DIAGNOSIS
While the transfer case control unit (TCCU) is active it
periodically monitors its inputs and outputs. If a fault
is detected the 4WD CHECK lamp is illuminated and a
fault code is stored in the TCCU memory.
When requested, fault codes are downloaded to scan
tool through a diagnostic connector (K-line) serial com
munication.
SELF-DIAGNOSTIC TESTS
TCCU Internal Function
When the ignition is turned on the TCCU tests its read
only memory (ROM) and random access memory
(RAM). If there is a fault, the TCCU immediately resets
itself and re-tests the ROM and RAM. If the fault
persists the TCCU continues to reset and re-test until
the fault is corrected or the ignition is turned off. All
TCCU functions are inhibited until the fault is corrected.
The 4WD CHECK lamp is not illuminated if there is a
ROM or RAM fault.
If the ROM/RAM passes the electronically erasable
programmable read only memory (EEPROM) is tested.
If there is a fault the 4WD CHECK lamp is illuminated
and the TCCU continues to operate using the default
calibration data stored in ROM. Fault codes are not
stored when there is an EEPROM fault.
An EEPROM fault can only be cleared by cycling
ignition OFF-ON.
Shift Motor Assembly Test
If the TCCU detects a shift motor or position encoder
fault continuously for one second the 4WD CHECK
lamp is turned on and the appropriate fault code is
stored in memory.
1. A shift motor fault when the motor is off is defined
as follows:
Motor HI-LO circuits are shorted to ground.
Motor LO-HI circuits are shorted to ground.
Motor circuits are open.
2. A shift motor fault when the motor is energized is
defined as follows:
Motor HI-LO circuits are shorted to ground.
Motor LO-HI circuits are shorted to ground.
Motor HI-LO circuits are shorted to motor LO
HI circuits.
Motor circuits are open.
3. A position encoder fault is defined as follows:
Any position code which does not correspond
to the valid 9 codes.
A short to ground on any of the encoder lines.
4. If no shifts are in progress when a failure occurs
the TCCU will not respond to any shift commands.5. If a shift command has been received but not
acted upon when a failure occurred the TCCU
would cancel the command and not respond to
any subsequent shift commands.
6. If a shift command is in progress when an invalid
position code is confirmed it will be halted and
the TCCU will turn the motor toward the high
position. Afterwards the TCCU will not respond to
any shift commands.
7. If the shift motor or position encoder assembly
failures, other than a motor failure which occurs
when the motor is energized, recovers continuously
for one second the TCCU will function normally.
The 4WD CHECK lamp is turned off but the fault
code will remain in memory.
8. A motor failure (i.e. open or short circuit) which
occurs when the motor is energized can only be
cleared by cycling the ignition OFF-ON.
Front Speed Sensor Test
If a front speed sensor fault is detected continuously
for 0.5 second the 4WD CHECK lamp is illuminated.
The TCCU then responds as follows:
1. If the system is in high range the TCCU uses the
rear speed sensor to determine the EMC touch off
level and wheel slip control is suspended.
2. If the system is in low range, the EMC duty cycle
is set to maximum, independent of vehicle speed,
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 the front speed sensor recovers continuously for O.5
second the TCCU will function normally. The 4WD
CHECK lamp is turned off but the fault code will remain
in memory.
Rear Speed Sensor Test
If a rear speed sensor fault is detected continuously
for 0.5 second the 4WD CHECK lamp is illuminated.
The TCCU then responds as follows:
1. If the system is in high range the TCCU uses the
front speed sensor to determine the EMC touch
off level and wheel slip control is suspended.
2. If the system is in low range, the EMC duty cycle
is set to maximum independent of vehicle speed
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.
4. If the rear speed sensor recovers continuously for
0.5 second the TCCU will function normally. The
4WD CHECK lamp is turned off but the fault code
will remain in memory.

input shaft until it seats in the input shaft using
bearing remover/installer.
Press in a new bushing.

Slipped road such as snow, rainy, sand, mud etc.
Max driving force requiring condition such as
towing, rough road.
When a vehicle is driven in turning at low speed on
the paved road, a vibration and a noise may be
occurred by tight corner braking.
2WD ↔ 4WD transfer is possible below 70 km
without operating the clutch.
Manual Transmission
Transfer starts after the vehicle stops and the clutch
is applied
Automatic Transmission
Transfer starts after the vehicle stops and the shift
lever is shifted [N] position.
Notice: After the vehicle stops and the mode switch
is selected with applying the brake pedal, shifting
[N-R-N] makes the mode transfer easier.

REFRIGERANT CHARGING
Installation of Manifold Gauge
1. Close both high/low pressure hand valves of
manifold gauge before installation of gauge to the
charging valve.
2. Both high/low pressure hand valves of manifold
gauge connect the appropriate charging valve.
Tighten the hose nuts by hand.
high pressure hand valve → high pressure
charging valve
low pressure hand valve → low pressure
charging valve
Discharging Refrigerant
1. Connect the manifold gauge to the charging valve.
2. Place the free end of the center hose in a shop
towel.
3. Slowly open the high pressure hand valve and
discharge refrigerant.
Notice: If refrigerant is allowed to escape too fast,
compressor oil will be drawn out of the system.
4. Check whether the shop towel gets wet in oil and
if wet, close the hand valve.
5. After the high pressure gauge reading drops below
3.5 kg/cm
2, slowly open the low pressure valve.
6. When both high and low pressure gauges reading
drops to 0 kg/cm
2, discharging is completed.
Evacuating Refrigeration System
Notice: The unit tank must contain a sufficient amount
of R-134a refrigerant for charging. Check the amount
of refrigerant in the tank. If there is less than 3.6 kg
(8 pounds) of refrigerant, add new refrigerant to the
tank.
1. Verify that the high-side and the low-side hoses
are connected to the A/C system. Open both the
high-side and the low-side valves on the unit’s
control panel.
2. Open both the gas and the liquid valves on the
tank.
