To check the wiring, with the door
open, measure on the following
wiring connectors:
- between wire J5-2 and J5-3,
the circuit must NOT be open
(measure the resistance value of
the PTC).
- between wire J5-1 and J5-2,
the circuit must be OPEN.
Is the system ok?

Check the mechanical coupling
between the door lock and the door
latch. Is the system efficient?
