Case IH 55015: Rear PVE - status error signal from valve

55015 is not a specific fault code, but rather the section/group index code for the Engine control system. The associated 'error signal from valve' indicates the PVE module's internal function monitor has detected a fault (such as a mismatch between commanded signal and actual spool position, or incorrect power supply) and cut off the signal output.

1. 1

   Verify that the feed power to the valve is correct. An incorrect power supply will trigger an error signal.

2. 2

   Verify that the analog/PWM signal to the valve is correct and within the permissible amplitude and pulse/pause ratio.

3. 3

   Check the wiring harness connecting the controller to the PVE module for damages, shorts, or poor quality connections.

4. 4

   Disconnect the supply voltage to the EHSC (Electronic Hydraulic Speed Control) or PVE module to reset the function monitor, then reconnect to see if the fault clears.

1. 1

   Disconnect valve

   Disconnect the affected rear remote valve (Danfoss module).

2. 2

   Restart system

   Bring the control lever back to the neutral position and restart the system.

3. 3

   Replace PVE module

   If the error code remains and the wiring is confirmed good, the PVE module (magnetic coils/electronic circuit) is defective and must be changed.
