A/C System Inspection at ECMS7RS0B7224028
Voltage Check
ECM and its circuits can be checked by measuring voltage with special tool connected.
CAUTION!
• ECM connectors are waterproofed. Each terminal of the ECM connectors is sealed up with the
grommet. Therefore, do not measure circuit voltage and resistance by inserting the tester’s probe
into the sealed terminal at the harness side. Or, ECM and its circuits may be damaged by water.
• ECM cannot be checked by itself. It is strictly prohibited to connect voltmeter or ohmmeter to ECM with couplers disconnected from ECM.
1) Remove ECM (1) from its bracket by referring to “Electric Throttle Body System Calibration in Section 1C”.
2) Connect special tool (2) between ECM and ECM connectors securely.
3) Check voltage at each terminal.
NOTE
As each terminal voltage is affected by the battery voltage, confirm that the battery voltage is 11 V or
more when ignition sw itch is ON position.

Precautions on Handling and Storage of Air Bag
System Components
S7RS0B8200002
SDM
WARNING!
Never power up air bag system when SDM is
not rigidly attached to the vehicle. Otherwise,
personal injury may result.
CAUTION!
After detecting one time of such collision as
to meet deployment conditions, SDM must
not be used. Refer to “Air Bag Diagnostic
System Check” when checking SDM.
• Never attempt disassembly of SDM.
• When storing SDM, select a place where neither high temperature nor high humidity is anticipated and oil,
water and dust are kept off.
• If SDM has been dropped, replace it with a new one.
• If SDM installation part of floor was damaged, repair that part completely before reinstallation.
• All SDM and mounting bracket fasteners must be carefully torqued and the arrow must be pointed
toward the front of the vehicle to ensure proper
operation of the air bag system. Live (Undeployed) Air Bag (Inflator) Modules
Special care is necessary when handling and storing a
live (undeployed) air bag (inflator) modules.
The rapid gas generation produced during deployment
of the air bag could cause the air bag (inflator) module,
or an object in front of the air bag (inflator) module, to be
thrown through the air in the unlikely event of an
accidental deployment.
WARNING!
Never attempt to measure the resistance of
the air bag (inflator) modules (driver,
passenger and side of both sides and curtain
of both sides). It is
very dangerous as the
electric current from the tester may deploy
the air bag.

Downloaded from www.Manualslib.com manuals search engine Air Bag System: 8B-3
• Never attempt disassembly of the air bag (inflator) modules.
• If any abnormality is found, be sure to replace it with
new one as an assembly.
• When an abnormality is noted as existing in the live (undeployed) air bag (inflator) module, be sure to
deploy it before discarding it.
• When grease, cleaning agent, oil, water, etc., got on the air bag (inflator) modules (driver, passenger, side
of both sides and curtain of both sides), wipe it off
immediately with a dry cloth.
• If air bag (inflator) module was dropped from a height of 90 cm (3 ft) or more, it should be replaced with a
new one as an assembly.
WARNING!
• 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.
Otherwise, personal injury may result.
WARNING!
When placing a live air bag (inflator) module
on 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.
Live (Inactivated) Seat Belt Pretensioner
Special care is necessary when handling and storing a
live (inactivated) seat belt pretensioners.
Also, when the seat belt pretensioners activate, gas is
generated and the seat belt (1) is retracted into the
retractor assembly (2) quickly.
Note, therefore, that if they activate accidentally, the seat
belt pretensioners and other object(s) around them may
be thrown through the air.

Repair and Inspection Required after AccidentS7RS0B8204049
CAUTION!
• All air bag system components, including the electrical harness (component
mounting points), must be inspected after
an accident. If any components are
damaged or bent, they must be replaced
even if air bag system activation did not
occur.
• Never use air bag system parts from another vehicle.
• Do not attempt to service the parts below. Service of these parts is by replacement
only.
– Driver / Passenger air bag (inflator) modules
– Driver / Passenger side-air bag (inflator) modules
– Driver / Passenger side curtain-air bag (inflator) modules
– Driver / Passenger seat belt pretensioners
–Forward-sensor
– Driver / Passenger side-sensors
–SDM
– Contact coil and combination switch assembly
– Air bag wire harness in main harness, instrument panel harness and floor
harness.
• Proper operation of the sensors and air bag system requires that any repairs to the
vehicle structure return it to its original
production configuration.
CAUTION!
After detecting one time of such collision as
to meet deployment conditions, the SDM
must not be used.
Refer to “Air Bag Diagnostic System Check”
when checking the SDM.
Accident with Deployment / Activation – Component
Replacement
When driver and passenger air bags are deployed, the
following components must be replaced.
• Driver and passenger air bag (inflator) modules
• Driver and passenger seat belt pretensioners
• SDM after detecting such collision as to meet
deployment conditions
• Forward-sensor
• Instrument panel When side-air bag and side curtain-air bag are deployed,
the following components must be replaced.
• Deployed side-air bag (inflator) module
• Deployed side curtain-air bag (inflator) module
• Side-sensor
•SDM
Accident with or without Deployment / Activation –
Component Inspections
Certain air bag and restraint system components must
be inspected after any crash, whether the air bag system
activated or not. If any faul
ty condition is found in the
following checks, replace faulty part.
Those components are:
• Steering column (1) and shaft joints
– Check for length, damage and bend according to “Checking Steering Column for Accident Damage in
Section 6B”.
• Steering column bracket (2) and capsules – Check for damage and bent.
• Steering wheel and driver air bag (inflator) module – Check for damage or air bag (inflator) module fitness.
– Check trim cover (pad surface) for cracks.
– Check wire harness and connector for damage or tightness.
