DTC B3031: Key Decoder Device On Assembly Learn Mode: Description

Theft deterrent control module checks memory to see if learn coded key setting is on. If learn coded key setting is on, theft deterrent control module stores DTC. When DTC is stored, theft deterrent control module will learn code and SECURITY indicator will be illuminated. DTC will clear when theft deterrent control module does not see learn coded key setting as on. DTC will still be retrieved as current until ignition switch is cycled. DTC will become history at that time.
