Wake-Up/Asleep States

Wake-Ups are signals that turn the BCM On and cause it to begin active control and/or monitoring. The High Power Mode activates for a time period of 15 minutes when the BCM is awakened. The components are restored with Controlled Power during this time period. After 15 minutes the BCM transitions to the Low Power and the No Controlled Power Mode.

The following are the wake-up signals:
^ Any ignition state transition.
^ Any of the following with the ignition in the Lock position:
- Any door jamb switch becoming active (i.e. a transition from closed to open).
- The trunk being opened (i.e. a transition from closed to open).
^ A Class 2 RFA-Button report being received.

The low power current sense feedback is a BCM wake-up. The BCM wakes-up and enters the High Power Mode when the low power output is active with the BCM asleep and with the current sense feedback over a threshold of 2.4 amps.

The BCM is asleep when it has stopped monitoring and has become idle. The BCM deactivates Low Power and transitions to the No Controlled Power Mode after inactivity of 3 days plus 15 minutes (controlled power shutdown time). The High and the Low Power are deactivated and remain inactive until a wake-up is received when the BCM is in the No Controlled Power Mode. The following occurs before the transition to the No Controlled Power Mode:
^ The BCM issues a bus wake-up and a Controlled Power Shutdown Report on the Class 2 bus indicating that the sequence has begun.
^ The components powered by the Controlled Power perform necessary data storage.
^ The BCM turns off the Low Power first and then the High Power Control output a minute after the Class 2 shutdown report.
