DA-33 2/1 (PTO external)
DA-14 1/2 (MAG internal)
DA-30 2/2 (PTO internal)
If it is good, check the resistance of the fuel injec-
tor circuit.
Resistance Test
Disconnect the injector from the wiring harness
and check the resistance of the injector itself.
The resistance should be around 14.5
.
If resistance value is incorrect, replace the injector.
Reconnect the injector and disconnect the con-
nector A from the ECM as well as the engine con-
nector.
Using a multimeter, check resistance value be-
tween terminals as shown in the table below.

If resistance value is correct, try a new ECM. Refer
to ECM REPLACEMENT procedures elsewhere in
this section.
NOTE: Check if wiring harness shows any signs
of scoring prior to replace the ECM.
If resistance value is incorrect, repair the wiring
harness/connectors or replace the wiring harness
between ECM connector and fuel injector.
Fuel Injector Replacement
Removal
Before removing the injectors, the fuel rail has to
be removed from the engine. Refer to REMOVAL
in FUEL RAIL REPLACEMENT for the procedure.
