CAUTION
BEFORE CARRYING OUT ANY TROUBLESHOOTING,
CAREFULLY READ THE GENERAL TROUBLESHOOTING
CONCEPTS FOR ELECTRICAL DEVICES AT THE BEGIN-
NING OF THE CHECK AND CONTROL SECTION IN THE
ELECTRICAL SYSTEM CHAPTER.
DIAGNOSIS INSTRUMENT: ACTIVATION
Lower injector cylinder 1
•
The injection relay (No. 33 in the wiring diagram, placed under saddle, right side; CHECK,
however, the identification of the relay with the colour of the cables) is energised for 5 sec-
onds and the injector cable connected to control unit 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 displayed in case of lack of activation
Upper injector cylinder 2
•
The injection relay (No. 33 in the wiring diagram, placed under saddle, right side; CHECK,
however, the identification of the relay with the colour of the cables) is energised for 5 sec-
onds and the injector cable connected to control unit 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 displayed in case of lack of activation
