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.
Internal rear cylinder injector
•
The auxiliary injection relay (No. 46 in the wiring diagram, placed in the front relay box, left
side; CHECK, however, the identification of the relay with the colour of the cables) is ener-
gised for 5 seconds 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.

DIAGNOSTICS INSTRUMENT: ELECTRICAL ERRORS
External front cylinder injector P0201
•
short circuit to positive/ short circuit to negative / open circuit
Error cause
•
If shorted to positive: excessive voltage has been detected at PIN 8. If shorted to negative:
no voltage has been detected. If the circuit is open: an interruption has been detected.
Troubleshooting
•
If shorted to positive: disconnect the injector connector, set key to ON, activate the compo-
nent with the diagnosis instrument and check the voltage on the white/green cable on the
injector connector. If following the activation the voltage does not drop, restore the cabling,
otherwise replace the injector.
