B3031

Diagnostic Chart:

SCHEMATIC
Refer to 160/310 Cell 133: Vehicle Theft Deterrent Module schematic

CIRCUIT DESCRIPTION
The vehicle theft deterrent (VTD) module checks memory to see if the Learn Coded Key setting is on. If so, the VTD sets this DTC.

RUNNING THE DTC
The VTD must see the ignition switch input. The VTD can not have a B1327 set as a current DTC.

CONDITIONS FOR SETTING THE DTC
If the Learn Coded Key setting is on, the VTD sets this DTC.

ACTION TAKEN WHEN THE DTC SETS
The VTD will learn the key code. The VTD will illuminate the security indicator.

CONDITIONS FOR CLEARING THE MIL/DTC
The VTD clears the current status of the DTC when it does not see the Learn Coded Key setting as on. The DTC will still be retrieved as current until the ignition switch is cycled. The DTC will become a history DTC at that time.

TEST DESCRIPTION
The numbers below refer to the step numbers on the diagnostic table.
2. To set this code, a key with a working transponder was read by the VTD (Pass Key III(R)) Module. For that key to operate the vehicle a 10 Minute or 30 Minute Re-Learn Procedure must be performed.
