Precaution for Transfer Assembly and Transfer Control Unit Replacement

INFOID:0000000007357557

When replacing transfer assembly or transfer control unit, check the 4WD shift indicator pattern and adjust-

ment of the position between transfer assembly and transfer control unit if necessary.

CHECK 4WD SHIFT INDICATOR PATTERN

1. Set 4WD shift switch to “2WD”, “4H”, “4LO”, “4H” and “2WD” in order. Stay at each switch position for at

least 2 seconds.

2. Confirm 4WD shift indicator lamp and 4LO indicator lamp are changed properly as follows.

• If OK, the position between transfer assembly and transfer control unit is correct.

• If NG, the position is different between transfer assembly and transfer control unit.

Adjust the position between transfer assembly and transfer control unit. Refer to pattern table below.

Precaution

INFOID:0000000007357558

•

Before connecting or disconnecting the transfer control unit

harness connector, turn ignition switch “OFF” and disconnect

the battery cables. Battery voltage is applied to transfer con-

trol 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 termi-

nals (bend or break).

When connecting pin connectors make sure that there are not

any bends or breaks on transfer control unit pin terminals.

•

Before replacing transfer control unit, perform transfer con-

trol unit input/output signal inspection and make sure transfer

control unit functions properly. Refer to

DLN-238, "Reference

Value"

Service Notice

INFOID:0000000007357559

• 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 cer-

tain 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 tight-

ening 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.
