Troubleshooting Section
Troubleshooting:
Monitor the con fi guration screen on the electronic
service tool in order to determine the type of speed
demand circuit that is used on the engine.
If the engine is equipped with an analog speed
demand circuit, proceed to “Test Step 1”.
If the engine is equipped with a digital speed demand
circuit, proceed to “Test Step 2”.
Test Step 1.
Perform the following diagnostic procedure: “Speed
Demand Circuit (Analog) - Test”
Results:
•
OK – STOP.
Test Step 2.
Perform the following diagnostic procedure: “Speed
Demand Circuit (Digital) - Test”
Results:
•
OK – STOP.
i02752019
CID 0091 FMI 08
Conditions Which Generate This Code:
The Electronic Control Module (ECM) detects the
following conditions:
•
The signal frequency from the digital speed
demand circuit is less than 150 Hz or the signal
frequency is greater than 1050 Hz for more than
two seconds.
•
The ECM has been powered for at least three
seconds.
•
Diagnostic code 0091-03 is not active.
•
Diagnostic code 0091-04 is not active.
System Response:
The ECM sets the “Throttle Position” to “0%”.
If equipped, the warning light will be on. The ECM
will trigger a snapshot. The diagnostic code will be
logged if the engine is running. The diagnostic code
will not be logged if the engine is cranking.
Possible Performance Effect:
The engine may remain at low idle while the
diagnostic code is active.
Troubleshooting:
This diagnostic code indicates that the frequency of a
digital throttle signal is out of the normal range.
Perform the following diagnostic procedure: “Speed
Demand Circuit (Digital) - Test”
Results:
• OK – STOP.
i02655609
CID 0100 FMI 03
Conditions Which Generate This Code:
The Electronic Control Module (ECM) detects the
following conditions:
•
The signal voltage from the engine oil pressure
sensor is greater than 4.95 Volts DC for more than
eight seconds.
•
The ECM has been powered for at least two
seconds.
•
The engine is not running or the engine coolant
temperature is greater than 38 °C (100 °F).
System Response:
The ECM will log the diagnostic code. If equipped,
the warning lamp will come on. The ECM will set data
for engine oil pressure to the default value.
Note: The engine oil pressure that is displayed on
the electronic service tool is the default value for
engine oil pressure. The default engine oil pressure
is 600 kPa (87 psi). The electronic service tool
will display “Voltage Above Normal” on the status
screens.
Possible Performance Effect:
None
