Circuit Description
The theft deterrent control module checks memory to see if the Learn Coded Key setting is on. If so, the theft deterrent control module sets this DTC.
Conditions for Running the DTC
The microprocessor runs the program to detect a check sum error after each power up. This program runs only if the DTC B1982 or B1983 are not set as a current DTCs.
Conditions for Setting the DTC
If the Learn Coded Key setting is on, the theft deterrent control module sets this DTC.
Action Taken When the DTC Sets
The theft deterrent control module will learn the key code. The security indicator will be illuminated for this DTC.
Conditions for Clearing the MIL/DTC
The theft deterrent control module 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.
