Circuit Description

A new BCM has been installed, ignition switch has been turned to RUN position, but not to START position. When ignition switch is turned to START position, BCM will learn Passlock(tm) code. A relearn will need to be performed to make PCM learn correct fuel enable password. DTC sets when BCM is in learn mode but does not see a valid Passlock(tm) sensor code because of a sensor or wiring problem.
