FAILURES LOCATING BASED ON CLIENT CLAIM
(algorithm for damage locating)
A LP1. MISSING COMMUNICATION CLIP TESTER / E.C.U DECODER
RECOMMENDATION Check if the lines K a nd L are not perturbed by another computer
of the vehicle.
Check the condition of the F03, F04 fuses from cockpit fuse box.
Be sure the CLIP t ester is not the cause of t he failure, by trying the communication with
another computer of the vehicle.
Check the tension of the battery (U>12,3V). If it is necessary, charge the battery.
Check the correct c onnection of the E.C.U. decoder to the wiring.
Check the supply of the E.C.U. decoder : - mass at pin A8; - supply (+IC) at pin A9.
Be sure that the diagnostic socket is correctly supplied.
Check the continuity and the isolation of the electric wiring on the pins’ line corresponding to:
E.C.U. decoder A3 7 diagnostic socket
A4 15
If the dialogue CLIP tester – E.C.U. decoder cannot be established, then replace the decoder.
When the communication with the tester is established, solve the
AFTER REPAIRING failures displayed by CLIP.
Perform a conformity checking.

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 a nd check if t he indicator switches
off;
- if the anti starting system is turned off, connect
the pin A5 of t he 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 m emorised
failures.

RECOMMENDATION Check the absence of the failures with the CLIP tester. If there are failures, fix them first.
Check if the synchronisation of the RF remote control and the E.C.U. decoder has been
performed.
Are the turning lights functioning normally at the activation of the signalling switch ?
Check the continuity and the isolation
related to t he mass and the +12 V of the
