Relay Box Replacement
GENERAL INFORMATION
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
Hydraulic Control Unit (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 connection. Visual access to this connection is necessary to be sure connection is correctly made when installing
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. Refer to Hydraulic Control Unit Removal, for the required HCU removal procedure.
