6. Inspection of the SRS-ECU harness connector should be carried out by the following procedure.
Insert the special tool (probe, MB991222, in the harness set) into the connector from harness side
(rear side), and connect the tester to this probe. If any tool than specified is used, damage to the
harness and other components will result. Furthermore, measurement should not be carried out by
touching the probe directly against the terminals from the front of the connector. The terminals are
plated to increase their conductivity, so that if they are touched directly by the probe, the plating
may break, which will cause drops in reliability.

7. SRS components and seat belt with pre-tensioner should not be subjected to hart, so remove the
SRS-ECU, driver’s and front passenger’s air bag modules, clock spring, and seat belt with pre-tensioner
before drying or baking the vehicle after painting.

8. Whenever you finish servicing the SRS, check warning lamp operation to make sure that the system
functions properly. (Refer to P.52B-6.)
9. Make certain that the ignition switch is LOCK (OFF) position when the MUT-IIis connected or
disconnected.
10. If you have any questions about the SRS, please contact your local distributor.
NOTE
SERIOUS INJURY CAN RESULT FROM UNINTENDED AIR BAG DEPLOYMENT, SO USE ONLY
THE PROCEDURES AND EQUIPMENT SPECIFIED IN THIS MANUAL.

THROTTLE BODY (THROTTLE VALVE AREA)
CLEANING
1. Remove the air intake hose from the throttle body.
2. Spray cleaning fluid on a clean cloth.
3. Wipe off the dirt around the throttle valve with the cloth
sprayed with cleaning fluid.
Caution
(1) Do not spray the cleaning fluid directly to the
throttle valve.
(2) Make sure the cleaning fluid does not enter the
motor from the bypass line. Also make sure it
does not enter the sensor through the shaft.
(3) Be careful not to rub off the molybden applied
around the throttle valve shaft.
4. Attach the air intake hose.
5. Adjust the basic idle speed. (Refer to P.13A-127.)
THROTTLE POSITION SENSOR ADJUSTMENT
1. Connect the MUT-IIto the diagnosis connector.
When not using the MUT-II, proceed as follows:
(1) Disconnect the throttle position sensor connector, and
connect the special tool (test harness: MB991536)
between the disconnected connector taking care not
to confuse the terminal to be connected.
(2) Connect digital voltmeter between the terminal No.
2 and the terminal No. 4 of the throttle position sensor
connector.
2. Turn the ignition switch to “ON” position (but do not start
the engine).
3. Check the output voltage of the throttle position sensor.
Standard value: 535 - 735 mV

NOTE
The voltage waveform of the alternator B terminal can undulate
as shown at left. This waveform is produced when the regulator
operates according to fluctuations in the alternator load
(current), and is normal for the alternator.
In addition, when the voltage waveform reaches an
excessively high value (approximately 2 V or higher at idle),
it often indicates an open circuit due to a brown fuse between
alternator B terminal and battery, but not a defective alternator.

Torque transfer mechanism part
1. Remove the drive shaft. (Refer to P. 27B-29.)
2. Remove the oil seal from the differential carrier.
3. Using the special tool, drive a new oil seal all the way
into position.
4. Coat the oil seal lips and the drive shaft surface in contact
with the oil seal with the specified grease.
Specified grease: Vaseline
5. Replace the drive shaft circlip with a new one and mount
the drive shaft to the differential carrier. (Refer to P.
27B-29.)
6. Check for correct wheel alignment. (Refer to GROUP
34 – On-vehicle Service.)
ACTION WHEN BATTERY RUNS OUT
When the engine is started using a booster cable where the
battery has completely run down and you attempt to start
the vehicle without waiting for the battery to recover a certain
charge, the engine can misfire and you just cannot start to
move it. In such cases, charge the battery sufficiently; or,
remove the AYC battery cable from the battery fuse assembly
to make AYC inactive before attempting to start the vehicles.
When the battery cable is removed, the ACD mode indicator
lamp lights up. After the battery has been recharged, fit the
battery cable back again and start the engine to ensure that
the ACD mode indicator lamp is off.

INSPECTION
DIFFERENTIAL CASE INTERNAL PARTS CONTACT/
SLIDING SURFACE CHECK
1. Clean the disassembled parts with cleaning oil and dry
them with compressed air.
2. Check each plate, disc, and pressure ring for the following:
A. Friction and sliding surfaces of friction discs, friction
plates, and spring plates.
Replace a defective part with heat discoloration and
excessive wear with a new one, as it degrades locking
performance.
NOTE
If the inner periphery of the friction face shows traces
of harsh contact, it is because of the spring tension
of each plate, disc and other part. Do not confuse
this with abnormal wear.
B. Inner periphery and outer periphery protrusions of
friction discs, friction plates, and spring plates.
Replace a cracked or damaged part with a new one.
C. Friction and sliding surfaces between pressure rings
and friction discs.
Grind a dented or scratched part with oil stone and
then lap and correct with a compound on a surface
plate.
NOTE
If the inner periphery of the friction face shows traces
of harsh contact, it is because of the spring tension
of each plate, disc and other part. Do not confuse
this with abnormal wear.
3. Check the following parts for contact and siding surfaces
(D to M) and correct burrs and dents with oil stone.
D: Sliding surfaces of side gear and case
E: Contacting surfaces of differential case and spring
plate
F: Contacting surfaces of pressure ring and differential
case inner face
G: Sliding surfaces of pressure ring hole and side gear

DOOR OUTSIDE HANDLE LOOSENESS
CHECK
1. Check that the looseness of the door outside handle
satisfies the standard value.
Standard value (A):
Front 2.3±2.1 mm
Rear 1.3±1.7 mm
2. Check the door outside handle and door latch assembly.
If faulty, replace.
POWER WINDOW OPERATING CURRENT
CHECK
1. Remove the power window fuse, and connect the circuit
tester as shown in the figure.
2. When the power window switch is set to the UP side,
a large amount of operating current flows when the window
is operated or closed. Therefore measure somewhere
in between excluding these positions.
Standard value: 5±1A (Power supply voltage
14.5±0.5 V, 25_C)
3. If outside the standard value, perform troubleshooting.
(Refer to GROUP 54B.)
CIRCUIT BREAKER CHECK (Incorporated in
the power window motor)
1. Set the power window switch to the UP side until the
window glass closes completely, and continue operating
the switch for more than 10 seconds.
2. Release the power window switch at the UP side, and
at the same time, press the DOWN side. Under this
condition if the window glass starts to lower within 60
seconds, the circuit breaker can be determined as good.
POWER WINDOW CHECK
Check that the power window operates. If it does not, perform
troubleshooting. (Refer to GROUP 54B.)
