SRS – Air Bag Module Disposal Procedures52B-39
(1) Remove the air bag module from the vehicle.
(Refer to P.52B-27.)
Caution
The connector of the front passenger’s side air
bag module is so constructed that the positive
and negative terminals are automatically
short-circuited when it is disconnected to prevent
an accidental deployment of the air bag resulting
from static electricity generation. Nevertheless,
to eliminate the slightest possibility of an
accidental deployment, always bear the following
in mind; the air bag module should be stored on
a flat surface and placed so that the pad cover
face up. Anything should not be placed on top
of it.
(2) Connect two wires, each six meters or longer, to the
two leads of SRS air bag adapter harness A and
cover the connections with insulation tape. The other
ends of the two wires should be connected to each
other (short-circuited), to prevent sudden unexpected
deployment of the air bag module.
(3) Connect the deployment wires to the SRS air bag
adaptor harness A, pass it beneath the tyre, and
wheel assembly, and connect it to the air bag module.
(4) Pass the thick wires into the hole of the air bag module
bracket, and secure it to the wheel of the old tyre
with wheel (4 locations), with the air bag facing
upwards.
Caution
1) Leave some space below the wheel for the
deployment wires.
If there is no space, the reaction of the air
bag deployment could result in damage of
the adaptor harness.
2) While deployment takes place, do not have
the connector of the SRS air bag adaptor
harness A inserted between the tyres.

(5) Place three old tyres, without wheels, on top of the
tyre secured to the air bag module, and secure all
tyres with ropes (4 locations).
NOTE
The front passenger’s side air bag is larger in capacity
than the driver’s side air bag when deployed. For
this reason, it is necessary to tie up all tyres together
with rope.
(6) At a location as far away from the air bag module
as possible, and from a shielded position, disconnect
the two connected wires from each other, and connect
them to the two terminals of the battery (which has
been removed from the vehicle) to deploy the air
bag.
Caution
1) Before deployment, check carefully to be sure
that no one is nearby.
2) The inflator will be quite hot immediately
following the deployment, so wait at least 30
minutes to allow it to cool before attempting
to handle it. Although not poisonous, do not
inhale gas from air bag deployment. See
Deployed Air Bag Module Disposal
Procedures (P.52B-40) for post-deployment
handling instructions.
3) If the air bag fails to deploy when the
procedures above are followed, do not go near
the module. Contact your local distributor.
(7) After deployment, dispose of the air bag module
according to the Deployed Air Bag Module Disposal
Procedures.
DEPLOYED AIR BAG MODULE DISPOSAL
PROCEDURES
After deployment, the air bag module should be disposed
of in the same manner as any other scrap parts, adhering
to local laws and/or legislation that may be in force except
that the following points should be carefully noted during
disposal.
1. The inflator will be quite hot immediately following
deployment, so wait at least 30 minutes to allow it cool
before attempting to handle it.
2. Do not put water or oil on the air bag after deployment.

INSPECTION PROCEDURE FOR TROUBLE SYMPTOMS
Inspection Procedure 1
Speedometer does not work.
Probable cause
Examine the diagnosis codes registered in the engine-ECU. If no wheel speed
sensor-relating diagnosis code has been output, the wheel speed sensors are in order.Malfunction of vehicle speed sensor
Malfunction of speedometer
Malfunction of harness or connector
Malfunction of relevant ECU
Disconnect the combination meter con-
nectors B-08 or B-09 and measure at
the harness sides.
1. Continuity between the terminal
No.11 and earth
OK: Continuity
2. Voltage between terminal No.51 and

ON-VEHICLE SERVICE
SPEEDOMETER CHECK
1. Adjust the pressure of the tyres to the specified level.
2. Set the vehicle onto a speedometer tester and use wheel
chocks to hold the rear wheels.
3. Pull the parking brake lever firmly.
4. To prevent the front wheel from moving from side to side,
attach tension bars to the tie-down hook, and secure
both ends to anchor plates.
5. To prevent the vehicles from starting, attach a chain or
wire to the rear towing hook, and secure the other end
of the chain or wire firmly to an unmovable body.
6. Check if the speedometer indication range is within the
standard values and if the pointer fluctuation is within
the limits.
Caution
Do not operate the clutch suddenly. Do not
increase/decrease speed rapidly while testing.
Standard values:
Vehicle speed km/hSpeedometer indication
allowable errors km/h
4037 – 45
8075 – 88
120113 – 132
160150 – 176
Limit: Pointer fluctuation
(at vehicle speeds of higher than 35 km/h) ±3 km/h
TACHOMETER CHECK
1. Insert a paper clip in the engine speed detection connector
from the harness side, and attach the engine
speedometer.
2. Compare the readings of the engine speedometer and
the tachometer at every engine speed, and check if the
variations are within the standard values.
Standard values:
700 r/min : ±100 r/min
3,000
*1 r/min : ±150 r/min
3,000*2 r/min : +225 to –100 r/min
