Asleep States

The BCM is Asleep when it has stopped controlling or monitoring devices and has become idle again. After the ignition switch is turned to the lock position and 20 minutes (1216 seconds) elapse without any wake-up signals, the BCM enters into a sleep state and goes into the low power mode. If the BCM is in low power mode and detects a wake-up command, the BCM will enter into the wake-up state and enter the high power mode. If the vehicle has been left inactive (ignition in the lock position and no BCM wake-ups) for 20 minutes, the BCM will return to the low power mode.
