Front injector
The auxiliary injection relay (No. 40 in the wiring diagram, placed under the fuel tank, right side, second
relay starting from the front; CHECK, however, the identification of the relay with the colour of the cables)
is energised for 5 seconds and the grey/green cable of the injector is closed to ground for 4 ms per
second. Disconnect the 4-way connector of the fuel pump to be able to hear the relay and injector
activation. The continuity of the wiring is necessary for correct activation: no error indications are dis-
played in case of lack of activation.
Rear injector
The auxiliary injection relay (No. 40 in the wiring diagram, placed under the fuel tank, right side, second
relay starting from the front; CHECK, however, the identification of the relay with the colour of the cables)
is energised for 5 seconds and the grey/red cable of the injector is closed to ground for 4 ms per second.
Disconnect the 4-way connector of the fuel pump to be able to hear the relay and injector activation.
