THE CONFORMITY CHECKING
N ext, the checking of different states and configurations of the anti starting system is to be
performed.
RECOMMENDATION In case of finding some failures at the diagnostic by means of
the CLIP tester, analyse them based on the diagnostic (ALP)
corresponding to the respective failure.
Crt. Function State/ configuration Obse rvations
Nr. 1. Conformity E.C.U decoder. Computer identification Display of the E.C.U. decoder item.
2. Remote control type 2G = remote control IR = infrared configuration RF = radio frequency

6. Forced starting protection 9D = forced protecting mode ACTIVE = only after validation on the blue button.
7. Anti starting state 10G = anti starting ACTIVE = with the contact
taken off or after 10 seconds

8. Key presence 8D = key present ACTIVE at the setting on
the contact if there is a
coded key.
REMARK: the states 8D,
9D, 10 D must be ACTIVE
at a correc t operation.
9. Code key receiving 9D = received key code ACTIVE at the setting on
the contact if the key is
coded in a good format.
10. Correct key code 10D = right key code ACTIVE at the setting on the contact if the key is
coded in a good format and
has the correct code.
REMARK: after the analyse
of the states 8D, 9D, 10 D
the contact will be set on
when the LED indicator
b links ( ACTIVE anti

OPERATION
When anti-starting system is on, the red LED is blinking (rare signal: one blink/sec).
After setting the contact on, the key code is transmitted to the Cockpit Central Unit.
If the code is recognized by the Cockpit Central Unit, this one is sending coded signals to the
injection computer and the anti-starting LED is off.
If signals issued by the Cockpit Central Unit and by the injection computer are matching, the
Cockpit Central Unit is authorizing the engine starting and the injection is unlocked.
SPECI AL SI TUATIONS
Injection computer does not have any reference code in m emory: the code sent by UCH is
written in the memory .
If there is no matching of the key c odes / Cockpit Central Unit, t he system is remaining
blocked and anti-star ting LED is blinking (quick signal). The vehicle starting is not authorized.
AT TE NT ION: when the battery is low charged, the voltage drop further to starter
action may reactivate the anti-starting. If voltage is too low, starting is impossible.
Key recognition in normal operation

Diagnostic – General
THE CODING OF THE INJECTION COMPUTER.
The injection c omputer i s delivered not coded. Therefore, t he anti-starting system code
memorizing will be necessary, when its mounting, in order to authorize the vehicle starting.
It is sufficient to set the contact on for fe w seconds, without starting the engine. Set the
contact off and the anti-starting function will be ensured after few seconds (anti-starting red
LED is blinking)
ATT E NT ION:
By means of this anti-star ting system, the vehicle is keeping its own anti-starting code on all
its lifetime. Furthermore, this system does not have a breakdown code. Therefore, it is forbidden
to perform tests with injection computers borrowed from warehouse that must be a fter that
returned. The code memorized by the injection computer can not be anymore erased.

RECOMMENDATIONS Nothing to notice
Check the communication of CLIP tester with a computer from another vehicle.
Check:
- connection between CLIP tester and the diagnostic socket (check the cable c ondition).
Cockpit and engine compartment fuses.
Check presence +1 2 volts befor e c ontact at pin 16, + 12 volts after contact at pin 1
and mass at pins 4 and 5 of the di agnostic socket
Fix it if necessary.
Connect the multi-socket and check the insulation, continuity and absence of parasite resis-
tance at connections:
Pin A3 of UCH connector P1 with 15 pins fuse box
Pin 22 of UCH connector E H1 with 40 pins + after contact
Pin A1 of UCH connector P1 with 15 pins mass
