Most of these incidents can be repaired by adjusting, se curing or insulating the item(s) or component(s) caus-
ing the noise.
SUNROOF/HEADLINING
Noises in the sunroof/headlining area can often be traced to one of the following:
1. Sunroof lid, rail, linkage or seals making a rattle or light knocking noise
2. Sunvisor shaft shaking in the holder
3. Front or rear windshield touching headlining and squeaking
Again, pressing on the components to stop the noise while duplicating the conditions can isolate most of these
incidents. Repairs usually consist of insulating with felt cloth tape.
SEATS
When isolating seat noise it's important to note the pos ition the seat is in and the load placed on the seat when
the noise is present. These conditions should be duplic ated when verifying and isolating the cause of the
noise.
Cause of seat noise include:
1. Headrest rods and holder
2. A squeak between the seat pad cushion and frame
3. Rear seatback lock and bracket
These noises can be isolated by moving or pressing on the suspected components while duplicating the con-
ditions under which the noise occurs. Most of thes e incidents can be repaired by repositioning the component
or applying urethane tape to the contact area.
UNDERHOOD
Some interior noise may be caused by components under the hood or on the engine wall. The noise is then
transmitted into the passenger compartment.
Causes of transmitted underhood noise include:
1. Any component mounted to the engine wall
2. Components that pass through the engine wall
3. Engine wall mounts and connectors
4. Loose radiator mounting pins
5. Hood bumpers out of adjustment
6. Hood striker out of adjustment
These noises can be difficult to isolate since they cannot be reached from the interior of the vehicle. The best
method is to secure, move or insulate one component at a time and test drive the vehicle. Also, engine RPM
or load can be changed to isolate the noise. Repairs c an usually be made by moving, adjusting, securing, or
insulating the component causing the noise.

TROUBLE DIAGNOSIS
Diagnosis results previously stored in the memory are displayed on the CONSULT-III screen. The stored
results are not erased until memory erasing is executed.
 “TROUBLE DIAG RECORD”
With TROUBLE DIAG RECORD, diagnosis results previ ously erased by a reset operation can be displayed
on the CONSULT-III screen.
 “ECU DISCRIMINATED NO.”
The diagnosis sensor unit for each vehicle model is assigned with its own, individual classification number.
This number will be displayed on the CONSULT-III scr een, as shown. When replacing the diagnosis sensor
unit, refer to the part number for the compatibility. Af ter installation, replacement with a correct unit can be
checked by confirming this classification number on the CONSULT-III screen.
After repair, make sure the discriminated number of diagnosis sensor unit installed to vehicle are same.
Refer to SRS-44, "
Removal and Installation".
HOW TO CHANGE SELF-DIAGNOSIS MODE WITH CONSULT-III
From User Mode to Diagnosis Mode
After selecting “AIR BAG” on the “SELECT SYSTEM” screen, User mode automatically changes to Diagnosis
mode.
From Diagnosis Mode to User Mode
To return to User mode from Diagnosis mode, touch “BACK” key of CONSULT-III until “SELECT SYSTEM”
appears, then diagnosis mode automat ically changes to User mode.
HOW TO ERASE SELF-DIAGNOSTIC RESULTS
 “SELF-DIAG [CURRENT]”
A current self-diagnostic result is displayed on the CONSULT-III screen in real time.
After the malfunction is repaired completely, no malfunction is detected on “SELF-DIAG [CURRENT]”.
 “SELF-DIAG [PAST]” Return to the “SELF-DIAG [CURRENT]” CONSULT-III screen by touching “BACK” key of CONSULT-III and
select “SELF-DIAG [CURRENT]” in SELECT DIAG MODE. Touch “ERASE” in “SELF-DIAG [CURRENT]”
mode.
NOTE:
If the memory of the malfunction in “SELF-DIAG [P AST]” is not erased, the User mode shows the system
malfunction by the operation of the warning lamp even if the malfunction is repaired completely.
 “TROUBLE DIAG RECORD”
The memory of “TROUBLE DI AG RECORD” cannot be erased.

System DescriptionINFOID:0000000001327432
DESCRIPTION
 Electronic control allows optimal distribution of torque to front/rear wheels to match road conditions.
 Makes possible stable driving, with no wheel sp in, on snowy roads or other slippery surfaces.
 On roads which do not require AWD, it contributes to improved fuel economy by driving in conditions close to
rear-wheel drive.
 Sensor inputs determine the vehicle's turning conditi on, and in response tight cornering/braking are con-
trolled by distributing optimum torque to front wheels.
NOTE:
 When driving, if there is a large difference between front and rear wheel speed which continues for a long
time, fluid temperature of drive system parts becom es too high and AWD warning lamp flashes rapidly.
(When AWD warning lamp flashes, vehicle changes to r ear-wheel drive conditions.) Also, optional distribu-
tion of torque sometimes becomes rigid before lamp flashes rapidly, but it is not malfunction.
 If AWD warning lamp is flashing rapidly, stop vehicle and allow it to idle for some time. Flashing will stop and AWD system will be restored.
 When driving, AWD warning lamp may flash slowly if ther e is a significant difference in diameter of the tires.
At this time, vehicle performance is not fully avail able and cautious driving is required. (Continues until
engine is turned OFF.)
 If the warning lamp flashes slowly during driving but remains OFF after engine is restarted, the system is
normal. If it again flashes slowly after driving for some time, vehicle must be inspected.
 When the difference of revolution speed between the front and rear wheel mode the shift occasionally
changes to direct 4-wheel driving conditions automatically. This is not malfunction.

AWD SYSTEM
1. AWD control unit supplies command current to electric controlled coupling (AWD solenoid).
2. Control clutch is engaged by electromagnet and torque is detected in control clutch.
3. The cam operates in response to control clutch torque and applies pressure to main clutch.
4. Main clutch transmits torque to front wheels according to pressing power.  Transmission torque to front wheels is determined accordingto command current.
AWD CONTROL UNIT
 Controls distribution of drive power between rear-wheel drive(0:100) and AWD (50:50) conditions according to signals from sen-
sors.
 Self-diagnosis can be done with CONSULT-III.
AWD WARNING LAMP
Turns ON when there is a malfunction in AWD system. It indicates that fail-safe mode is engaged and vehicle
change to rear-wheel drive or shifting driving force- AWD (Front-wheels still have some driving torque).
Also turns ON when ignition switch is turned ON, for purpose of lamp check. Turns OFF approximately for 1
seconds after the engine starts if system is normal.
