LP6. BLOCKING/UNLOCKING DOORS NOT OPERATING
RECOMMENDATION Check with the CLIP tester the absence of the failures.
If there are memorised failures, these must be removed.
Are the doors blocking mechanisms correctly
operating ?Repair the damaged mechanisms.No
Check the continuity a nd the isolation related to the ground
of the wiring between :
E.C.U . d ecoder pin B8 actuators
Pin B9 doors
Is the wiring in good condition?
Fix the wiring.No
Check the continuity a nd the isolation related
to the ground of the wiring between
E.C.U .pin B8 switch
d ecoder pin B9 blocking doors
Is the wiring in good condition?
Repair.
Di sconnect the E.C.U. decoder, then supply
the wiring connector with +12 V at pin B9 and
the ground at the pin B8, than versa (+ 12 V at
pin B8 and the ground at pin B9).
Ar e the actuators bl ocking/unlocking the
doors?
Damaged actuators.
Replace them.
Replace the E.C.U. decoder, then perform the “E.C.U. decoder replacement
procedure”. No
