Table 1
Diagnostic Trouble Codes for "Injector Data Incorrect"
J1939 Code Description Notes
630-2 Calibration Memory : Erratic, Intermittent, or Incorrect The Electronic Control Module (ECM) detects one of the following conditions.
An injector code has not been programmed for one or more of the injectors.
OR
The injector code for one or more of the injectors is invalid.
The engine may have rough running at low idle.
651-2 Engine Injector Cylinder #01 : Erratic, Intermittent, or Incorrect The ECM detects that the injector closing time is out of the specification defined by the injector code.
The warning lamp will come on.
Once the engine has been running for a period of time, the ECM will recalibrate the correct values for the injectors and the diagnostic code will be cleared.
652-2 Engine Injector Cylinder #02 : Erratic, Intermittent, or Incorrect
653-2 Engine Injector Cylinder #03 : Erratic, Intermittent, or Incorrect
654-2 Engine Injector Cylinder #04 : Erratic, Intermittent, or Incorrect
651-13 Engine Injector Cylinder #01 : Out of Calibration The ECM detects that the injector codes that have been programmed are from the wrong family of injectors.
The warning lamp will come on.
652-13 Engine Injector Cylinder #02 : Out of Calibration
653-13 Engine Injector Cylinder #03 : Out of Calibration
654-13 Engine Injector Cylinder #04 : Out of Calibration The following background information is related to this procedure:Injector codes are seven digit alphanumeric codes that are supplied with each injector. The code is printed on each 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 That the Correct Injector Codes Have Been Programmed
A. Check that the injector codes that have been programmed match the codes that are on the injectors.
Refer to Troubleshooting, "Injector Code - Calibrate".
Injector codes
Result: The injector codes are correct.
Proceed to Test Step 2.
Result: One or more of the injector codes is incorrect.
Repair: Use the electronic service tool to program the correct injector codes.
Refer to Troubleshooting, "Injector Code - Calibrate".
Proceed to Test Step 2.
2. Check for Active Diagnostic Codes
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. Use the electronic service tool to check for active diagnostic codes.
Diagnostic codes
Result: One of the following diagnostic codes is active:
651-2
652-2
653-2
654-2
Note: The ECM will learn the correct values in order to clear these diagnostic codes. Only continue with this procedure if the code has been active for at least 2 hours after the injector code was programmed.
Proceed to Test Step 3.
Result: One of the following diagnostic codes is active:
630-2
651-13
652-13
653-13
654-13
Proceed to Test Step 3.
3. Re-Flash the ECM
A. Reflash the ECM. Refer to Troubleshooting, "ECM Software - Install".
B. Ensure that all of the injector codes are programmed. Refer to Troubleshooting, "Injector Code - Calibrate".
C. Use the electronic service tool to clear all active diagnostic codes.
D. Start the engine.
E. Use the electronic service tool to check for active diagnostic codes.
