PRECAUTIONS
Service NoticeEDS001V7
After overhaul refill the transfer with new transfer oil.
Check the oil level or replace the oil only with the vehicle parked on level ground.
During removal or installation, keep inside of transfer clear of dust or dirt.
Replace all tires at the same time. Always use tires of the proper size and the same brand and pattern.
Fitting improper size and unusual wear tires applies excessive force to vehicle mechanism and can cause
longitudinal vibration.
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 matching marks 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, O-rings and lock nuts should be replaced any time when 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.
Use lint-free cloth or towels for wiping parts clean. Common shop rags can leave fibers that could interfere
with the operation of the transfer.

When reading wiring diagrams, refer to the following:
GI-14, "How to Read Wiring Diagrams".
PG-2, "POWER SUPPLY ROUTING".
When performing trouble diagnosis, refer to the following:

DRAINING
CAUTION:
When draining oil, protect exhaust tube with cover.
1. Run the vehicle to warm up the transfer body sufficiently.
2. Stop engine, and remove drain plug to drain the transfer oil.
3. Apply recommended sealant to drain plug. Install drain plug on
transfer and tighten to the specified torque. Refer to TF-59,
"COMPONENTS" .
FILLING
1. Remove filler plug and add gear oil until oil level reaches the
specified limit near filler plug mounting hole.
CAUTION:
Carefully fill the oil. (Fill up for approx. 3 minutes)
2. Leave the vehicle for 3 minutes, and check the oil level again.
3. Apply recommended sealant to filler plug. Install filler plug on
transfer and tighten to the specified torque. Refer to TF-59, "
COMPONENTS" .
InspectionEDS001W3
OIL LEAKAGE AND OIL LEVEL
1. Check oil level from filler plug mounting hole as shown in the fig-

CAUTION:
Do not start engine while checking oil level.
2. Before installing filler plug, apply recommended sealant. Install
filler plug on transfer and tighten to the specified torque. Refer to

ALL MODE 4X4 SYSTEM
4WD MODE SWITCH
AUTO Mode
Electronic control allows optimal distribution of torque to front/rear wheels to match road conditions.
4WD mode makes possible stable driving, with no wheel spin, on snowy roads or other slippery surfaces.
On roads which do not require 4WD, AUTO mode contributes to improved fuel economy by driving in con-
ditions close to front-wheel drive.
Sensor inputs determine the vehicle's turning condition, and tight cornering/braking are controlled by dis-
tributing optimum torque to rear wheels.
LOCK Mode
Front/rear wheel torque distribution is fixed, ensuring stable driving when climbing slopes.
Vehicle will switch automatically to AUTO mode if vehicle speed increases. If vehicle speed then
decreases, the vehicle automatically returns to direct 4-wheel driving conditions.
LOCK mode will change to AUTO mode automatically, when the vehicle speed exceeds approx. 30 km/h
(19 MPH). The LOCK indicator light keeps illuminating.
NOTE:
If there is a significant difference in pressure or wear between tires, full vehicle performance is not available.
LOCK mode may be prohibited, or speeds at which LOCK mode is enabled may be restricted detecting tire
conditions.
2WD Mode
Vehicle is in front-wheel drive.
NOTE:
If front wheels are slipping in 2WD mode, do not switch to AUTO or LOCK. This can cause difficulties for
the system.
Even if the 4WD mode switch is in 2WD mode, the 4WD control unit occasionally automatically change to
AUTO mode depending on the driving condition (For example; Depressing the acceleration firmly). This is
not malfunction. However, 4WD indicator lamp dose not illuminate.
4WD INDICATOR LAMP AND LOCK INDICATOR LAMP
The following is the indications of indicator lamp.
4WD WARNING LAMP
Turns ON when there is a malfunction in 4WD system. It indicates that the vehicle is in fail-safe mode and
change to front-wheel drive or shifting driving force-4WD (Rear-wheels still have some driving torque).
Also turns ON when ignition switch is turned ON, for purpose of lamp check. Turns OFF approximately for 1
seconds after the engine starts if system is normal.

Fail-Safe FunctionEDS001VE
If any malfunction occurs in 4WD electrical system, and control unit detects the malfunction, 4WD warning
lamp on combination meter turns ON to indicate system malfunction.
When 4WD warning lamp is ON, vehicle changes to front-wheel drive or shifting driving force-4WD (Rear-
wheels still have some driving torque).
How to Perform Trouble DiagnosisEDS001VF
BASIC CONCEPT
To perform trouble diagnosis, it is the most important to have understanding about vehicle systems (con-
trol and mechanism) thoroughly.
It is also important to clarify customer complaints before inspec-
tion.
First of all, reproduce symptoms, and understand them fully.
Ask customer about his/her complaints carefully. In some cases,
it will be necessary to check symptoms by driving vehicle with
customer.
CAUTION:
Customers are not professional. It is dangerous to make an
easy guess like "maybe the customer means that...," or
"maybe the customer mentions this symptom".
It is essential to check symptoms right from the beginning in
order to repair malfunctions completely.
For intermittent malfunctions, reproduce symptoms based on
interview with customer and past examples. Do not perform
inspection on ad hoc basis. Most intermittent malfunctions are
caused by poor contacts. In this case, it will be effective to shake
suspected harness or connector by hand. When repairing with-
out any symptom diagnosis, you cannot judge if malfunctions
have actually been eliminated.
After completing diagnosis, always erase diagnostic memory.
Refer to TF-33, "
How to Erase Self-diagnostic Results" .
For intermittent malfunctions, move harness or harness connec-
tor by hand. Then check for poor contact or reproduced open circuit.
