1. 1

   Check for accompanying Diagnostic Trouble Codes (DTCs) related to the VLC, such as VLC 000628.12 (VLC Programming) or VLC 002149.06 (VLC Circuit Current High)

2. 2

   Verify power and ground to ensure the Vehicle Load Center is receiving proper voltage, as voltage spikes or drops can interrupt the module's ability to write to its internal memory

3. 3

   Attempt to run the VLC calibration procedure to see if the parameters will overwrite successfully before assuming hardware failure

1. 1

   Connect diagnostic tool

   Connect the machine to John Deere Service ADVISOR.

2. 2

   Check software payload

   Check the current software payload on the Vehicle Load Center (VLC).

3. 3

   Reflash the Module

   Update or reflash the VLC control software to the latest version to rule out a software corruption issue.

4. 4

   Run calibration

   Run the module calibration procedure again.

5. 5

   Cycle key

   Cycle the key to prompt the module to save the parameters.

6. 6

   Check for returning fault

   If fault code 000630.31 returns, the internal EEPROM/memory of the VLC has failed and cannot retain data.

7. 7

   Replace the Module

   Remove and replace the Vehicle Load Center (VLC) / Rear Chassis Module.

8. 8

   Program and calibrate

   Use Service ADVISOR to program the End-of-Line (EOL) data and calibrate the new module.
