i02655618
CID 0110 FMI 03
Conditions Which G enerate This Code:
The Electronic Control Module (ECM) detects the
following conditions:
•
The signal voltage from the engine coolant
temperature sensor is greater than 4.95 Volts DC
for more than e
ight seconds.
•
The ECM has been powered for at least two
seconds.
System Response:
If equipped, the warning light will be on. An active
diagnostic code will be generated after eight seconds.
The diagnost
ic code will be logged if the engine has
been operating for more than seven minutes.
The ECM will d
efault to 90 °C (194 °F) for engine
coolant temperature. “Voltage Above Normal” will
be displayed next to the status for “Engine Coolant
Temperatur
e” on the electronic service tool.
Possible Performance E ffect:
•
Poor stability
•
Poor cold ru
nning
•
White smoke
Troubleshooting:
Perform the
following diagnostic procedure: “Engine
Temperature Sensor Open or Short Circuit - Test”
Results:
•
OK – STOP.

CID 0110 FMI 04
Conditions
Which Generate This Code:
The Electronic Control Module (ECM) detects the
following c
onditions:
•
The signal voltage from the engine coolant
temperatu
re sensor is less than 0.2 Volts DC for
more than eight seconds.
•
The ECM has been powered for at least two
seconds.
•
Diagnostic code 0168-01 is not active.
System Response:
The ECM will de
fault to 90 °C (194 °F) for engine
coolant temperature. “Voltage Below Normal” will
be displayed next to the status for “Engine Coolant
Temperature”
on the electronic service tool.
If equipped, the warning light will come on. An active
diagnostic c
ode will be generated after eight seconds.
The diagnostic code will be logged if the engine has
been operating for more than seven minutes.
Possible Performance Effect:
•
Poor stabili
ty
•
Poor cold running
•
White smoke
Troubleshoo
ting:
Perform the following diagnostic procedure: “Engine
Temperature
Sensor Open or Short Circuit - Test”
Results:
•
OK – STOP.
i02655628
CID 0168 FMI 00
Conditions Which Generate This Code:
This condition indicates that the battery circuit to
the Electronic Control Module (ECM) has excessive
voltage whi
le the engine is running.
The ECM detects the following conditions:
•
For 24 Volt DC systems, the battery voltage to the
ECM exceeds 32 Volts for more than 0.5 seconds.
•
For 12 Volt DC systems, the battery voltage to the
ECM exceeds 16 Volts for more than 0.5 seconds.
•
The keyswitch is in the ON mode.
•
The engine
is not cranking.
•
The engine is running for more than 30 seconds.
