CLAAS Id78A6h / 78A6h – EXT (A62) - External Function Module: The CSM sequence is interrupted. The CSM sequence is interrupted after pressing one of the external commands

Fault code Id78A6h indicates an operational interruption rather than a hardware failure. It is logged when an active automated sequence (CLAAS Sequence Management) is canceled because the operator manually pressed an external command button (such as a hydraulic or linkage control on the CMOTION joystick or fenders) while the sequence was running.

1. 1

   Confirm with the operator if they manually pressed an external command button (e.g., spool valve, linkage, or PTO switch) while a headland sequence was actively playing

2. 2

   If the operator did not press a button, check the external command switches (such as fender buttons for PTO/linkage) and the CMOTION joystick buttons for sticking, dirt ingress, or short circuits that might be sending a false interrupt signal

3. 3

   Verify the operation of the S177 'CLAAS Sequence Management' switch on the right-hand console

1. 1

   Clear the Code

   Acknowledge and clear the code from the CEBIS or CIS+ display.

2. 2

   Operator Instruction

   Instruct the operator to let the CSM sequence finish its recorded steps before manually intervening with external hydraulic or linkage controls.

3. 3

   Restart Sequence

   Reactivate the CSM sequence using the F buttons or CMOTION joystick to ensure it completes without interruption.

4. 4

   Harness/Switch Repair

   If the sequence continues to interrupt without operator input, use a multimeter to test the continuity of the external command switches and the S177 CSM switch. Clean or replace any sticking switches.
