Case IH 18373: CAN Message Rolling Counter Failure

A rolling counter failure is a CAN bus communication error indicating that the receiving module is seeing erratic, intermittent, or incorrect data. This is typically caused by frame loss due to high CAN bus load, message bursts during startup, or an intermittent physical connection in the CAN bus wiring. The naming convention suggests it relates to a user input device such as a joystick or armrest controller.

1. 1

   Inspect the wiring harness and connectors between the user interface controls (joysticks/pedals) and the main vehicle controller for loose pins, corrosion, or chafing.

2. 2

   Check if the error occurs only during startup or when multiple commands are issued simultaneously, which can indicate a software issue or bus overload.

3. 3

   Clear the DTC using a diagnostic scanning tool, cycle the ignition switch, and wait to see if the code returns.
