System Operation Description:
Use this procedure under the following conditions:
Use this procedure for any of the following diagnostic codes:
• 1-2 Cylinder #1 Injector Data Incorrect
• 2-2 Cylinder #2 Injector Data Incorrect
• 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

The following background information is related to this procedure:
The engine has electronic unit injectors that are electronically controlled. The Electronic Control
Module (ECM) sends a 70 volt pulse to each injector solenoid. The pulse is sent at the correct time and for the correct duration for a given engine load and engine speed. Use this procedure to identify the cause of the diagnostic code. Use this procedure to repair the system.
If an injector is replaced, then the correct trim file for the injector must be programmed into the ECM.
The trim files for the injectors allow each individual injector to be fine tuned for optimum performance.
The ECM will generate the following diagnostic code if the trim files for the injectors are not programmed:

253-2 Personality Module mismatchIf the ECM is replaced then the replacement ECM must be correctly programmed. Refer to
Troubleshooting, “Replacing the ECM” for further information.
Use the electronic service tool in order to perform the “Fuel System Verification – Test.”. The “Fuel System Verification – Test.” is used to check that the system operates correctly after a repair has been made.

Test Step 1. Check for Diagnostic Codes
That Are Related to this Procedure.
A. Connect the electronic service tool to the diagnostic connector.
B. Turn the keyswitch to the ON position.
C. Check for logged diagnostic codes that are related to this procedure.
D. Make a note of the logged diagnostic codes.

Expected Result:
Expected Result 1
One or more of the following diagnostic codes are logged:
• 1-2 Cylinder #1 Injector Data Incorrect
• 2-2 Cylinder #2 Injector Data Incorrect

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.
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 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.

Repair: Repeat the test procedure from Test Step 1.
STOP.
