Power Supply Voltage
SPN 627 indicates that the battery voltage supply is either below 9V or has exceeded 32V.
Sensor Supply Voltage
SPN 1079 indicated that the regulated 5V supply for external sensors is out of range. This could be due to
a short-circuit, overload or an internal PVED-CL hardware fault
Loss of Main Spool Control or Spool Position Plausibility Check Failure
SPN 614 indicates that the main valve spool is out of control. This may be caused by an incorrect sensor
mapping i.e. if a SASA sensor is not mapped as present and the steering wheel is activated
simultaneously with e.g. a joystick. Secondly it may indicate that the spool position signal is out of range.
Subsequently the fault my also be traced to a PVED-CL hardware error.

13053
Main valve spool is out of control.
13054
Main valve spool position signal is out of range.
Internal PVED-CL Error
SPN 615 indicates that a critical PVED-CL fault has happened. The user must look up the EHPS error
buffer to retrieve the EHPS error code and apply the table with PVED-CL error codes to locate the error
source. The user shall locate the last entered error entry which is either the last error code before the ‘No
error’ code or the error code at the last error entry. If the error buffer is filled up, new error codes will
overwrite the error code in the last error entry.
LED Diagnostic
The PVED-CL has a LED mounted at the connector side for low level diagnostic.
LED color
PVED-CL Operation
Status
PVED-CL Status
Black / Off
Not available
No battery power is supplied to the PVED-CL
Orange
Fault
PVED-CL is in fault state. More information is available in DM1 CAN message.
Operational
PVED-CL is operational but no device has been selected.
Once a steering device is activated, the LED changes to green.
Green
Operational
PVED-CL is operational
Reduced
PVED-CL is in reduced state
Calibration
PVED-CL is operating in calibration mode
Red
Not available
A critical PVED-CL specific fault has happened – PVED-CL is in fail silent state (silent ~ disconnected from
the CAN bus)
