Electrical Test
Safety lanyard must be on DESS post.
Using the vehicle communication kit (VCK) with
the B.U.D.S. software, energize the fuel injector
from the
Activation
section.
If the injector does not work, disconnect the plug
connector from the injector.
Install a temporary connector to the injector with
wires long enough to make the connection out-
side the bilge and apply voltage (12 V) to this test
harness.
This will validate the injector mechanical and elec-
trical operation.
If it does not work, replace it.
Using B.U.D.S., activate injector while probing pin
2 (of injector on harness side) and battery ground.
a. If 12 V is read, check continuity of circuit as per
following table. If it is good, try a new EMS ECU.
b. If it does not read 12 V, check continuity of cir-
cuit as per following table. If it is good, try a new
MPEM.
Otherwise, check the resistance of the fuel injec-
tor circuit.
Reconnect
the injector and disconnect the EMS
ECU connector A EMS ECU.
Using a multimeter, check resistance value be-
tween terminals as follows.
ENGINE CONNECTOR
EMS ECU CONNECTOR
The resistance should be between 11.4 and 12.6
Ω
.
If resistance value is correct, try a new EMS ECU.
Refer to EMS ECU REPLACEMENT procedures
elsewhere in this section.
If resistance value is incorrect, repair the wiring
harness/connectors or replace the wiring harness
between EMS ECU plug connector and fuel injec-
tor.
