1. 1

   Verify the connections between the multifunction handle and the Armrest Control Module (EHR Control Unit).

2. 2

   Check the current software version of the ACML. Updating to a revised ACML software version with relaxed error code parameters (e.g., increasing error detection time from 50 ms to 500 ms) can resolve false error states.

3. 3

   Use the official Case IH Electronic Service Tool (EST) to read the live data of the joystick buttons if the root cause cannot be found.

1. 1

   Replace components

   Replace the faulty valve controls or the multifunction handle itself if a specific button's internal circuit has failed.
