Description

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.
TCCU
Shift motor
Magnetic synchronizer clutch
Speed sensor
Hub solenoid
Selector switch
Motor position sensor
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 malfunctioningparts 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. NoticeBefore replacing the malfunction parts with defective code, check the wires and connectors for proper condition.

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.
