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.
