REMOVAL
CAUTION:
lBefore servicing the SRS, turn the ignition switch off, disconnect both battery cables and wait at
least 3 minutes.
1. Disconnect the connectors for each air bag module and seat belt pre-tensioner.
2. Remove center console. Refer toIP-10, "
INSTRUMENT PANEL ASSEMBLY".
3. Disconnect diagnosis sensor unit connectors.
4. Remove bolts from the diagnosis sensor unit.
CAUTION:
lDo not use old bolts; replace with new bolts.
lCheck diagnosis sensor unit bracket to ensure it is free of deformities, dents, cracks or rust. If it
shows any visible signs of damage, replace with new one.
lReplace diagnosis sensor unit if it has been dropped or sustained an impact.
INSTALLATION
Install in the reverse order of removal.
lAfter the work is completed, perform self-diagnosis to check that no malfunction is detected. Refer to
SRS-18, "
SRS Operation Check".
CAUTION:
lThe diagnosis sensor unit must always be installed with the arrow mark "Ü" pointing toward the
front of the vehicle for proper operation.
ECU DISCRIMINATED NO.
After replacing the diagnosis sensor unit, confirm that the diagnosis sensor unit identification is correct for the
vehicle as equipped. Refer toSRS-16, "
CONSULT-II Function".

PRECAUTIONS
If 4WD shift indicator lamp and 4LO indicator lamp do not indicate proper pattern, install new transfer con-
trol unit and retry the above check.
PrecautionsEDS0031B
lBefore connecting or disconnecting the transfer control unit harness connector, turn ignition
switch “OFF” and disconnect the battery cables. Battery voltage is applied to transfer control unit
even if ignition switch is turned “OFF”.
lWhen connecting or disconnecting pin connectors into or
from transfer control unit, take care not to damage pin ter-
minals (bend or break).
When connecting pin connectors make sure that there are
not any bends or breaks on transfer control unit pin termi-
nals.
lBefore replacing transfer control unit, perform transfer con-
trol unit input/output signal inspection and make sure
whether transfer control unit functions properly or not.
Refer toTF-38, "
Transfer Control Unit Input/Output Signal
Reference Values".
Service NoticeEDS0031C
lAfter overhaul refill the transfer with new transfer fluid.
lCheck the fluid level or replace the fluid only with the vehicle parked on level ground.
lDuring removal or installation, keep inside of transfer clear of dust or dirt.
lDisassemblyshouldbedoneinacleanworkarea.
lBefore proceeding with disassembly, thoroughly clean the transfer. It is important to prevent the internal
parts from becoming contaminated by dirt or other foreign matter.
lCheck for the correct installation status prior to removal or disassembly. If matchmarks are required, be
certain they do not interfere with the function of the parts when applied.
lAll parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection or
reassembly.
lCheck appearance of the disassembled parts for damage, deformation, and unusual wear. Replace them
with a new ones if necessary.
lGaskets, seals and O-rings should replaced any time the transfer is disassembled.
lIn principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If
tightening sequence is specified, use it.
lObserve the specified torque when assembling.
lClean and flush the parts sufficiently and blow-dry them.
lBe careful not to damage sliding surfaces and mating surfaces.
lUse lint-free cloth or towels for wiping parts clean. Common shop rags can leave fibers that could interfere
with the operation of the transfer.

1. Check tires for wear and improper inflation.
2. Check wheels for deformation, cracks and other damage. If
deformed, remove wheel and check wheel runout.
a. Remove tire from wheel and mount wheel on a tire balance
machine.
b. Set dial indicator as shown in the illustration.
3. Check front wheel bearings for looseness.
4. Check front suspension for looseness.
STEEL WHEEL
1. Check tires for wear and improper inflation.
2. Check wheels for deformation, cracks and other damage. If
deformed, remove wheel and check wheel runout.
a. Remove tire from steel wheel and mount wheel on a tire balance
machine.
b. Set two dial indicators as shown in the illustration.
c. Set each dial indicator to 0.
d. Rotate wheel and check dial indicators at several points around
the circumference of the wheel.
e. Calculate runout at each point as shown below.
f. Select maximum positive runout value and the maximum nega-
tive value.
Add the two values to determine total runout.
In case a positive or negative value is not available, use the
maximum value (negative or positive) for total runout.
If the total runout value exceeds the limit, replace steel wheel.Wheel runout (Dial indicator value):
Refer toWT-6, "
SERVICE DATA AND SPECIFICA-
TIONS (SDS)"SFA975B
Radial runout = (A+B)/2 : 0.5 mm (0.020 in)
Lateral runout = (C+D)/2 : 0.8 mm (0.031 in)

MIST OPERATION
When the wiper switch is temporarily placed in the mist position, wiper low speed operation cycles once and
then stops.
For additional information about wiper operation under this condition, refer toWW-5, "
LOW SPEED WIPER
OPERATION".
If the switch is held in the mist position, low speed operation continues.
FAIL-SAFE FUNCTION
The BCM includes fail-safe function to prevent malfunction of electrical components controlled by CAN com-
munications if a malfunction in CAN communications occurs.
The BCM uses CAN communications to stop output of electrical components it controls.
Until the ignition switch is turned OFF, the front wiper system remains in same status as just before fail-safe
control was initiated. (If wiper was in low speed operation just before fail-safe, it continues low speed operation
until ignition switch is turned OFF.)
When fail-safe status is initiated, the BCM remains in standby until normal signals are received.
When normal signals are received, fail-safe status is canceled.
