4. If the repair does not eliminate the fault proceed to
"Check the Fuel Injection Nozzles".
Examples of low compression are shown in the
following list:
•
Mechanical problem
•
Faulty piston rings
•
Worn cylinder bores
•
Worn valves
•
Faulty cylinder head gasket
•
Damaged cylinder head
Check the Fuel Injection Nozzles
1. Remove the fuel injection nozzles from the cylinder
head. Refer to Disassembly and Assembly, "Fuel
Injection Nozzle - Remove".
2. Check the fuel injection nozzles. Refer to Testing
and Adjusting, "Fuel Injection Nozzle - Test".
3. Ensure that the repairs have eliminated the
problems.
4. If the problem has not been eliminated,proceed to
"Check the Turbocharger (if equipped)".
Check the Turbocharger (if equipped)
Note: The turbochargers that are equipped on 1100
Series are nonserviceable items. If any mechanical
fault exists then the turbocharger must be replaced.
1. Ensure that the mounting bolts for the turbocharger
are tight.
2. Check that the turbocharger drain is not blocked
or restricted.
3. Check that the turbocharger housing is free of dirt
and debris.
4. Check the turbocharger for worn bearings. Refer
to Systems Operation, Testing and Adjusting,
"Turbocharger - Inspect". The turbochargers that
are equipped to 1100 series engines are not
serviceable. If any mechanical fault exists then the
turbocharger must be replaced.
5. Check that the turbine blades rotate freely on the
turbocharger. Refer to Systems Operation, Testing
and Adjusting, "Turbocharger - Inspect".
6. Ensure that the wastegate on the turbocharger is
adjusted correctly. Refer to Systems Operation,
Testing and Adjusting, "Turbocharger - Inspect".
The adjustment of the wastegate is set at the
factory. If adjustment of the wastegate is required
then the turbocharger must be replaced.
7. Make all necessary repairs to the engine.
8. Ensure that the repairs have eliminated the faults.
9. If the fault has not been eliminated proceed to
"ECM Parameters".
ECM Parameters
1. Ensure that the problem is not a programmed
parameter.
2. Use the electronic service tool in order to ensure
that the correct mode was selected.
3. Use the electronic service tool to verify the correct
engine rating for the engine.
4. Use the electronic service tool to verify the
maximum engine speed limit.
5. Use the electronic service tool to reset the
parameters to the OEM specifications.
6. Ensure that the repairs have eliminated the
performance problems.
7. If the repairs have not eliminated the faults
proceed to "Check Intake Manifold Pressure".
Check Intake Manifold Pressure (Engines
that are turbocharged)
1. Turn the start switch to the ON position.
2. Use the electronic service tool to observe the
intake manifold pressure. The intake manifold
pressure should be 0 kPa (0 psi).
