Recommended Actions
NOTICE
Do not crank the engine continuously for more than
30 seconds. Allow the starting motor to cool for two
minutes before cranking the engine again.
Diagnostic Codes
Check for active diagnostic codes on the electronic
service tool. Troubleshoot any active codes before
continuing with this procedure.
ECM Parameters
1.
Use the electronic service tool to make sure that
the FLS and FTS parameters have been correctly
entered.
2.
Use the electronic service tool to ensure that the
correct mode was selected.
3.
Use the electronic service tool to verify that the
correct engine rating has been provided.
4.
Use the electronic service tool to verify the
maximum engine speed limit.
5.
Ensure that the repairs have eliminated the
performance problems.
6.
If the repairs have not eliminated the faults
proceed to “Electrical Connectors”.
Electrical Connectors
1.
Turn the keyswitch to the ON position.
2.
Use the electronic service tool to verify that
the intake manifold pressure is 0 ± 0.5 kPa
(00 ± 0.070 psi). Check the 5 V sensor supply
for the intake manifold pressure. Refer to
Troubleshooting, “5 Volt Engine Pressure Sensor
Supply Circuit - Test”.
3.
Use the electronic service tool to verify the throttle
position status.
4.
Run the engine until the speed is equal to the
maximum no-load speed.
5.
Use the electronic service tool to make sure that
the throttle is set to reach the maximum no-load
speed.
6.
If the maximum no-load speed can not be obtained
refer to Troubleshooting, “Throttle Switch Circuit
- Test” and Troubleshooting, “Mode Selection
Circuit - Test”.
7.
If the engine speed is erratic refer to
Troubleshooting, “Analog Throttle Position Sensor
Circuit - Test” or Troubleshooting, “Digital Throttle
Position Sensor Circuit - Test”.
8.
If the fault has not been eliminated, proceed to
“Air Intake and Exhaust System”.
Air Intake and Exhaust System
1.
Check the air
fi
lter restriction indicator, if equipped.
2.
Ensure that the air
fi
lter is clean and serviceable.
3.
Check the air intake and the exhaust system for
the following defects:
•
Blockages
•
Restrictions
•
Damage to the air intake and exhaust lines and
hoses
4.
Make all necessary repairs to the engine.
5.
If the fault has not been eliminated, proceed to
“Valve Lash”.
Valve Lash
1.
Check the valve lash and reset the valve lash, if
necessary. Refer to Testing and Adjusting, “Engine
Valve lash - Inspect and Adjust”.
2.
If the repair does not eliminate the fault proceed
to “Turbocharger”.
Turbocharger
Note:
The turbocharger that is installed on this
engine is a nonserviceable item. If any mechanical
fault exists, except for the wastegate actuator, then
the turbocharger must be replaced. The wastegate
actuator can be replaced.
1.
Ensure that the mounting bolts for the turbocharger
are tight.
2.
Check that the oil drain for the turbocharger is not
blocked or restricted.
