Case IH 15007 – Steering Controller: Split valve LVDT - short circuit

The controller detects a short circuit in the Split Valve LVDT sensor's electrical circuit, meaning the voltage signal is out of the expected range (likely shorted to ground or to another voltage source).

1. 1

   Inspect the wiring harness running from the Steering Controller to the Split Valve LVDT for chafed wires, melted insulation, or pinched lines

2. 2

   Disconnect the LVDT sensor and check the electrical connectors for water ingress, corrosion, or bent pins

3. 3

   Test the LVDT sensor with a multimeter to determine if the short circuit is internal to the sensor itself

4. 4

   Check for related steering codes (such as 15012 or 15014) that might indicate a mechanical bind

1. 1

   Power down and disconnect battery

   Power down the tractor and disconnect the battery to protect the Steering Controller.

2. 2

   Repair or replace wiring

   If the diagnostic checks reveal damaged wiring, repair or replace the affected section of the steering harness.

3. 3

   Replace Split Valve LVDT

   If the wiring is intact but the sensor is internally shorted, remove the defective Split Valve LVDT from the steering hydraulic valve block and install a new sensor.

4. 4

   Reconnect battery and clear codes

   Reconnect the battery and clear the fault codes.

5. 5

   Recalibrate steering system

   After replacing steering components or sensors, recalibrate the steering system to prevent fault code 15024 (System not calibrated).
