DTC B1517: DIC Switch 2 Signal (Short To Ground): Description

Driver Information Center (DIC) contains 6 switch circuits that allow IPC functions to be performed. IPC supplies a 5-volt reference voltage signal to each switch circuit. When any DIC switch is pressed, voltage will be pulled low when circuit is grounded through DIC switch. IPC monitors DIC switch circuits and determines how long any circuit experiences voltage changes.

DTC B1517 will set when IPC detects a low voltage level (short to ground) in DIC switch 2 (GAGES) circuit for 60 seconds. No driver warning message will be displayed.

If conditions for malfunction no longer exist, history DTC will clear after 50 consecutive ignition cycles. DTC B1517 will also clear when conditions no longer exist, or when IPC or scan tool is used to clear codes.

NOTE: If DTC B1517 is a history code, problem may be intermittent. Wiggle wires while performing the following test.

NOTE: If DIC switch 2 (GAGES) is pressed for longer than 60 seconds, DTC B1517 may set with no existing malfunctions. Always verify that this condition does not exist before diagnosing DTC B1517.
