Check that all the connectors are correctly inserted
!
Fig. 4
To check the wiring, with the
door open, measure on the
following wiring connectors
(Fig. 4)
:
- 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?
Replace the door
lock and repeat
the diagnostic
cycle to check for
any further
alarms.
Replace the circuit board and
repeat the diagnostic cycle to
check for any further alarms.
Measure the continuity
between connector J5 (main
circuit board) and the door lock
connector
Is the wiring ok?
Replace the
wiring and repeat

cycle to check for
any further
alarms
Replace the circuit board and repeat the diagnostic
cycle to check for any further alarms.
YES
NO
YES
Detach the connectors and
measure on the component
(Fig. 9):
- between connectors 3 and 4,
the circuit must not be open
(measure the resistance value
of the PTC).
- on the other hand, between
connectors 4 and 5, the circuit
must be open (the numbers
are printed on the
component).
Is the door interlock ok?
NO
NO
