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

DIAGNOSTICS INSTRUMENT: ACTIVATION
Coil 1:
The injection relay (No. 33 in the wiring diagram, placed under the saddle, next to the battery positive
CHECK, however, the identification of the relay with the colour of the cables) is energised for 5 seconds
and the brown/yellow cable of the coil is closed to ground for 2 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.
Coil 2:
The injection relay (No. 33 in the wiring diagram, placed under the saddle, next to the battery positive
CHECK, however, the identification of the relay with the colour of the cables) is energised for 5 seconds
and the brown/red cable of the coil is closed to ground for 2 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.
Coil 3:
The injection relay (No. 33 in the wiring diagram, placed under the saddle, next to the battery positive
CHECK, however, the identification of the relay with the colour of the cables) is energised for 5 seconds
and the brown/green cable of the coil is closed to ground for 2 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.
