Case IH 15286 - AST – Steering Valve Controller (SVC) / AST: Incorrect steering valve controller configuration - configured for auxiliary steering device

This code indicates a configuration mismatch within the tractor's steering system. The software is currently configured to expect an auxiliary steering device, but the physical hardware present on the tractor (or the requested hydraulic flow crosscheck) does not match this configuration.

• MAXXUM T4E
• VESTRUM CVX
• AFS Connect Magnum Series (Models 180, 200, 220, 240, 250, 280, 310, 340, 380)
• Optum Series
• Vestrum CVX Series (Models 100, 110, 120, 130)
• Maxxum Series (CVT models)
• Puma Series
• Farmall Series (e.g., Farmall C Series)

1. 1

   Verify if the tractor is physically equipped with an auxiliary steering device

2. 2

   Access the AST control subsystem (via EST or instrument cluster H-menu) to verify the current configuration parameters of the Steering Valve Controller

3. 3

   Verify the software version and dataset of the Steering Valve Controller to ensure the Advanced Steering Configuration controller dataset matches the tractor's build

1. 1

   Enter Diagnostic Mode

   Connect the EST diagnostic tool, or enter the diagnostic mode manually by navigating the H-menus using the switches on the instrument cluster.

2. 2

   Navigate to the AST Module

   Navigate to the R1 module, menu H3, and select the AST system. Press the dimming key to accept the menu selection.

3. 3

   Correct the Configuration

   Review the configuration settings. If the tractor does not have an auxiliary steering device, change the configuration parameter to disable the auxiliary steering device setting.

4. 4

   Perform Steering Calibration

   If the configuration is correct but the fault persists, perform an AST Steering Calibration procedure.

5. 5

   Software Flash

   If calibration fails or the fault returns, re-flash the Steering Valve Controller (SVC) with the correct software dataset (e.g., dataset version 3.2, part number 51573865).

6. 6

   Hardware Replacement

   If software correction and calibration do not resolve the issue, the Steering Valve Controller unit has likely suffered an internal hardware failure and the steering valve/controller assembly must be replaced.
