Servicing and Handling
WARNING!
Many of service procedures require
disconnection of “A/B” fuse and all air bag
(inflator) module(s) from initiator circuit to
avoid an accidental deployment.
Driver, Passenger, Side and Curtain Air Bag
(Inflator) Modules
• For handling and storage of a live air bag
(inflator) module, select a place where the
ambient temperature below 65 °C (150 °F),
without high humidity and away from
electric noise.
• When carrying a live air bag (inflator)
module, make sure the bag opening is
pointed away from you. In case of an
accidental deployment, the bag will then
deploy with minimal chance of injury.
Never carry the air bag (inflator) module by
the wires or connector on the underside of
the module. When placing a live air bag
(inflator) module on a bench or other
surface, always face the bag up, away from
the surface. As the live passenger air bag
(inflator) module must be placed with its
bag (trim cover) facing up, place it on the
workbench with a slit (1) or use the
workbench vise (2) to hold it securely at its
lower mounting bracket (3). It is also
prohibited to place anything on top of the
trim cover and stack air bag (inflator)
modules. This is necessary so that a free
space is provided to allow the air bag to
expand in the unlikely event of accidental
deployment. Otherwise, personal injury
may result.
• Never dispose of live (undeployed) air bag
(inflator) modules (driver, passenger, side
and curtain). If disposal is necessary, be
sure to deploy them according to
deployment procedures described in “Air
Bag (Inflator) Module and Seat Belt
Pretensioner Disposal in Section 8B”
before disposal.
• The air bag (inflator) module immediately
after deployment is very hot. Wait for at
least half an hour to cool it off before
proceeding the work.• After an air bag (inflator) module has been
deployed, the surface of the air bag may
contain a powdery residue. This powder
consists primarily of cornstarch (used to
lubricate the bag as it inflates) and by-
products of the chemical reaction. As with
many service procedures, gloves and
safety glasses should be worn.
[A]: Always carry air bag (inflator) module with trim cover (air bag opening)
away from body.
[B]: Always place air bag (inflator) module on workbench with trim cover (air
bag opening) up, away from loose objects.

WARNING!
SDM
• For handling and storage of a SDM, select
a place where the ambient temperature
below 65 °C (150 °F), without high humidity
and away from electric noise.
• During service procedures, be very careful
when handling a Sensing and Diagnostic
Module (SDM). Never strike or jar the SDM.
• Never power up the air bag system when
the SDM is not rigidly attached to the
vehicle. All SDM and mounting bracket
fasteners must be carefully torqued and
the arrow must be pointing toward the
front of the vehicle to ensure proper
operation of the air bag system.
The SDM could be activated when powered
while not rigidly attached to the vehicle
which could cause deployment and result
in personal injury.
WARNING!
Driver and Passenger Seat Belt
Pretensioners
• For handling and storage of a live seat belt
pretensioner, select a place where the
ambient temperature below 65 °C (150 °F),
without high humidity and away from
electric noise.
• Never carry seat belt pretensioner by wire
or connector of pretensioner. When
placing a live seat belt pretensioner on the
workbench or some place like that, never
put something on seat belt pretensioner.
Otherwise, personal injury may result.
• Never dispose of live (inactivated) seat belt
pretensioners (drive and passenger). If
disposal is necessary, be sure to activate
them according to activation procedures
described in “Air Bag (Inflator) Module and
Seat Belt Pretensioner Disposal in Section
8B” before disposal.
• The seat belt pretensioner immediately
after activation is very hot. Wait for at least
half an hour to cool it off before
proceeding the work.
• With many service procedures, gloves and
safety glasses should be worn to prevent
any possible irritation of the skin or eyes.
• Even when the accident was light enough not to
cause air bags to activate, be sure to inspect system
parts and other related parts according to instructions
under “Repair and Inspection Required after Accident
in Section 8B”.
• When servicing parts other than air bag system, if
shocks may be applied to air bag system component
parts, remove those parts beforehand.
