Table 1
Diagnostic Trouble Codes
J1939 Code	Description	Comments
630-2	Calibration Memory : Erratic, Intermittent, or Incorrect	At least one of the following conditions exists: One or more of the configuration parameters are not programmed. The effect on the engine depends on the parameter. The personality module code of the flash file in the ECM is different from the personality module code of the original flash file. Engine speed is limited to low idle. All of the injector trim files are not loaded into the ECM. Engine performance and emissions are affected. Several of the above conditions can exist at the same time. The conditions that exist are displayed beneath the code. The 630-2 diagnostic code will disappear when all of the conditions have been resolved.
631-11	Calibration Module : Other Failure Mode	The flash file in the ECM is from the wrong engine family. The engine will not start.
Follow the troubleshooting procedure in order to identify the root cause of the problem.

Test Step 1. Correct the Condition

Determine the diagnostic code that is active.

Expected Result:

A 630-2 code or 631-11 code is active.

Results:

A 630-2 code is active -

Repair: Perform the following procedure:

If a programmable parameter is displayed, program that parameter with the correct value. Table 2 lists the parameters that can cause the code.

Programmable Parameter	Group of Parameters That Contains the Parameter
"Personality Module Code"	"System Settings"
"Air Inlet Shutoff Installation Status"
"FLS"
"FTS"
"Vehicle Voltage Selection"
"Engine Precooler Installation Status"
"Engine Brake System Installation Status"

If "Injector Code" is displayed, load the missing injector trim file into the ECM. Refer to Troubleshooting, "Injector Trim File - Install".

STOP

A 631-11 code is active -
Repair: Obtain the engine serial number. Use SIS to determine the latest available flash file for the engine. Verify that the latest available flash file is loaded into the ECM.
