Cid 0006 Fmi 07; Cid 0041 Fmi 03 - Perkins NJ Series Troubleshooting Manual

SENR9982-01
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 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
operating. On four cylinder engines, a short circuit
in common wiring within the ECM can prevent the
two electronic unit injectors that share that common
wiring from operating. On six cylinder engines, 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 logged 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 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 equipped, the warning light will come on. The
Electronic Control Module (ECM) will log the
diagnostic code.
Note: The diagnostic code can be viewed on the
electronic service tool.
Possible Performance Effect:
The engine will be derated.
Troubleshooting:
Use the electronic service tool to perform the Fuel
System Verification Test. If the diagnostic code is still
active, do the following procedure.
Replace the suspect electronic unit injector. Refer
to Disassembly and Assembly, "Electronic Unit
Injector - Remove" and Disassembly and Assembly,
"Electronic Unit Injector - Install".
Use the electronic service tool to perform the fuel
system verification test.
Perform the following diagnostic procedure: "None"
Results:
• OK – STOP.

CID 0041 FMI 03

Conditions Which Generate This Code:
The Electronic Control Module (ECM) detects the
following conditions:
•
The 8 volt supply is more than 8.8 VDC for more
than one second.
• The ECM has been powered for more than three
seconds.
i02489586
System Response:
The ECM will log the diagnostic code and the check
engine lamp will illuminate while this diagnostic code
is active.
Possible Performance Effect:
The engine may be limited to low idle.
Note: The 8 volt supply may provide power to the
digital throttle position sensor.
Note: The 8 volt supply provides power to the two
speed/timing sensors.
Troubleshooting:
Perform the following diagnostic procedure: "Digital
Throttle Position Sensor Circuit - Test"
Results:
• OK – STOP.
