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.

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.
The PVED-CL has a LED mounted at the connector side for low level diagnostic.
PVED-CL Status
No battery power is supplied to the PVED-CL
PVED-CL is in fault state. More information is available in DM1 CAN message.
PVED-CL is operational but no device has been selected.
Once a steering device is activated, the LED changes to green.
PVED-CL is operational
PVED-CL is in reduced state
PVED-CL is operating in calibration mode
A critical PVED-CL specific fault has happened – PVED-CL is in fail silent state (silent ~ disconnected from
the CAN bus)
