Troubleshooting Section
System Response:
The ECM will log the diagnostic code. If equipped,
the warning lamp may come on.
Possible Performance Effect:
None
Troubleshooting:
Perform the following diagnostic procedure: “Ignition
Keyswitch Circuit and Battery Supply Circuit - Test”
Results:
•
OK – STOP.
i02655562
CID 0168 FMI 01
Conditions Which Generate This Code:
This code indicates that the battery circuit for the
Electronic Control Module (ECM) has low voltage
while the engine is running. If battery voltage
disappears without returning, the ECM will not log
this diagnostic code and the engine will shut down.
The ECM detects the following conditions:
•
The keyswitch is in the ON position.
• The engine is not cranking.
•
The engine is running for more than three seconds.
•
For 24 Volt DC systems, the battery voltage to the
ECM is below 18 Volts for more than 0.5 seconds.
•
For 12 Volt DC systems, the battery voltage to the
ECM is below 9 Volts for more than 0.5 seconds.
System Response:
The ECM will log the diagnostic code.
The engine will derate 100 percent.
If equipped, the warning lamp may come on.
Possible Performance Effect:
The engine may experience changes in the engine
rpm, and intermittent engine shutdowns or complete
engine shutdowns while the conditions that cause
this diagnostic code are present.
Troubleshooting:
Perform the following diagnostic procedure: “Ignition
Keyswitch Circuit and Battery Supply Circuit - Test”
Results:
•
OK – STOP.
i02655633
CID 0168 FMI 02
Conditions Which Generate This Code:
This condition indicates that the battery circuit for
the Electronic Control Module (ECM) is intermittent
while the engine is running. If the battery voltage
disappears without returning, the ECM will not log
this diagnostic code and the engine will shut down.
The ECM detects the following conditions:
•
Three voltage readings that are below 6 Volts DC
in a period of seven seconds will be detected by
the ECM. The voltage must subsequently increase
to more than 9 Volts DC.
• The keyswitch is in the ON position.
•
The engine is running.
•
The engine is not cranking.
System Response:
The ECM may stop injecting fuel. This may be
dependent on the length of time of the occurrence
of the fault.
The check engine lamp and the warning lamp may
come on as if the keyswitch was just turned on and
the engine started.
Possible Performance Effect:
The engine may experience changes in the engine
rpm, and intermittent engine shutdowns or complete
engine shutdowns while the conditions that cause
this diagnostic code are present.
Troubleshooting:
Perform the following diagnostic procedure: “Ignition
Keyswitch Circuit and Battery Supply Circuit - Test”
Results:
• OK – STOP.
