Case IH 2664-14 - ACM – ACM: Joystick keypad configuration

The system has detected that the joystick keypad was disconnected while powered on. This indicates a sudden loss of communication or physical disconnection between the joystick and the armrest network while the tractor's key was in the ON position.

• MAGNUM AFS Connect
• Magnum AFS Connect Series (Models 180, 200, 220, 240, 250, 280, 310, 340, 380, 400)
• Optum AFS Connect Series (e.g., Optum 270 CVX)
• Steiger AFS Connect models

1. 1

   Check for Operator Error: Determine if the armrest was recently disassembled or if the joystick was intentionally unplugged while the tractor key was turned ON. If so, the code is operating as designed.

2. 2

   Key Cycle: Turn the tractor completely off, wait for the modules to power down, and turn the key back on. If it was a temporary disconnect, the code should change from Active to Inactive.

3. 3

   Harness Inspection: Inspect the wiring harness and the electrical connector at the base of the Multi-Function Handle (joystick) and where it routes to the ACM. Look for loose connections, backed-out pins, or pinched wires inside the armrest console.

1. 1

   Power Down

   Turn off the tractor and disconnect the battery to prevent electrical spikes during repair.

2. 2

   Access the Armrest

   Carefully remove the trim panels on the AFS Connect armrest to access the base of the joystick and the ACM wiring harness.

3. 3

   Re-seat Connectors

   Disconnect the joystick keypad connector, inspect the pins for corrosion or damage, and firmly reconnect it to ensure it is fully seated and locked.

4. 4

   Repair Wiring (If Applicable)

   If any wires are chafed or pinched within the armrest pivot points, repair the wiring harness per OEM electrical standards.

5. 5

   Test and Clear

   Reconnect the battery and turn the key ON. Check the AFS Pro 1200 display to see if code 2664-14 has moved to an inactive state. Clear the inactive codes.

6. 6

   Replace Component

   If the wiring is perfectly intact, the connector is secure, and the code remains active, the internal circuitry of the joystick keypad has likely failed and the Multi-Function Handle must be replaced.
