•
3-2 Cylinder #3 Injector Data Incorrect
•
4-2 Cylinder #4 Injector Data Incorrect
•
5-2 Cylinder #5 Injector Data Incorrect
•
6-2 Cylinder #6 Injector Data Incorrect
Expected Result 2
Three injectors that share a common supply indicate
a diagnostic code.
Note: Injectors 1, 2 and 3 share a common injector
driver circuit in the ECM. Injectors 4, 5 and 6 share a
common driver circuit in the ECM. If three injectors
that share a common supply indicate a diagnostic
code then this is probably caused by a faulty ECM.
Results:
•
OK – Result 1 One or more diagnostic codes are
logged. Proceed to Test Step 2.
•
OK – Result 2 Three injectors that share a
common supply indicate a diagnostic code.
Proceed to Test Step 3.
•
Not OK – No related diagnostic codes are logged.
STOP.
Test Step 2. Check the Faulty Cylinder
Numbers
A. Use the electronic service tool in order to make a
note of the logged diagnostic codes.
B. Use the noted diagnostic codes in order to check
the cylinders for faulty injectors.
Expected Result:
The diagnostic codes indicate the cylinder numbers
that have faulty injectors.
Results:
• OK – No related diagnostic codes are logged.
STOP.
•
Not OK – The diagnostic codes indicate the
cylinder numbers that have faulty injectors.
Repair: Replace the faulty injectors.
Use the electronic service tool in order to program
the replacement trim files for the injectors. Refer
to Troubleshooting, "Injector Trim File" for further
information.
Use the electronic service tool in order to clear the
logged codes.
This document is printed from SPI². Not for RESALE
Turn the keyswitch to the ON position.
Start the engine.
Use the electronic service tool in order to perform
the "Fuel System Verification - Test". If the cylinders
indicate "PASS", then the fault has been cleared.
Verify that the repair eliminates the fault.
STOP.
Test Step 3. Check the ECM
A. Make sure that the latest flash file for the
application is installed in the ECM. Refer to
Troubleshooting, "Flash Programming".
B. Contact Perkins Global Technical Support.
Note: This consultation can greatly reduce the repair
time.
C. If the Perkins Global Technical Support
recommends the use of a test ECM, install a test
ECM. Refer to Troubleshooting, "Replacing the
ECM".
D. Use the electronic service tool in order to perform
the "Fuel System Verification - Test.". Verify that
the test eliminates the fault.
Note: The "Fuel System Verification - Test" will
indicate if the cylinder has a "Pass" or "Fail". If the
cylinders indicate "Pass" then the fault has been
cleared.
E. If the test ECM eliminates the fault, reconnect the
suspect ECM.
F. Use the electronic service tool in order to perform
the "Fuel System Verification - Test".
Expected Result:
The test ECM clears the fault. Using the electronic
service tool in order to perform the "Fuel System
Verification - Test" with the suspect ECM indicates
a "FAIL" condition.
Results:
• OK – The test ECM eliminates the fault and the
suspect ECM indicates a "FAIL" condition. Replace
the faulty ECM. Verify that the repair eliminates the
fault.
Repair: Replace the ECM.
STOP.
•
Not OK – The test ECM did not eliminate the fault.
