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.
REMOVE
(1) Disconnect negative (ground) cable from the
battery and isolate the cable.
(2) Remove the HCU from the vehicle. See
Hydraulic Control Unit in the Removal And Installa-
tion Section in this group of the service manual, for
the required removal procedure for the HCU.
(3) Remove the 2 screws (Fig. 25) attaching the
relay box assembly to the HCU. Remove only the 2
screws mounting the relay box to the HCU do
not remove the pump motor mounting screws
(Fig. 25).

(4) Grasp relay box with both hands. Without
twisting or rocking, pull relay box away from pump
motor housing until connector on relay box unplugs
from the pump motor terminal (Fig. 26). This is a
tight connection, relay box will require a good
amount of force to unplug it from the pump
motor.
