1. 1

   Cycle the power by restarting the engine and cycling the key switch ON and OFF to reset communication messages

2. 2

   Visually inspect around the batteries and the alternator for any signs of apparent damage, loose connections, or accumulation of debris

3. 3

   Verify the integrity of the system fuses (such as F29 or F30) to ensure the module is receiving proper voltage

1. 1

   Verify the Code

   After performing the diagnostic restarts, check the CommandCenter display to see if the active Diagnostic Trouble Code (DTC) reappears.

2. 2

   Software Flash / Reprogramming

   Have an authorized John Deere dealer connect their diagnostic tool (Service ADVISOR) to attempt to overwrite the corrupted configuration memory.

3. 3

   Module Replacement

   If the internal memory has suffered a hard hardware failure and cannot accept a software flash, the Rear Chassis Module (SCC) must be physically replaced.

4. 4

   Calibration

   Whether the module is reprogrammed or replaced, the dealer must perform a system calibration to restore full functionality to the rear chassis and selective control valves.
