Diagnostic

ALP3. THE ANTI STARTING INDICATOR REMAINS PERMANENTLY LIGHTED
( even when the contact is taken off) OR IT REMAINS PERMANENTLY SWITCHED
OFF

RECOMMENDATION Check if the “Procedure E.C.U. decoder replacement” was

correctly performed

Check the fuse F03 condition from the cockpit
fuse box.
Is the fuse good?

Is there the failure “DOORS BLOCKING
CONTACT”.

Check the continuity and the isolation related
to the mass, between the pin A 5 of the E.C.U.
decoder and the dashboard.(pin 6 from black
connector)
Is the wiring good?

Replace the fuse.

Analyse this failure and replace.

Fix the wiring.

Perform the following tests in order to find the
damaged element:
- if the anti starting indicator is permanently
lighted, disconnect the connector of the E.C.U.
decoder and check if the indicator switches
off;
- if the anti starting system is turned off, connect
the pin A5 of the wiring connector from the
E.C.U. decoder to an electric mass and check
if the indicator turns on.
Are the answers affirmatives?

Replace the instrument panel.

Replace the E.C.U. decoder.

Perform a conformity checking.

AFTER REPAIRING

Check the operation of the anti starting system.
Remove by means of the CLIP tester the possible memorised

mass of the wiring between :
E.C.U. decoder

pin B8 actuators
Pin B9 doors

Is the wiring in good condition?

Fix the wiring.

Check the continuity and the isolation
related to the mass of the wiring between
E.C.U. pin B2 1 switch
decoder Pin B5 5 blocking doors
Is the wiring in good condition?

Repair.

Disconnect the E.C.U. decoder, then supply
the wiring connector with +12 V at pin B9
and the mass at the pin B8, than versa (+ 12
V at pin B8 and the mass at pin B9).
Are the actuators blocking/unlocking the
doors?

Damaged actuators.

Replace them.

Replace the E.C.U. decoder, then perform the “E.C.U. decoder

replacement procedure”.

Yes

AFTER REPAIRING
