Case IH 518413-14 - ACM – ACM: Incorrect navigation encoder keypad configuration

The FMI 14 identifier indicates a "Special Instruction" or configuration mismatch. This code triggers when the system detects that the navigation encoder keypad (the rotary dial and surrounding shortcut buttons used to navigate the display screen) is not configured correctly within the system's software, or there is a mismatch between the installed hardware version and the software configuration.

1. 1

   Check for related codes (e.g., 518413-09, 518413-19, or 518413-03) that might indicate a hardware failure rather than a configuration issue

2. 2

   Verify software compatibility to ensure that the Armrest Control Module (ACM) firmware is up to date and compatible with the AFS Pro 1200 display software

3. 3

   Inspect the wiring harness and connectors between the navigation encoder keypad and the ACM for loose pins, corrosion, or damage that might be causing intermittent communication drops

4. 4

   Connect the Electronic Service Tool (EST) and verify the current configuration status of the armrest and keypad modules

1. 1

   Connect Diagnostic Tool

   Connect the CNH Electronic Service Tool (EST) to the machine's diagnostic port.

2. 2

   Reconfigure the Module

   Navigate to the ACM (Armrest Control Module) programming and configuration menu. Run the configuration routine for the armrest keypad/navigation encoder to ensure the software correctly identifies the installed hardware.

3. 3

   Flash/Update Firmware

   If the configuration routine fails, re-flash the ACM with the latest software payload from the CNH eTIM portal.

4. 4

   Hardware Replacement

   If the module refuses to accept the configuration or drops offline repeatedly, the internal circuitry of the navigation encoder keypad or the ACM itself may be faulty. Replace the defective keypad or ACM, then repeat the EST configuration process.
