3. Check the connector for damage and deformed terminals,
and check the harness for binding.
4. Check the air bag inflator case for dents, cracks or
deformation.
5. Check the harness (built into the steering wheel) and
connectors for damage, and check the terminals for
deformation.
6. Check the clock spring connectors and protective tube for
damage, and terminals for deformities.
7. Visually check the case for damage.
If the clock spring's mating mark is not properly
aligned, the steering wheel may not completely rotate
during turn, or the flat cable within the clock spring
may be severed, obstructing normal operation of the
SRS and possibly lead to serious injury to the vehi-
cle's driver and front passenger.
8. Align the mating marks of the clock spring first. After turning
the front wheels to the straight-ahead position, install the
clock spring to the column.
Mating Marks Alignment;
After turning the clock spring fully clockwise, turn it
approximately 3 3/4 turns counterclockwise until the mating
marks are aligned.
9. Install the steering column covers, steering wheel and air
bag module (Refer to GROUP 52B, Air Bag Module and
Clock Spring P.52B-237).
10.Check the steering wheel for noise, binding or difficult
operation.

The SRS may not activate if any of the above compo-
nents are not installed properly, which could result in
serious injury or death to the vehicle's driver and
front passenger.
11.Check the steering wheel for excessive free play.
Replace any part if it fails visual inspection (Refer to
GROUP 52B, Air Bag Module and Clock Spring P.52B-237).
FRONT SEATBACK ASSEMBLY WITH
SIDE-AIRBAG MODULE
If any improper part is found during the following
inspection, replace the front seatback assembly
with a new one.
Dispose of the old one according to the specified
procedure (Refer to GROUP 52B, Air Bag Module
Disposal Procedures P.52B-254).
Never attempt to measure the circuit resistance of
the air bag module (squib) even if you are using
the specified tester. If the circuit resistance is mea-
sured with a tester, accidental air bag deployment
will result in serious personal injury.
1. Check the air bag module deployment section for dents or
deformation.
2. Check the connector for damage; Check the terminals for
deformation; and check the harness for binding.
Replace the front seat if it fails the visual checks above
(Refer to GROUP 52A, Front Seat P.52A-33).
SEAT BELT WITH PRE-TENSIONER
If the seat belt pre-tensioner is not installed
securely and correctly, the seat belt pre-tensioner
may not operate normally.
If a dent, crack, deformation or rust is detected,
replace with a new seat belt pre-tensioner.
1. Check the seat belt pre-tensioner for dents or deformation.
2. Check that the seat belt pre-tensioner is installed correctly to
the vehicle body.
Replace the seat belt pre-tensioner if it fails the visual
checks above (Refer to GROUP 52B, Seat Belt
Pre-tensioner P.52B-250).

20. TYRES (ROTATE)M1001008900303
Rotate tyres regularly to equalize tyre wear and help extend
tyre life. Recommended tyre rotation is every 12,000 km under
normal driving conditions and every 9,600 km in severe driving
conditions.
Timing for the rotation may vary according to vehicle condition,
road surface conditions, and individual driver's habits.
When rotating tyres, check for uneven wear, damage, and
wheel alignment. Abnormal wear is usually caused by incorrect
tyre pressure, improper wheel alignment, out-of balance
wheels, or severe braking.
The first rotation is the most important, to achieve more uniform
wear for all tyres on the vehicle.

GENERAL DESCRIPTION
TRACTION CONTROL SYSTEM (TCL)13C-2
GENERAL DESCRIPTIONM1136000100029
Traction Control systems are a significant safety fea-
ture designed to prevent wheel spin during accelera-
tion. This results in improved vehicle stability and
steer ability. When excessive wheel spin is detected,
the system will automatically reduce engine torque
via the engine management system. The Engine
ECU can reduce throttle position, cut fuel injection
and retard ignition to one or more cylinders depend-ing on how much torque reduction is required and
will continue to occur until the wheels are no longer
spinning. During traction control operation the TCL
warning lamp will flash to inform the driver that the
vehicle is under traction control. This will continue
until traction control is finished.

INTRODUCTION TO TRACTION CONTROL SYSTEM (TCL) DIAGNOSISM1136004600026
TCL Diagnostic Trouble Code Detection
Conditions
TCL diagnostic trouble codes (TCL DTCs) are set
under different conditions, depending on the mal-
function detected. Most TCL DTCs will only be set
during vehicle operation. Some TCL DTCs will also
be set during the TCL self-check immediately after
the engine is started. When you check if an TCL DTC will be displayed again after the DTC has been
erased, you should recreate the TCL DTC set condi-
tions. Depending on the detection timing and set
conditions for the specific TCL DTC, you must either
drive the vehicle or turn the engine off and restart it.
To set the proper conditions for that DTC again, refer
to "TCL DTC SET CONDITIONS" for each TCL DTC
that you are trying to reset.
TROUBLESHOOTING STRATEGYM1136003100062
Use these steps to plan your diagnostic strategy. If
you follow them carefully, you will check most of the
possible causes of a TCL problem.
1. Gather information from the customer.
2. Verify that the condition described by the
customer exists.
3. Check the vehicle for any TCL DTC. (Refer to
P.13C-3, Diagnosis Function
How to Read and
Erase Diagnostic Trouble Codes).
4. If you can verify the condition but no TCL DTCs
are set, and the malfunction may be intermittent.
(Refer to GROUP 00, How to Use
Troubleshooting/Inspection Service Points
How
to Cope with Intermittent Malfunctions P.00-14).
5. If you can verify the condition but there is no TCL
DTCs, or the system cannot communicate with
diagnostic tool MB991958 (MUT-III sub
assembly), and find the fault. (Refer to P.13C-23,
Symptom Chart).6. If there is a TCL DTC, record the number of the
code, then erase the code from vehicle memory
using the diagnostic tool MB991958 (MUT-III sub
assembly). (Refer to P.13C-3, Diagnosis Function
How to Read and Erase Diagnostic Trouble
Codes).
7. Re-create the TCL DTC set conditions to see if
the same TCL DTC will set again. (Refer to
P.13C-3, Diagnosis Function
How to Read and
Erase Diagnostic Trouble Codes).
If the same TCL DTC sets again, perform the
diagnostic procedures for the set code. (Refer to
P.13C-8, Diagnostic Trouble Code Chart).
NOTE: If the ABS-8 ECU or the active wheel
speed sensor are disconnected, or if the wir-
ing is an open/ short circuit, the ABS 8 ECU
will shut off power supply to the respective
wheel speed sensor. All other wheel speed
sensors will operate normally. To restore the
power supply, the ignition switch must be
turned to the "OFF" position then to the "ON"
position again.

DIAGNOSTIC TROUBLE CODE CHARTM1136003300022
During diagnosis, a DTC associated with other
system may be set when the ignition switch is
turned on with connector(s) disconnected. On
completion, confirm all systems for DTC(s). If
DTC(s) are set, erase them all.
NOTE: If the ABS-8 ECU or the active wheel
speed sensor are disconnected, or if the wiring is
an open/ short circuit, the ABS 8 ECU will shut
off power supply to the respective wheel speed
sensor. All other wheel speed sensors will oper-
ate normally. To restore the power supply, the
ignition switch must be turned to the "OFF" posi-
tion then to the "ON" position again.Follow the inspection chart that is appropriate for the
diagnostic trouble code.
