The following background information is related to this procedure:Injector codes are 30 hexadecimal character codes that are supplied with each injector. The code is on a plate on the top of the injector and a card is also included in the packaging for the injector. The code is used by the ECM to balance the performance of the injectors.Refer to Troubleshooting, "Injector Code - Calibrate" for further information.

Troubleshooting Test Steps Values Results
1. Check for Active Diagnostic Codes
A. Connect the electronic service tool to the diagnostic connector.
B. Turn the keyswitch to the ON position.
C. Check for active diagnostic codes or recently logged diagnostic codes.
Diagnostic codes
Result: No diagnostic codes are present.
Return the unit to service.
Result: One or more of the preceding diagnostic codes are active.
Make a note of any cylinder numbers with the active diagnostic code. Proceed to Test Step 2.
2. Check the Injector Code on any Suspect Cylinders
A. Connect the electronic service tool to the diagnostic connector. Refer to Troubleshooting, "Electronic Service Tools".
B. Turn the keyswitch to the ON position.
C. Select the following menu options on the electronic service tool to obtain the injector codes from the ECM:
"Service"
"Calibrations"
"Injector Codes Calibration"
D. Make a note of the injector codes for any suspect cylinders.
Diagnostic code
Result: The card that was supplied with the injector is available for the suspect cylinders.
Repair: Compare the injector code from the card with the injector code that was recorded from the electronic service tool for each suspect cylinder.
If the codes match, proceed to Test Step 3.
If the codes do not match, then use the electronic service tool to input the correct injector code. Refer to Troubleshooting, Injector Code - Calibrate.
Result: The card with the injector code is not available.
Proceed to Test Step 3.
3. Manually Program the Injector Code
A. Remove the valve mechanism cover. Refer to Disassembly and Assembly, "Valve Mechanism Cover - Remove and Install".
B. Make a note of the injector code that is on the injector in any suspect cylinders.
Note: Refer to Illustration 2 for the correct sequence for recording the injector code.
C. Compare the injector code from the injector with the injector code from the electronic service tool for each suspect cylinder.
Injector codes
Result: The code on the injector is the same as the code in the ECM. The injector is incorrect for the engine.
Repair: Replace the injector with the correct injector for the engine. Refer to Disassembly and Assembly, "Electronic Unit Injector - Remove" and refer to Disassembly and Assembly, "Electronic Unit Injector - Install".
Result: The code on the injector is not the same as the code in the ECM.
Repair: Use the electronic service tool to input the correct injector code. Refer to Troubleshooting, "Injector Code - Calibrate" for the correct procedure.
Use the electronic service tool to clear all logged diagnostic codes and then verify that the repair eliminates the fault.
