Troubleshooting Section
•
A low current condition (open circuit) for each of
five consecutiv
e attempts to operate
•
Battery voltage is higher than 9 VDC for 2 seconds.
System Response:
If equipped,
the warning light will come on. The ECM
will log the diagnostic code.
Possible Pe
rformance Effect:
The engine will have low power and/or rough running.
Troubleshooting:
When an inj
ector cutout test is performed, a faulty
electronic unit injector will indicate a low reading in
comparison with the other electronic unit injectors.
An electrical fault can prevent the electronic unit
injector from operating. An open circuit in the wiring
that is un
ique to the e lectronic unit injector will prevent
that individual electronic unit injector from operating.
An open circuit in common wiring within the ECM can
prevent t
he three electronic unit injectors that share
that common wiring from operating.
The ECM w
ill continue to attempt to operate the
electronic unit injector after the diagnostic code has
been logged but an open circuit will prevent the
operati
on of the electronic unit injector.
Perform the following diagnostic procedure: “Injector
Soleno
id Circuit - Test”
Results:
•
OK – STOP.

Conditions Which Generate This Code:
This diagnostic code is designed to indicate a short
circuit (high current). The short circuit can be in
eit
her the solenoid or the wiring for the electronic unit
injector for No. 3 cylinder.
The
Electronic Control Module (ECM) detects the
following conditions:
•
Ah
igh current condition (short circuit) for each of
five consecutive attempts to operate
•
Ba
ttery voltage above 9 VDC for 2 seconds
System Response:
If equipped, the warning light will come on. The ECM
will log the diagnostic code.
Possible Pe rformance Effect:
Theenginewi
ll have low power and/or rough running.
Troubleshooting:
When an injector cutout test is performed, a faulty
electronic unit injector will indicate a low reading in
comparison
with the other electronic unit injectors.
An electrical fault can prevent the electronic unit
injector f
rom operating. A short circuit in the wiring or
the ECM that is unique to one electronic unit injector
will prevent that individual electronic unit injector from
operating
. A short circuit in common wiring within the
ECM can prevent the three electronic unit injectors
that share that common wiring from operating.
The ECM will continue to attempt to operate the
electronic unit injector after the diagnostic code
has been l
ogged but a short circuit will prevent the
operation of the electronic unit injector.
Perform
the following diagnostic procedure: “Injector
Solenoid Circuit - Test”
Results
:
•
OK – STOP.

CID 0003 FMI 07
Condi
tions Which Generate This Code:
The electronic unit injector is no longer capable of
deli
vering the correct amount of fuel.
System Response:
If equipped, the warning light will come on. The
Electronic Control Module (ECM) will log the
dia
gnostic code.
Possible Pe rformance Effect:

Tr
oubleshooting:
Use the electronic service tool to perform the
Ve
rification Test for the Fuel System. If the diagnostic
code is still active, do the following procedure.
