CID 0006 FMI 07
Conditions Which Generate This Code:
This diagnostic code is applicable to six cylinder
engines only.
The electronic unit injector is no longer capable of
delivering the correct amount of fuel.
System Response:
If equippe
d, the warning light will come on. The
Electronic Control Module (ECM) will log the
diagnostic code.
Possible Performance Effect:
The engin
ewillbederated.
Troubleshooting:
Use the electronic service tool to perform the
Verification Test on the fuel system. If the diagnostic
code is s
till 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 on the fuel system.
Perform the following diagnostic procedure: “None”
Resul
ts:
•
OK – STOP.

CID 0041 FMI 03
Con
ditions Which Generate This Code:
The Electronic Control Module (ECM) detects the
fol
lowing conditions:
•
The 8 V supply is more than 8.8 VDC for more
th
an one second.
•
The ECM has been powered for more than 3
se
conds.
System Response:
The ECM will log the diagnostic code and the
diagnostic lamp will illuminate while this diagnostic
code is active
.
Possible Pe rformance Effect:
Theenginemaybelimitedtolowidle.
Note: The8V
supply provides power to the two
speed/timing sensors.
Troublesho
oting:
Perform the following diagnostic procedure: “Engine
Speed/Tim
ing Sensor Circuit - Test”
Results:
•
OK – STOP.

CID 0041 FMI 04
Conditions Which Gen erate This Code:
The Electronic Control Module (ECM) detects the
following conditions:
•
The 8 V supply is less than 7.2 VDC for more than
one second.
•
The ECM has been powered for more than 3
seconds.
•
Diagnostic code 0168-01 is not active.
Syste
m Response:
The ECM will log the diagnostic code and the
diag
nostic lamp will illuminate while this diagnostic
code is active. An active diagnostic code may not
cause any noticeable effect on engine response
unle
ss the voltage drops below 6.5 VDC.
Possible Pe rformance Effect:
Theenginemaybelimitedtolowidle.
Not
e: The 8 V supply provides power to the two
speed/timing sensors.

oubleshooting:
Perform the following diagnostic procedure: “Engine
