Case IH 15247 – MTA CCM & APH STAGE V MR: Incorrect steering valve controller configuration - Auxiliary steering device enabled - invalid flag value/invalid setpoint

This code indicates a software configuration mismatch or an invalid parameter within the steering system. Specifically, the controller is detecting that an auxiliary steering device (such as the AccuGuide auto-steer system) is enabled in the software, but the configuration flag or the setpoint value provided is invalid or does not match the physical hardware.

1. 1

   Verify ECU Identifiers using the Case IH Electronic Service Tool (EST) to check the software version and ECU identifiers for the steering valve controller.

2. 2

   Check the status of the 'Auxiliary steering device' flag in the steering valve controller configuration menu.

3. 3

   Perform a hardware crosscheck to verify if the tractor is actually equipped with an auxiliary steering device (like AccuGuide). If not, the flag should be disabled.

4. 4

   Review the steering valve setpoints to ensure no values are out of the valid range.

1. 1

   Connect diagnostic tool

   Connect the diagnostic service tool to the machine's diagnostic connection port.

2. 2

   Navigate to configuration settings

   Navigate to the MTA CCM / Steering Controller configuration settings.

3. 3

   Correct invalid flag value

   Correct the invalid flag value. If the machine has an auxiliary steering device, ensure the correct specific valve type and setpoints are selected. If it does not, disable the 'Auxiliary steering device enabled' flag.

4. 4

   Perform calibration

   Perform the steering valve calibration procedures as outlined in the Stage V MR on-board diagnostics manual.

5. 5

   Save and cycle power

   Save the configuration, clear the fault code, and cycle the tractor's key power to ensure the code does not return.
