Case IH 2675-02 - ACM – ACM: Joystick X-Axis Neutral Position Status

The system is detecting an invalid signal or a circuit fault regarding the neutral position of the joystick's left/right (X-axis) movement. The "02" Failure Mode Identifier (FMI) signifies an "Error Indicator" (erratic, intermittent, or incorrect data).

• MAGNUM AFS Connect
• Case IH Magnum AFS Connect (Models 180, 200, 220, 240, 250, 280, 310, 340, 380)
• Case IH Steiger / Quadtrac AFS Connect
• Case IH Optum Series
• Case IH Maxxum Series (with MultiControl Armrest)

1. 1

   Check the Multi-Function Handle (MFH) / joystick for physical damage or debris that might prevent the joystick from returning to its true neutral position on the X-axis.

2. 2

   Inspect the wiring harness and connectors between the joystick and the Armrest Control Module (ACM) for bent pins, corrosion, or chafed wires.

3. 3

   Verify that the joystick is receiving the correct 5V reference voltage and has a solid ground connection.

4. 4

   Connect the Case IH EST diagnostic tool to the CAN1/ISOBUS diagnostic port to monitor the live data of the joystick X-axis position status. Check if the status changes from '0x00: Not in Neutral Position' to '0x01: In neutral Position' when moving the joystick.

5. 5

   Attempt to recalibrate the joystick and Selective Control Valves (SCVs) through the AFS Pro 1200 or Pro 700 display monitor.

1. 1

   Power down the tractor and disconnect the battery

   to prevent electrical shorts.

2. 2

   Remove the armrest cover/bezel

   to access the internal components of the MultiControl Armrest.

3. 3

   Locate the joystick / Multi-Function Handle assembly and disconnect its electrical harness connector.

4. 4

   Remove the mounting screws securing the joystick to the armrest console.

5. 5

   Install the replacement joystick and secure it with the mounting hardware.

6. 6

   Reconnect the electrical harness.

7. 7

   Reinstall the armrest bezel and covers.

8. 8

   Reconnect the battery and power on the tractor.

9. 9

   Navigate to the tractor's display monitor and perform the mandatory SCV/Joystick calibration procedure

   so the ACM can learn the new joystick's neutral, minimum, and maximum X/Y axis values.
