The Cold Cranking Pulse occurs when starting the engine in the morning and even worse in cold weather. Controllers supporting CAN bus will be notified that a temporary low battery voltage condition will occur. Motion controllers modules (e.g. power lift gate) driving in that moment electrical motors will have to stop the ongoing operation and store their current status (e.g. lift gate position and direction) just before the Cold Cranking Pulse occurs. Once the Battery voltage returns to nominal (e.g. 12.8 V) the motion controller should safely resume its operation.