• When handling the air bag (inflator) modules (driver,
passenger, side and curtain), seat belt pretensioners
(driver and passenger), forward sensor, side sensors
or SDM, be careful not to drop it or apply an impact to
it. If an excessive impact was applied, never attempt
disassembly or repair but replace it with a new one.
• When grease, cleaning agent, oil, water, etc. has got
onto air bag (inflator) modules (driver, passenger, side
and curtain) or seat belt pretensioners (drive and
passenger), wipe off immediately with a dry cloth.
• Air bag wire harness is included in floor and
instrument panel wire harnesses. Air bag wire
harness branched off from floor and instrument panel
wire harnesses can be identified easily as it is covered
with a yellow protection tube and it has yellow
connectors. Be very careful when handling it.
• When an open in air bag wire harness, damaged wire
harness, connector or terminal is found, replace wire
harness, connectors and terminals as an assembly.
• Do not apply power to the air bag system unless all
components are connected or a diagnostic flow
requests it, as this will set a DTC.
• Never use air bag system component parts from
another vehicle.
• When using electric welding, be sure to disconnect all
air bag (inflator) module connectors and pretensioner
connectors from air bag wire harness respectively.
• Never expose air bag system component parts
directly to hot air (drying or baking the vehicle after
painting) or flames.
• WARNING / CAUTION labels are attached on each
part of air bag system components. Be sure to follow
the instructions.
• After vehicle is completely repaired, perform “Air Bag
Diagnostic System Check in Section 8B”.
General PrecautionsS6RW0D0000002
The WARNING and CAUTION describe some general
precautions that you should observe when servicing a

Air Intake System DescriptionS6RW0D1101006
The main components of the air intake system are air cleaner (1), air cleaner outlet hose (2), electric throttle body (3)
(for the details, refer to “Description of Electric Throttle Body System”.), and intake manifold (4).
The air (by the amount corresponding to throttle valve (5) opening and engine speed) is filtered by the air cleaner,
distributed by the intake, and finally drawn into each combustion chamber. Electric throttle body is not equipped with
IAC valve for idle speed control. Idle speed control is done by the throttle actuator (6) which opens/closes the throttle
valve. (For the details, refer to “Description of Electric Throttle Body System”.)
Description of Electric Throttle Body System CalibrationS6RW0D1101007
ECM calculates controlled opening of the throttle valve on the basis of the completely closed throttle valve position of
the electric throttle body system. The completely closed position data is saved in memory of ECM. However, the
completely closed position of the throttle valve of the electric throttle body system (signal voltage from throttle position
sensor when throttle is completely closed) differs one from the other depending on individual differences of the throttle
valve and throttle position sensor. As such individual differences must be taken into account for controlling the throttle
valve, it is necessary to register the completely closed throttle valve position data in ECM. When such data is
registered in ECM, it is saved in RAM (memory) of ECM and used as the base data for controlling the throttle valve.
This data is cleared, when any of the works described in “Precautions of Electric Throttle Body System Calibration” is
performed.
Also, after replacement of the throttle body and/or APP sensor assembly, the completely closed position data in
memory of ECM must be cleared once and a new one must be registered, or ECM cannot judge the complete closure
position properly.
For the procedure to register such data, refer to “Electric Throttle Body System Calibration in Section 1C”. (After the
completely closed position data is cleared, ECM, for the first time only, opens and closes the throttle valve for about 5
seconds after the ignition switch is turned ON position, for registration of the completely closed throttle valve position.
If the engine is started during this registration process, such symptom as “longer cranking time” or “slow rise of
revolution speed immediately after start-up” may occur. However, turning OFF the ignition switch once and restarting
will set correct registration.)
Description of Electric Throttle Body SystemS6RW0D1101009
The Electric Throttle Body System consists of electric throttle body assembly, accelerator pedal position (APP) sensor
assembly, ECM and throttle actuator control relay.
Among them, assembly components are as follows.
• Electric throttle body assembly: throttle valve, throttle actuator, 2 throttle position sensors
• APP sensor assembly: Accelerator pedal, 2 accelerator position sensors
