7. 11 STATE: OPERATE THE RF REMOTE CONTROL / GOOD RF SIGNAL
INDICATION
Do not access the following diagnostic
unless the state 11D
RECOMMENDATION becomes ACTIVE when operating the RF remote control. Check if the keys belong to the vehicle in question.
There is a desynchronising between the code of the RF remote control and the E.C.U. decoder
if at the activation of the remote control, the 111D state remains PASSIVE and the state 11G
becomes AC TIVE for 3 seconds, then becomes PASSIVE. The blocking / unlocking of the
do ors is not possible in this case.
Apply the corresponding procedure of resynchronisation (for one or two keys).
AFTER REPAIRING Perform a conformity checking.
Check the operation of the anti starting system.

wiring on the line
E.C.U. decoder Pin B2 pole 1 door locking switch. Pin B5 pole 3
Fix the electric wiring if necessary or replace the switch.

ALP3. THE ANTI STARTING INDICATOR REMAINS PERMANENTLY LIGHTED
(even when the contact is taken off) OR IT REMAINS PERMANENTLY SWITCHE D OFF.
RECOMMENDATIONCheck if the “Procedure E.C.U. decoder replacement” was correctly
performed.
Check the fuse F15 ( up to 01.06.2001) or
F07 (after 01.06.2001).
Is the fuse good?
Is there the failure “ DOORS’ LOCKING
CONTACT”?
Check the continuity and the isolation related
to the ground, between t he pin A 5 of the
E.C.U. decoder and the dashboard.
Is the wiring good?
Replace the fuse.
Analyse this failure and replace.
Fix the wiring.
Perform the following tests in order to find the
failure 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,
c onnect the pin A5 of the wiring connector from
the E.C.U. decoder to an electric ground 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 possibl e memorised failures.
