The EHi steering valve assembly includes the PVED−
CLS controller to operate the EHi steering valve. The
PVED−CLS controller has steering specific functions
and dedicated safety functions which are programed
specifically for the Multi Pro 5800 through the controller
firmware. The PVED−CLS includes two separate con-
trollers (Main and Safety), creating a fail−safe redun-
dancy feature which constantly cross−checks system
data. The Main and Safety controllers inside the PVED−
CLS are connected to the machine CAN bus via two
separate sets of CAN bus connections. Refer to the wire
harness drawings and diagrams in Appendix A in this
manual for additional information.
Communication (firmware uploads and calibration) with
the PVED−CLS controller is accomplished using a per-
sonal computer (PC) running Danfoss PLUS+1R Ser-
vice Tool software and the vehicle’s CAN network.
Contact an Authorized Toro Distributor for assistance.
Because of the solid state circuitry built into the PVED−
CLS controller, there is no method to test the controller
directly. The controller may be damaged if an attempt is
made to test it with an electrical test device (e.g. digital
multimeter or test light). Only the Tri−colored LED on the
PVED−CLS controller and any “AUTOSTEER” fault
codes that appear on the InfoCenter display should be
used to troubleshoot controller operation issues
(Fig. 59). Refer to AutoSteer Faults in the Trou-
bleshooting section in this Chapter.
Only the seals and particle filter located between the
PVED−CLS controller and the EHi steering valve body
can be serviced. The PVED−CLS controller is not ser-
viceable separately. The entire EHi steering valve and
PVED−CLS controller must be replaced as an assem-
bly. Refer to Electrohydraulic In−line (EHi) Steering
Valve (Optional AutoSteer Kit) in Chapter 5 − Hydraulic
System in this manual for additional information.
