ACCOUSTIC WARNING - ANTI STARTING

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.

Check state ET002 “received key code” and state ET003 “valid key code” with the contact on.
If states ET002 and ET 003 are “YES”, perform the injection computer diagnostic
If state ET002 is “NO”, handle with priority this state.
