CIRCUIT DESCRIPTION
The Theft Deterrent (VTD) Module performs an internal test on the non-volatile memory every 300 milliseconds. If the test fails the VTD module will indicate a memory malfunction is current.

ACTION TAKEN WHEN THE DTC SETS
^ Stores a DTC B2734 in the VTD module memory.

^ Use the On-Boards clearing DTCs feature.
^ A history DTC will clear after 50 consecutive ignition cycles if the condition for the malfunction is no longer present.
