Auto door opener malfunction - sense signal

From Service Manual 856487, p.19:

1.Access service mode to confirm the active fault code and read stored error history.

2.Measure door lock assembly resistance across the PTC terminals. Expected: ~200 ohms cold, rising sharply once energized.

3.Inspect strike and latch alignment. A warped door or misaligned strike prevents the switch stack from closing in the correct sequence.
