1. 1

   Check battery voltage (low battery voltage under 9.8 V can cause the UCM's Non-Volatile Memory to corrupt and revert to default values)

2. 2

   Inspect power connections for poor power supply or loose grounds at the UCM harness

3. 3

   Review recent service history to determine if the UCM NVM was inadvertently cleared during a software update or if physical systems were added/removed without updating the software

1. 1

   Connect diagnostic tool

   Connect the Case IH Electronic Service Tool (EST) to the machine's diagnostic port.

2. 2

   Reinstall software

   If the module's memory is corrupted, reinstall the UCM software using the EST.

3. 3

   Navigate to configuration

   Navigate to the UCM/VCM configuration screen. Note: Do not change configuration values from the standard 'Implement' card on the Pro 1200 display, as they will override the correct values; use the EST or dedicated setup wizard.

4. 4

   Reconfigure module

   Reconfigure the module to match the physical systems installed on the tractor (for example, changing a setting like line 21 for a grid heater to 'Installed').

5. 5

   Save settings

   Save the new settings in the EST.

6. 6

   Restart tractor

   Restart the tractor (cycle the key power).

7. 7

   Check faults

   Check the 'Faults' screen on the display. If the configuration was successful, the active fault code will become inactive (color-coded green) and will clear after the key cycle.

8. 8

   Test operation

   Test the operation of the newly configured systems to verify the repair.
