Case IH 15294 – Steering Valve Controller (SVC): Incorrect steering valve controller configuration - CAN wheel angle sensor device enabled

Configuration mismatch, EEPROM data error, or a Cyclic Redundancy Check (CRC) failure regarding the calibration data of the CAN-based Wheel Angle Sensor (WAS) communicating with the steering valve.

• Steiger T4B
• Case IH Farmall series
• Case IH Magnum series
• Case IH Steiger
• Case IH Vestrum CVX Series

1. 1

   Verify CAN Communication by checking the Wheel Angle Sensor (WAS) counts (left, center, right) via the tractor's diagnostic display to ensure the sensor is actively reading

2. 2

   Verify that the Steering Valve Controller (SVC) software and the Advanced Steering Configuration controller datasets are up to date

3. 3

   Ensure the hydraulic oil temperature is above 5 °C (41 °F) before attempting any steering valve or sensor calibrations

1. 1

   Apply the park brake and ensure the hydraulic oil is up to operating temperature.

2. 2

   Access the calibration menu.

   On some models, this is done by pressing and holding the Autoguidance system switch while switching the ignition on and starting the tractor.

3. 3

   Capture the Right ("RGHt"), Left ("LEFt"), and Neutral ("ntrL") positions in a specific sequence.

4. 4

   Drive the tractor forward slowly at 2–6 km/h (1–4 mph).

5. 5

   Turn the steering wheel all the way to the left-hand steering lock.

   Press the corresponding button on the display to set the left-hand WAS value.

6. 6

   Turn the steering wheel all the way to the right-hand steering lock and set the right-hand WAS value.

7. 7

   Return the steering wheel to the exact straight-ahead (neutral) position and save the setting.

8. 8

   Verify the calibration voltage information shown on the cluster.

   If the display reads "Calibration OK (PASS)", the configuration has been successfully rewritten.

9. 9

   If the calibration fails repeatedly due to a CRC error or EEPROM failure, the Steering Valve Controller or the CAN Wheel Angle Sensor must be replaced and reprogrammed by a dealer.
