145 electrical system diagnosisProtected programming
In this programming mode as many codes as required are recognised, but only the last four are memorised. Proceed as follows:
  1. press button D on the ceiling light: LED C flashes; NOTE: if the led does NOT flash, check that the alarm system is de-activated or that the receiver on the ceiling lamp is correctly powered.
  2. keeping the receiver button D pushed, press the transmitter button B, point it towards the receiver, but at least 20 cm. from it: the led of transmitter A, must flash no more than once;
  3. LED C lights continuously indicating that the code has been memorised: at this point the operator can release button D to end programming.
In the 3 sec. following the release of the button, it is possible to programme the country code to suit the country in which the car will be used. This is performed by pressing in quick succession the button of the receiver D, as shown in table 3. If the button is not pressed, the country code defaults to E.E.C. In the event of further memory storage operations, the last one remains in the memory. If the procedure has been carried out correctly, the LED on receiver C will flash 6 times, indicating that the code has been memorised on both the ceiling light receiver and in the control unit, if not, LED C will flash 18 times and it will be necessary to repeat the entire procedure starting from point 1 of simplified programming, after checking the correct connection between the control unit and the ceiling lamp

(*) Not used in this country, for versions without ALFA ROMEO CODE, because in this country a specific control unit with a special operating logic is foreseen. As it is not easy to carry out this procedure in such a short time as 3 seconds, a different procedure for entering the Country code is recommended. To do this, proceed as follows:
  • open the bonnet;
  • turn the ignition key from MARCIA to STOP: within 15 seconds the bonnet button must be pressed 7 times in quick succession in less than 10 seconds; 5 beeps will indicate entry in MANUAL DIAGNOSIS (see FAULT-FINDING). During these 5 beeps press the bonnet switch once again. A last long beep will signal the acceptance of this new operation;
  • keep the button pressed throughout the duration of the long beep. The latter signals entry into the country programming mode, thus the possibility to enter the country code;
  • release the switch and press it within 10 seconds the number of times mentioned in table 3 to select the operating mode of the country required (each press will have a feedback beep).
N.B. To enter another remote control repeat the operations from point 1 of simplified programming, provided that the memory has been "locked" as described below.

PROTECTED PROGRAMMING

To prevent unauthorised persons from entering their own code, it is necessary to protect ("lock") the memory; this operation takes place automatically after 256 activations/deactivations of the alarm system, or by entering the password (locking the memory manually).

Locking the memory manually

Protected programming can be entered by the Owner by entering the Password (four digit code on the transmitter label) before 256 activations/deactivations (for example on a new car during pre-delivery, when all the codes of the remote controls given to the Customer have been entered). To enter the Password:
  1. Press the button on receiver D for aprx. 2 seconds; LED C will flash for the whole time in which the button is pressed.
  2. Release button D: after aprx. 2 seconds LED C will flash once indicating the possibility to enter the first digit of the password.
  3. Press the button of the receiver D the number of times corresponding to the first figure of the password (for example if the Password is 5.2.0.3. press 5 times). Each time the button is pressed LED C lights up briefly to confirm;
  4. After aprx. 2 seconds from the last press on button D (the fifth in the example) led C will flash again to ask for the next figure.
