Precautions
EDS001KL
●
Before connecting or disconnecting the transfer control
unit harness connector, turn ignition switch “OFF” and dis-
connect battery ground cable. Battery voltage is applied to
transfer control unit even if ignition switch is turned “OFF”.
●
When connecting or disconnecting pin connectors into or
from transfer control unit, take care not to damage pin ter-
minals (bend or break).
When connecting pin connectors make sure that there are
not any bends or breaks on transfer control unit pin termi-
nals.
●
Before replacing transfer control unit, perform transfer con-
trol unit input/output signal inspection and make sure
transfer control unit functions properly. Refer to
"Transfer Control Unit Input/Output Signal Reference Val-
ues"
.
Service Notice
EDS001KM
●
After overhaul refill the transfer with new transfer fluid.
●
Check the fluid level or replace the fluid only with the vehicle parked on level ground.
●
During removal or installation, keep inside of transfer clear of dust or dirt.
●
Disassembly should be done in a clean work area.
●
Before proceeding with disassembly, thoroughly clean the transfer. It is important to prevent the internal
parts from becoming contaminated by dirt or other foreign matter.
●
Check for the correct installation status prior to removal or disassembly. If matchmarks are required, be
certain they do not interfere with the function of the parts when applied.
●
All parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection or
reassembly.
●
Check appearance of the disassembled parts for damage, deformation, and unusual wear. Replace them
with a new ones if necessary.
●
Gaskets, seals and O-rings should replaced any time the transfer is disassembled.
●
In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If
tightening sequence is specified, use it.
●
Observe the specified torque when assembling.
●
Clean and flush the parts sufficiently and blow-dry them.
●
Be careful not to damage sliding surfaces and mating surfaces.
