Disconnect the connector between the vehicle system and the fuel injection system.
Disconnect the connector to the control unit.
The electrical circuit of the injector is continuous.
Repeat checks.
If the anomaly persists check the control unit connector.
If necessary replace the control unit.
NO
Check resistance between pin 13 and the terminal
of the black-green wire on the connector fuel
injection system side.
13-black-green = 14.5Ω ± 5% (injector resistance)
NOYES
There is no continuity
Disconnect the connector and repeat resistance
controls directly on the injector terminals.
Resistance =14.5Ω ± 2%
Check continuity of the black-green wire in
the vehicle system section.
Check the connector accurately between
vehicle system and fuel injection system.
Repair or replace the harness.
Check the earthing
isolation of the negative
wire of the injector.
Control unit and injector
connectors disconnected
13-23 = Ω infinity
Repair or replace the
