Case IH 2198 – ACML: ACML wrongly configured

The Armrest Control Module (ACML) has lost its proper configuration parameters, has been programmed incorrectly, or is failing to communicate its configured state to the tractor's main controller network.

• VESTRUM CVX
• Maxxum Series (115, 135, 145, 150)
• Puma Series (150, 220)

1. 1

   Verify if the Armrest Control Module was recently replaced, as new modules require initial configuration.

2. 2

   Access the tractor's Universal Controller (U1) / display monitor (such as the H1 menu screen) to check the current calibration and configuration status of the armrest components.

1. 1

   Access Universal Controller

   Access the tractor's Universal Controller (U1) via the cab display.

2. 2

   Navigate to calibration menu

   Navigate to the H1 menu (or equivalent configuration screen) to perform the calibration procedures for the electronic modules.

3. 3

   Reconfigure ACML

   Reconfigure the ACML to match the tractor's specific installed options (e.g., EHR, PTO, advanced steering).

4. 4

   Replace and reprogram ECU

   If the ACML refuses to accept the configuration or fails to save the parameters, the physical ECU module is likely defective and must be replaced and reprogrammed.
