NOTES AND FEATAURES OF THE SYSTEM

The anti-theft system is capable of signalling any faults in the system to the Owner by the LED coming on constantly or flashing:

A. During switching on:

  • LED on constantly to indicate faults in the volumetric sensor circuits
  • LED on intermittently, slow speed, to indicate faults in the door and lid switches
  • LED on intermittently, fast speed, to indicate fault in the anti-theft device control unit

B. During switching off:

  • impulse cycles (number of impulses from 1 to 100) to indicate the cause of the operation of the anti-theft device (see de-coding in table 2, page 84).

If the LED signals problems, the Owner should seek assistance from the Fiat Service Network.

The system is equipped with a special diagnostic socket for connection with the FIAT/LANCIA Tester and memory module M29-A (see explanatory notes in I.S. n° 7-8/93).

It should be remembered that during service operations to the vehicle or in the case of problems with the anti-theft system that activate the alarm, it can be excluded by turning the switch on the control unit from the ON position to the OFF position.

When this operation is completed, always return the switch to the ON position and always re-tight-en the protective cap on the control unit.

It should be borne in mind that each individual component (in the anti-theft system) fitted on the vehicle becomes an integral part of it and should not be fitted or tested on other vehicles, even if they are the same model.
