System Initialization

System initialization is necessary to identify the liftgate closed (0-Position) position.

After a Battery Power-on reset, an initialization process must be executed to find the full open and full closed liftgate position. After successful initialization for liftgate closed position and learning of the liftgate full open position the normal liftgate open and close operation can be ensured. Procedure:

1. After Power-on, the Latch status is checked to identify the liftgate position status.
2. If the Latch is open, it is assumed that liftgate is open and the inner switch illumination is switched on
3. If the Latch is closed, it is assumed that liftgate is closed. Therefore, the liftgate position is set to zero and the initialization is completed.
