Detach the connector from the ECU and check the

following:

- Presence of battery potential difference between

terminal 4 (Red/Blue) and earth

- Presence of battery potential difference between

terminals 4 (Red/Blue) and 8 (black), as shown in

the figure.

- Presence of battery potential difference between

terminals 5 and 8 with the key-switch onto «ON».

If no anomalies are found, replace the electronic

control unit.

Virgin circuit

If the ignition system has not been programmed,

the engine can be started but it will run limited to

2000 rpm. When trying to accelerate, some evi-

dent loss of power may be felt.

Program the system with the MASTER (Brown)

and SERVICE (Blue) keys as follows:

- Insert the MASTER key, turn it to "ON" and keep

it in that position for 2 seconds (limit values: 1 ÷ 3

seconds).

- Alternatively insert all the available black keys

and turn each one of them to "ON" for 2 seconds.

- Insert the MASTER key again and turn it to "ON"

for 2 seconds.

The maximum time to change keys is 10 seconds.

A maximum of 7 service keys (blue) can be pro-

grammed at one time.

Sequence and times must be strictly observed or

it will be necessary to repeat the procedure from

the start.
