32. Install shift shaft oil seal if it is not installed.
33. Using pliers equipped with soft jaws, rotate the triangular
shaft so it is aligned with the triangular slot in the transfer
case shift motor. If triangular shaft will not rotate, rotate
the rear output shaft.
34. Slightly loosen the two nuts that attach the slotted support
bracket to the end of the motor house.
35. Apply Black Non-Acid Cure Silicone Rubber or equivalent
to motor housing base and install on transfer case.
36. Install the transfer case shift motor and three bolts along
with speed sensor wire harness bracket and tighten.
Notice
The wire harness must be routed as shown to provide
clearance and to prevent the wire harness from grounding
the damper.
37. Holding the slotted support bracket tight against the motor
housing end, secure the bracket to the transfer case,
tightening the bolt with lockwasher to 8-11 Nm (72-96 lb-
in).
38. Retighten the two nuts that attach the slotted support
bracket to the end of the motor.
39. Install the clutch coil wire terminal and sensor wires.

FUNCTION DESCRIPTION
Air Bag Control Unit (AC4)
Air bag control unit (AC4) is installed on the center portion of
the front floor tunnel.
It is a central control unit that control all functions and determines
whether deploy the air bag or not with the collision signal from
the built-in accelerometer sensor and has function of diagnosing
system defects.
Internal air bag control unit is consisted as follows;
lMicroprocessor
lASICs (Upper side ASIC & lower side ASIC)
lAccelerometer sensor
lArming sensor
lSystem energy backup condenser
lSquib energy backup condenser

DIAGNOSIS
DESCRIPTION
Air bag control unit continuously controls system function as follows during ignition ON or driving.
- Recognition of collision
- Internal diagnosis
- External diagnosis
If recognize or detect defects, warning lamp will turn on. If there is danger of improper deployment, the system will
enter overall shutdown status and the air bag will not inflate.
Air bag control unit will store detected internal and external defects in the EEPROM.
System Control
Battery Voltage Check
Battery voltage will be monitored continuously. If voltage is out of normal operating range, all system diagnosis will
stop and warning lamp turn on.
Battery Voltage (V)
< 8.7
9 - 16
> 16.3
Function
System diagnosis stops and warning lamp turns on
Normal operation range
System diagnosis stops and warning lamp turns on
Squib Diagnosis
It checks not only high (4.50.5) or low (1.40.5) resistance but also short resistance (1- 10k) status between the
battery and ground to indicate defects in squib line by blinking warning lamp. Air bag control unit (AC4) can measure
squib resistance.
Warning Lamp Turning On
Air bag control unit detects system defects during ignition ON or driving and displays following 2 warning lamps.
- Warning lamp ON: internal defects of the air bag control unit
- Warning lamp blinking: higher resistance than standard in the squib line or short at the battery or ground,
Safety Function Check
It checks defects during operation of the arming sensor If the sensor is shorted for more than 2 seconds, the module
will enter overall shutdown mode.
Temperature Sensor
Function of the temperature sensor will be monitored continuously. If there is fault due to defective sensor or short,
the lamp will turn on and program will take calibration temperature (25) of collision conditions.
Power Supply
Airbag control unit operates in 9-16v and the characteristic of the system has backup condenser to supply the power
for max.150ms if there is power defect during collision.

Diagnosis
Air bag control unit diagnoses each function in the intervals of 250ms - 20 sec. during start-up or driving to prevent
unwanted air bag deployment. If there is defect, it turns on or blinks warning lamp to indicate defects in the air bag
system to the driver. And fatal defect is found, air bag control unit enters overall or partial shutdown status and fault
code will be stored.
Air bag control unit diagnoses following items.
- Ignition TR
- Acceleration
- Microprocessor, RAM and ROM
- Watchdog
- Shutdown Switch

During Driving
Lamp Blinking Mode
There are 2 kinds of blinking mode
1. When system internal fault is found, the lamp will stay on.
2. The lamp will blink according to external fault and there are 2 blinking codes.
Blinking code 1 (Squib resistance fault in the driver’s air bag squib line)
Blinking code 2 (Squib short on plus and minus in the air bag squib line)
Lamp blinking code is as follows. The last blinking will be within 0.5 sec. and 1 cycle of blinking will be repeated every
5 seconds.
Blinking Code 1
(Sec.) 0 0.5 1 1.5 2 2.5 3 3.5 4 4.5
