- Ignition switch status
- Door switch signal (ALL)
- Door lock/unlock signal (Remote keyless entry receiver, each request switch, door lock/unlock switch)
- Trunk room lamp switch signal
- Key switch signal (Key slot)
 BCM provides the interior room lamp power supply continuously when the ignition switch position is other
than OFF.
