A LP1. MISSING COMMUNICATION CLIP TESTER / E.C.U DECODER
RECOMMENDATION Check if the lines K and L are not perturbed by another computer
of the vehicle.
Check the situation of the F15 fuse ( up to 01.06.2001) or F7 (after 01.06.2001)
Replace it if necessary.
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>10,5V). 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 : - ground 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
AFTER REPAIRING the failures displayed by CLIP.
Perform a conformity checking.

THE PIN CODE
The PIN code is formed of four figures and it can be used only for deactivating the anti intrusion
s ystem, if this operation can not be performed by pushing the deactivating button from the RF
remote control of the vehicle. For introducing the PIN code, perform as follows:-set on the contact key in the M position and take it off it for three times in seven seconds,
after which the anti intrusion LED indicator will switch on for three seconds; -set on the contact again on the M position and maintain it until the number of the L ED
blinks is e qual with the first figure of the PIN code, then take off the contact; -set on the contact in the M position and maintain it until the number of LED blinks is equal
w ith the second figure of the PIN code, then take off the contact;
-perform the above mentioned method in order to introduce the third and the fourth figure
of the PIN code;
-after that, the system is deactivated and the siren stops automatically;
- set on the contact again – the anti LED indicator must switch on, confirming in this way
that the c orrect introduction of the PIN code.
AT TENT ION
If it i s necessary the checking of the PIN code, t his will be pe rformed
only after al least 20 seconds have passed, since the anti intrusion ECU has been
connected to the vehicle’s wiring or since the connecting of t he vehicle’s battery.
The COBRA anti intrusion system can operate in t hree different modes (2,3 or 4).
For the Super Nova vehicles, the system has been programmed to work in the second operation
mode. If by mistake the PIN code was introduced in less than 20 seconds since the battery
connecting or since connecting the anti intrusion ECU, this can involve the change of the operation
way of the system, which will generate errors during the operation. There is, although, the possibility
of reprogramming the correct operation way (type 2) and in this purpose, perform the following
operations : - disconnect and then reconnect the anti intrusion ECU; when connecting the anti intrusion
ECU the anti intrusion LED indicator will switch on once, confirming the correct connecting;
-af ter at least 5 seconds from the previous operation, but no more than 20 second from it,
perform the following operation s:
-s et on the contact key in the M position for three times and then release it;
- the anti intrusion LED indicator will switch on for three seconds and then will switch off;
- set on again the contact key in the “M” position and maintain it, counting two blinks of the
anti intrusion LED indicator, then take off the contact;
- the LED indicator will blink for two times in two series, confirming in this way the proper
performance of the previous operations;
press the doors locking button of the dashboard, in order to lock and unlock the doors; the anti
intrusion LED indicator must not blink;
