5D1-4 TRANSFER CASE (PART TIME 4408)
SELF-DIAGNOSIS
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 the engine room 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.
lTCCU
lShift motor
lMagnetic synchronizer clutch
lSpeed sensor
lHub solenoid
lSelector switch
lMotor position sensor
3. Transfer case system is malfunctioning when:
l4H ,4L indicator lights are remain on after 0.6 second
when turning the ignition switch ‘ON’
l4H,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.

TRANSFER CASE (PART TIME 4408) 5D1-5
Defective Code Reading
1. Position the ignition switch to ‘OFF’
2. Using a service connector, connect the No.2 pin ( lgnition )
and No.6 pin (TCCU) of the diagnosis socket in the engine
room.
3. Position the ignition switch to 'ON'.
4. Read the flashing ‘4WD CHECK’ indicator light and identify
the malfunctioning part.
How to Eliminate the Falut Code
1. Position the ignition switch to ‘OFF’
2. Using a service connector, connect the No.2 pin (GND) and
No.6 pin (TCCU) of the diagnosis socket in the engine room.
3. Position the ignition switch to ‘ON’ over 5 seconds.
4. Do defective code reading and make sure that all defective
codes are eliminated.

Coding Method
1. Check and record engine type, axle ratio and tire size.
2. Ignition “OFF”.
3. Connect SCANNER with diagnosis connector in engine
room.
4. Ignition “ON”.
5. Read the current memorized specification in TOD control
unit.
6. Compare memorized specification with the checked record.
If not matched, perform a coding.
7. Read again memorized coding specification in TOD control
unit for confirmation of coding.
8. Check coding specification whether it matches with vehicle
or not. If not, perform a coding again.
