BLEEDING OF CLUTCH SYSTEM
Bleeding procedure
Notice: Keep the fluid level over ‘MAX’ in reservoir
during bleeding operation.
Do not let fluid contact a painted surface.
1. Remove the air bolt cap of the release cylinder.
Connect a vinyl tube to the bolt.
2. Insert the other end of the tube in a vacant
container.
3. Slowly depress the clutch pedal several times.
4. With clutch pedal fully depressed, open the air
bolt and release air rind fluid in the fluid line,
5. Repeat this procedure until there are no more air
bubbles in the fluid flows.

SECTION 5D1
TRANSFER CASE (TOD)
CAUTION: Disconnect the negative battery cable before removing or installing any electrical unit or when a
tool or equipment could easily come in contact with exposed electrical terminals. Disconnecting this cable
will help prevent personal injury and damage to the vehicle. The ignition must also be in LOCK unless
other-wise noted.

Both Speed Sensor Faulty
If both the front and rear speed sensors are faulty con
tinuously for 0.5 seconds the 4WD CHECK lamp is
illuminated. The TCCU then responds as follows:
1. If the system is in high range the TCCU sets the
EMC touch off level based on a vehicle speed of
0 and wheel slip control is suspended.
2. If the system is in low range, the EMC duty cycle
is set to maximum until the system is shifted out
of low range.
3. All electric shift activity is halted until the Ignition
is cycled. If a shift is in progress it will be
completed.
If both speed sensors recover continuously for 0.5 sec-
ond the TCCU will function normally. The 4WD CHECK
lamp is turned off but the fault code will remain in
memory.
Electro-Magnetic Clutch Test
The electromagnetic clutch (EMC) is tested for open
circuit or short circuit to ground. If a fault is detected
continuously for 0.8 second the 4WD CHECK lamp is
turned on and all TODTM activity is halted.
If the EMC recovers continuously for 0.8 second the
TCCU will function normally. The 4WD CHECK lamp is
turned off but the fault code will remain in memory.
DIAGNOSTIC TROUBLE CODES
(DTCS)
When a fault is detected a diagnostic trouble code
(DTC) is stored in the TCCU and illuminates the 4WD
CHECK indicator. This DTC will remain in memory until
the TCCU is instructed to erase DTCs by scan tool.
Notice: DTCs can not be erased by disconnecting of
power supply to the TCCU.
Diagnostic Trouble Codes Table
CLEARING DIAGNOSTIC
TROUBLE CODES
When diagnose by scan tool, it is required that you
make adequate service on defects against all fault
codes. And then you should delete the memorized fault
codes in transfer case control unit (TCCU) using scan
tool as follows;
1. Connect a scan tool with dada link connector
(DLC).
2. Select TROUBLE CODE CLEAR in scan tool.
3. In TROUBLE CODE CLEAR screen, press ENTER
key to erase the fault code.

2. Prepare a vessel to drain transfer case oil.
3. Remove the planner damper, if equipped.
4. Remove the drain plug and filler plug, and drain
the oil completely.
5. Install and tighten the drain plug.
Installation Notice
6. Replenish recommended transfer case oil to speci-
fied oil level through the filler plughole.

17. Remove the front propeller shaft speed sensor
tooth wheel.
18. Remove the chain, driven sprocket and drive
sprocket as an assembly.
19. Remove thrust washer from output shaft.
25. With expanding the tangs of the snap ring under
the planetary carrier assembly using SST snap ring
plier support the input shaft against a bench, push
the case down and slide the input shaft bearing.
Remove the input shaft and planetary carrier.
26. Remove and discard the input shaft oil seal as re
quired.
27. Remove the internal snap ring from the planetary
carrier and separate the planetary carrier from the
input shaft. 22. Remove the helical cam and shift rail as an assem-
bly by gently pulling out the shift rail. Check the
helical cam for damages and replace it if required.
23. Remove the high-low shift fork and high-low collar
as an assembly.
24. Remove the shift shaft. 20. Remove the magnet from the slot in the front of
the case bottom.
21. Remove the rear output shaft and oil pump as an
as-sembly.
Notice: If there is removal resistance, do not
pound or use force to disassemble the pump. Do

SELF-DIAGNOSIS TEST
System Description
1. TCCU detects transfer case system malfunctions
and indicates malfunctioning part(s) through
flashing 4H, 4L indicator lights.
Using a service connector, connect it to the
diagnosis box in under instrument pannel and read
the flashing of the “4WD CHECK” indicator light.
The flashing indicator light will show you defective
code(s).
2. Identify 7 defective codes after reading the
flashing indicator light.
TCCU
Shift motor
Magnetic synchronizer clutch
Speed sensor
Hub solenoid
Selector switch
Motor position sensor
KAA5D110
3. Transfer case system is malfunctioning when:
4H, 4L indicator lights are remain on after 0.6
second when turning the ignition switch ON.
4H, 4L indicator lights are continuously come
on during driving.
4. If only 1 part is malfunctioning, 4WD CHECK
indicator light will display defective code 3 times
continuously.
5. If more then 2 part is malfunctioning, the first
malfunctioning part will be displayed 3 times and
following malfunctioning parts will be displayed .
6. To read defective code, connect the service
connector and turn the ignition switch ‘ON’.
7. After repairing, eliminate the defective code stored
in the TCCU.
Notice: Before replacing the malfunction parts with
defective code, check the wires and connectors
for proper condition.
