QUICKLY (the engine doesn’t start)

RECOMMENDATION

-

Set the contact on.
Connect the CLIP tester.
Is there any communication between the tester
and  E.C.U. decoder ?

Is the state 19D is ACTIVE?

Check the continuity and the isolation related
to the ground and to the + 12V of the wiring
between A6 decoder pin and injection
computer pin 58.
 Is the wiring good?

See ALP 1.

Check the  correct memorisation of
the  anti starting code by the  E.C.U.
decoder ; if not, replace the decoder.

Fix the electric wiring.

Perform the impulse detection test by means
of the CLIP tester connected to the E.C.U.
decoder A6 pin.
Set the  contact on and check impulses
presence.
Are there any impulses?

Replace the injection computer.

Replace E.C.U. decoder or see the “ Kit
replacement procedure “.

Perform a conformity checking.

ALP6. 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 and the isolation related to the ground
of the wiring between :
