HYDRAULIC CONTROL UNIT RELAY BOX
The system relay and pump/motor relay are both
serviced together as an assembly with the relay box.
The relay box is mounted directly to the HCU.
To remove the relay box from the HCU, the HCU
requires removal from the vehicle. This is to allow
visual access of the relay box to HCU electrical con-
nection. Visual access to this connection is necessary
to be sure connection is correctly made when install-
ing the relay box on the HCU.
