CID 0004 FMI 06
Conditions Which Generate This Code:
This diagnostic code is designed to indicate a short
circuit (high current). The short circuit can be in
either the so
lenoid or the wiring for the electronic unit
injector for No. 4 cylinder.
The Electro
nic Control Module (ECM) detects the
following conditions:
•
Ahighcurr
ent condition (short circuit) for each of
five consecutive attempts to operate
•
Battery vo
ltage above 9 VDC for 2 seconds
System Response:
If equipped, the warning light will come on. The ECM
will log the diagnostic code.
Possible Performance Effect:
The engi
ne will 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
compar
ison with the other electronic unit injectors.
An electrical fault can prevent the electronic unit
injec
tor from 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
opera
ting. 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 b
een logged but a short circuit will prevent the
operation of the electronic unit injector.
Per
form the following diagnostic procedure: “Injector
Solenoid Circuit - Test”
Res
ults:
•
OK – STOP.

CID 0004 FMI 07
Conditions Which Gen erate This Code:
The electronic unit injector is no longer capable of
delivering the correct amount of fuel.
System Response:
If equipped
, the warning light will come on. The
Electronic Control Module (ECM) will log the
diagnostic code.
Possible Pe rformance Effect:
The engine
will be derated.
Troubleshooting:
Use the electronic service tool to perform the
Verification Test for the Fuel System. If the diagnostic
code is st
ill active, do the following procedure.
Replace the suspect electronic unit injector. Refer
to Disas
sembly and Assembly, “Electronic Unit
Injector - Remove” and Disassembly and Assembly,
“Electronic Unit Injector - Install”.
Use the electronic service tool to perform the
Verification Test for the Fuel System.
Perform the following diagnostic procedure: “None”
Resul
ts:
•
OK – STOP.

CID 0005 FMI 02
Cond
itions Which Gen erate This Code:
This diagnostic code is applicable to six cylinder
eng
ines only.
The Electronic Control Module (ECM) detects the
fol
lowing condition:
•
Data from the electronic unit injector for the No. 5
cy
linder is out of limits.
•
Diagnostic code 0168-01 is not active.
•
Diagnostic codes 0001-05 and 0001-06 are not
active.
