Case IH 15201 – Advanced Steering Controller: Steering valve controller battery voltage too low.

The system triggers this code when the voltage on the electronic steering valve input specifically at connector C361, pin 8 drops to less than 9 Volts.

1. 1

   Verify overall battery health and alternator charging output to ensure the machine is producing adequate voltage globally.

2. 2

   Disconnect connector C361 at the electronic steering valve controller and use a multimeter to measure the voltage at pin 8 with the key ON (must read 9 V or higher).

3. 3

   Visually inspect the wiring harness leading to the steering valve controller for chafing, pinch points, or melted insulation.

4. 4

   Inspect connector C361 for water intrusion, pushed-out pins, or corrosion, and check the specific fuses and relays that supply power to the steering valve circuit.

1. 1

   Resolve Power Supply Issues

   If the voltage at C361 pin 8 is below 9 V, trace the circuit back to the power distribution box. Locate and repair any open circuits, high-resistance areas, or shorts to ground.

2. 2

   Repair Wiring/Connectors

   Clean any corrosion from connector C361 using electrical contact cleaner. If pin 8 is damaged or loose, replace the pin terminal or splice in a wiring harness repair pigtail.

3. 3

   Replace Fuses/Relays

   If a blown fuse or faulty relay is found during the diagnostic phase, replace it and re-test the voltage at the connector.

4. 4

   Module Replacement

   If the wiring, fuses, and power supply are all verified to be delivering 12V+ to the connector, but the code remains active when plugged in, the Steering Valve Controller (SVC) likely has an internal short or failure and must be replaced.

5. 5

   Calibration

   If the SVC or electronic steering valve is replaced, the new module will require software flashing and steering calibration via the Case IH Electronic Service Tool (EST).
