Case IH 519572-09 - UCM – UCM: Steering valve controller calibration fault

Indicates that the calibration process for the steering valve controller has failed, or the stored calibration data is missing, corrupted, or out of range.

1. 1

   Check for related active faults for the CAN wheel angle sensor (e.g., signal crosscheck failures, open/short circuits) or CAN communication failures between the steering valve controller and the steering wheel sensor, as these prevent successful calibration.

2. 2

   Verify UCM power and ground at pins 22 and 24. Missing power or ground will cause software operations and downloads to fail.

3. 3

   Check the software versions of the UCM and the Steering Valve Controller (SVC). Outdated software can cause calibration checksum errors.

1. 1

   Connect diagnostic tool

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

2. 2

   Navigate to module

   Navigate to the UCM / Steering Valve Controller module.

3. 3

   Update software

   If the software is outdated, flash the UCM and Steering Valve Controller (SVC) to the latest software version (e.g., SVC software version 2.02).

4. 4

   Initiate calibration

   Initiate the steering valve calibration wizard via the EST or the in-cab Pro 700/1200 display.

5. 5

   Complete calibration

   Follow the on-screen prompts to complete the calibration. Ensure the machine is on level ground and the steering system is free of physical obstructions during the process.

6. 6

   Verify repair

   Clear the fault codes and cycle the key to verify code 519572-09 does not return.
