A configuration mismatch or setup error with the joystick keypad, indicating the control module has lost communication with the multi-function joystick keypad or the keypad is not configured correctly on the CAN bus network.

• MAGNUM AFS Connect
• Case IH Magnum AFS Connect Series (Models 180, 200, 220, 240, 250, 280, 310, 340, 380)
• Case IH Steiger Series (Models 350 to 600)

1. 1

   Check for other active codes indicating a total loss of communication with the armrest (e.g., code 2818). If present, the issue is likely the main ACM power/ground or CAN bus.

2. 2

   Disassemble the armrest console and physically inspect the wiring harness connecting the joystick keypad to the ACM for disconnected plugs, backed-out pins, or chafed wires.

3. 3

   Use the Case IH Electronic Service Tool (EST) to verify the ACM software version and ensure the joystick keypad is properly configured and recognized.

1. 1

   Power down tractor

   Turn off the tractor and disconnect the battery to prevent electrical shorts while working on the sensitive armrest electronics.

2. 2

   Access the ACM and joystick

   Remove the protective covers and panels on the right-hand armrest console to expose the Armrest Control Module and the base of the multi-function handle/joystick.

3. 3

   Repair or reconnect harness

   Securely reconnect the keypad harness if unplugged. If the wiring is damaged, repair or replace the armrest wire harness.

4. 4

   Replace faulty components

   If wiring is intact but the keypad fails to communicate, replace the multi-function handle assembly. If the EST tool cannot communicate with the armrest at all, replace the ACM.

5. 5

   Recalibrate the system

   Reconnect the battery, connect the Case IH EST laptop, navigate to the Armrest Control Module settings, and perform the joystick configuration/calibration routine to clear code 2664-19.
