16 - The injector electric circuit is steady Repeat
the checks. If the fault persists, check the control
unit connector. If necessary, replace the electronic
control unit.
17 - Repeat the test using the resistance multime-
ter. Check the resistance between pin 13 and pin
87 (black/green cable) of the injection load remote
control.
13 - black/green = 14.5
Ω
± 5% (resistance of the
injector)
YES go to 19 NO go to 18
18 - No continuity. Disconnect the connector and
repeat the resistive check directly at the injector
terminals.
Resistance = 14.5
Ω
± 2%
YES go to 21 NO go to 22
19 - Check the earth insulation of the injector neg-
ative line. Disconnected control unit and injector
connectors.
13 - 23 =
Ω
infinite
NO go to 20
20 - Repair or replace the cable harness.
21 - Check the continuity between the injector
power supply connector (red - yellow) and pin 13.
Restore the continuity, if required, or replace the
wiring.
22 - Replace the injector.
