RECOVERY PROCE-
The emergency procedures should be carried out, when it is not possible to start the engine with the keys available.
This procedure requires the possession of the Code Card; with the corresponding ELECTRONIC CODE (5-figure code written on the card). The procedure, (carried out either with the Alfa Tester or with the accelerator pedal) consists in entering the ELECTRONIC CODE directly in the injection control unit.
This procedure makes it possible to start the engine only once; the procedure must be repeated to start the engine again (or a "known" key must be inserted, i.e. already memorised in the control unit).
Emergency starting procedure (using the accelerator pedal)
This procedure should be carried out using the accelerator pedal and carefully watching the indications of the injection control unit warning light.
- Turn the key to MARCIA
- Press the accelerator pedal and keep it pressed until the warning light goes out.
- When the warning light goes out release the accelerator pedal.
- At this point the warning light begins to flash; after the number of flashes corresponding to the first number of the code on the Code Card (ELECTRONIC CODE) depress the accelerator pedal completely.
- The warning light turns on and stays on for 4 seconds then it goes out.
- When the warning light goes out, release the accelerator pedal
- The warning light starts to flash again, after the number of flashes corresponding to the second number of the ELECTRONIC CODE, press the accelerator fully home again.
- Proceed in the same way for the other numbers of the ELECTRONIC CODE.
- Also after the last number, keep the accelerator pressed until the warning light goes out (appr. 4 seconds)
- Release the accelerator pedal.
If the warning light flashes quickly, it means that the operation has been carried out correctly, thus the car can be started; if the warning light stays on, the code has not been entered correctly, move the key to STOP and back to MARCIA again, and repeat the procedure.
EXAMPLE: ELECTRONIC CODE = "42173"
NOTE: If this procedure is not activated correctly, check the throttle potentiometer and the corresponding wiring, and also the throttle itself (throttle stroke without obstacles or sticking); also check the supply to the C.C.M..
