4 once out, the slide seal inflates
This sequence is reversed when closing
So, if your error light begins at the beginning of this process , it is an air issue, possibly not enough air pressure in the system to begin the sequence.
If you get an error light later in the sequence, it might indicate too much current draw on the motor which indicates the motor is working too hard.
