Diagnostic Codes
Check for active diagnostic codes on the electronic
service tool. Troubleshoot any active codes before
continuing with this procedure.
Electrical Connectors
1. Refer to Troubleshooting, "Electrical Connectors
- Inspect".
2. Repair the electrical connectors or replace the
electrical connectors.
3. Ensure that all the connector seals are in place
and that the connectors have been correctly
installed.
4. Ensure that the repairs have eliminated the fault.
If the fault has not been eliminated proceed to
"Fuel Supply".
Fuel Supply
1. Check the fuel pressure. Refer to Systems
Operation, Testing and Adjusting, "Fuel System
Pressure - Test".
2. Ensure that the fuel system has been primed.
Refer to Systems Operation, Testing and
Adjusting, "Fuel System - Prime".
3. Check the diesel fuel for contamination. Refer to
Systems Operation, Testing and Adjusting, "Fuel
Quality - Test".
4. Check for air in the fuel system. Refer to Systems
Operation, Testing and Adjusting, "Air in Fuel -
Test".
5. Check that the fuel lines are tight and secured
properly.
6. Check for fuel supply lines that are restricted.
7. Check the fuel filters.
8. Visually check the fuel tank for fuel. The fuel
gauge may be faulty.
9. If the engine has a water separator, check for
water in the fuel.
10. Ensure that the fuel supply valve (if equipped) is
in the full OPEN position.
11. If the temperature is below 0 °C (32 °F), check
for solidified fuel (wax).
Check the Intake Manifold Pressure
1. Use the electronic service tool to verify the intake
manifold pressure.
2. Turn the start switch to the ON position.
3. Check the intake manifold pressure. The pressure
should read 0 kPa (0 Psi).
4. Use the electronic service tool to check for the
following logged diagnostic codes:
•
102-03 Intake Manifold Pressure Sensor open
circuit or shorted high
•
102-04 Intake Manifold Pressure Sensor
shorted low
If either of these diagnostic codes are logged,
proceed to Troubleshooting, "Engine Pressure
Sensor Open or Short Circuit - Test".
5. If no faults are found proceed to "Air Intake and
Exhaust System".
Air Intake and Exhaust System
1. Check the air filter restriction indicator, if equipped.
2. Ensure that the air filter is clean and serviceable.
3. Check the air intake and exhaust systems 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. Ensure that the repairs have eliminated the
diagnostic code.
6. If the problem has not been eliminated, proceed
to "ECM Connection".
ECM Connection
1. Check that the J1/P1 connector is correctly
connected.
2. Verify the proper pin positions for the power
connections and the ground connections for the
Engine Control Module (ECM).
3. If a problem is suspected with the ECM power
and ground connections refer to Troubleshooting,
"Electrical Power Supply Circuit - Test".
