Circuit/System Description

When replacing a body control module (BCM), the engine control module (ECM) must learn the new fuel enable password from the replacement BCM. If the ECM is replaced with a service replacement part, it is in a functional state to automatically learn the vehicle fuel continue password. If the BCM is replaced, the ECM must be placed in learn mode so it can learn the new BCM password. This DTC indicates the ECM is in a functional state to learn the BCM fuel enable password.
