR SETTING THE DTC
The IPC detects the fuel info switch stuck closed or grounded for more than 15 continuous seconds.

ACTION TAKEN WHEN THE DTC SETS
The IPC will disable (ignore) the mode switch input.

CONDITIONS FOR CLEARING THE DTC
The IPC does not detect a failure for two passes through the diagnostic self test.

DIAGNOSTIC AIDS
The IPC will store the code as current only as long as the failure exists. An intermittent failure will be stored as a history DTC.

TEST DESCRIPTION
The numbers below refer to the step numbers on the diagnostic table.
4. Tests for a short to ground in the signal circuit.
