1. 1

   Power Cycle

   Completely power down the machine and disconnect the battery to force a hard reset of the ZDC module, clearing any volatile memory glitches.

2. 2

   Software Flash

   Check with a Case IH dealer to see if a software update or re-flash is available for the ZDC module, as sometimes memory addressing errors can be resolved via firmware updates.

3. 3

   Module Replacement

   If the code persists after a hard reset and software check, the internal hardware (RAM/CPU) is likely permanently damaged, requiring a replacement of the ZDC module.
