New Holland ARMRE 9012 – Armrest Controller (ARM / ARMRE): Controller Memory Error - Loss of Aux Remote Lever Calibrations

The controller has lost the saved calibration data for the auxiliary remote hydraulic levers from its non-volatile memory. This can be caused by a temporary voltage drop, a poor ground connection, or a physical defect within the controller's internal memory chip preventing it from retaining data.

1. 1

   Check battery and charging voltage to ensure it is not dropping too low during engine cranking, which can cause memory loss.

2. 2

   Inspect connector C137 and verify the Armrest Controller has a clean, secure connection to the battery and is properly grounded.

3. 3

   Power cycle the tractor completely (shut down, wait 30 seconds, restart) to see if the code is intermittent or hard-set.

1. 1

   Access display monitor

   Turn the key switch to the ON position and access the tractor's display monitor (e.g., IntelliView or Pro 700).

2. 2

   Navigate to Calibration Menu

   Navigate to the Calibration Menu for the Armrest Controller.

3. 3

   Select AUX calibration

   Select the AUX (Auxiliary Remote Levers) calibration procedure.

4. 4

   Stroke auxiliary remote levers

   Follow the on-screen prompts to fully stroke the auxiliary remote levers through their full range of motion (extend, retract, float) so the controller can relearn the potentiometer voltage values.

5. 5

   Save and cycle key

   Save the calibration and cycle the key switch (turn off, wait, turn back on).

6. 6

   Check for fault code

   Check if fault code ARM 9012 returns.

7. 7

   Evaluate and replace controller if necessary

   If the calibration is successful and the code stays away, the issue was a temporary memory glitch. If the fault code appears again immediately or after a short period of use, the Armrest Controller's memory is defective. The Armrest Controller must be replaced. (Note: A new controller will require a dealer to use the CNH Electronic Service Tool (EST) to download the machine-specific software and perform a full calibration of all armrest functions).
