1) Check for loose each connection.
Is it connected securely?Go to Step 3. Intermittent trouble.
Check for intermittent
trouble referring to
“Inspection of
Intermittent and Poor
Connections” If OK,
substitute a known-
good SDM and recheck.
3Circuit fuse check
1) With ignition switch turn OFF, check “A/B” fuse for
blowing.
Is “A/B” fuse in good condition?Go to Step 4. Repair defective wire
circuit. After repaired,
replace “A/B” fuse.

Inspection of Intermittent and Poor
Connections
S6RW0D8204047
Most intermittents are caused by faulty electrical
connections or wiring. When a check for proper
connection is requested in a diagnostic flow, perform
careful check of suspect circuits.
If any abnormality is found, repair or replace as a wire
harness assembly.
• Poor mating of connector halves, or terminals not fully
seated in the connector body (backed out).• Dirt or corrosion on the terminals. The terminals must
be clean and free of any foreign material which could
impede proper terminal contact.
However, cleaning the terminal with a sand paper or
the like is prohibited.
• Damaged connector body, exposing the terminals to
moisture and dirt, as well as not maintaining proper
terminal orientation with the component or mating
connector. 4Contact coil circuit (horn, audio control and cruise
control switch circuit) check (cruise control model)
1) Check for continuity between each terminal of horn
switch terminals, audio control switch terminals and
cruise control switch terminals as shown in figure.
Is each measured resistance 3
Ω or less?Go to Step 5. Replace contact coil.
5Contact coil circuit check
1) Measure resistance between each terminal and other
terminal.
Is each measured resistance infinity?Contact coil and its
circuit are good
condition.Replace contact coil. Step Action Yes No

• Improperly formed or damaged terminals.
Check each connector terminal in problem circuits
carefully to ensure good contact tension by using the
corresponding mating terminal included in the
connector test adapter kit (special tool).
If contact tension is not enough, reform the terminal to
increase contact tension or replace it.
Special tool
(A): 09932–76010 Connector test adapter kit
• Poor terminal-to-wire connection.
Check each wire harness in problem circuits for poor
connection by shaking it by hand lightly. If any
abnormal condition is found, change the wire harness
assembly or component parts with new ones.
• Wire insulation which is rubbed through, causing an
intermittent short as the bare area touches other
wiring or parts of the vehicle.
• Wire broken inside the insulation. This condition could
cause a continuity check to show a good circuit, but if
only 1 or 2 strands of a multi-strand-type wire are
intact, resistance could be far too high.
Repair and Inspection Required after AccidentS6RW0D8204048
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 impact-sensor
– Driver / Passenger side impact-sensors
–SDM
– Contact coil and combination switch
assembly
– Air bag wire harness in main harness,
instrument panel harness, floor harness,
passenger air bag harness, side-air bag
harness and side curtain-air bag
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.

– Check connector or lead wire of SDM for scorching,
melting or damage.
– Check SDM connector and terminals for tightness.
– Check if SDM sets a DTC and is judged as
malfunctioning according to the diagnostic flow.
• Air bag wire harness and connections
– Check for damages, deformities or poor
connections.
Refer to “Inspection of Intermittent and Poor
Connections”.
– Check wire harness clamps for tightness.
• Forward impact-sensor
– Check sensor (1) and apron-side-member (driver
side) (2) for damage, bend or rust.
– Check connector (3) or lead wire (4) of forward-
sensor for scorching, melting or damage.• Side impact-sensor
– Check sensor (1) and under body (2) for dents,
cracks, deformation or rust.
– Check sensor connector (sensor side and harness
side) (3) or sensor lead wire (4) for damage, crack,
scorching or melting.
• Seat belt pretensioner
– Check for dents, cracks, damage or fitness
– Check harness and connector for damage or
tightness.
• Seat belts and mounting points
– Refer to “Front Seat Belt Components in Section
8A”.
• “AIR BAG” warning light
– After vehicle is completely repaired, perform “Air
Bag Diagnostic System Check”.
• Side-air bag (inflator) module
– Check for dents, cracks, damage or fitness.
– Check trim cover for cracks or deformities.
– Check wire harness and connector for damage or
tightness.
• Side curtain-air bag (inflator) module
– Check for dents, cracks, damage or fitness.
– Check harness wire harness and connector for
damage or tightness.
– Check headlining for cracks or deformation.

Air Bag (Inflator) Module and Seat Belt
Pretensioner Disposal
S6RW0D8206018
WARNING!
Failure to follow proper air bag (inflator)
module and seat belt pretensioner disposal
procedures can result in air bag deployment
and pretensioner activation which may cause
personal injury. Do not dispose of live
(undeployed) air bag (inflator) modules and
seat belt pretensioners. Because undeployed
air bag (inflator) module / inactivated seat
belt pretensioner must not be disposed of
through normal refuse channels. Undeployed
air bag (inflator) module and inactivated seat
belt pretensioner contain substances that
can cause severe illness or personal injury if
sealed container is damaged during disposal.

Air bag (inflator) module / seat belt pretensioner can be
deployed / activated inside or outside of vehicle.
Deployment / Activation method used depends upon
final disposition of vehicle. Review the following
instructions in order to determine which will work best in
a given situation.
Deployment / Activation Outside of Vehicle: When you
intend to return the vehicle to service, deploy the air bag
(inflator) module(s) and/or activate seat belt
pretensioner(s) outside of the vehicle.
Deployment / Activation Inside of Vehicle: When the
vehicle will be destroyed, or salvaged for component
parts, deploy the air bag module(s) and/or activate seat
belt pretensioner(s) installed on vehicle.
WARNING!
The following precautions must be observed
for this work. Failure to observe any of them
may result in personal injury.
• Procedure should be followed strictly as
described here.
• Be sure to read “Precautions on Service
and Diagnosis of Air Bag System”
beforehand.
• To avoid accidental deployment /
activation, this work should be performed
by no more than one person.
• Since smoke is produced when air bag
(inflator) module is deployed and
pretensioner is activated, select well-
ventilated area.
• Air bag (inflator) module and seat belt
pretensioner will immediately deploy /
activate when 12 volts vehicle battery is
connected to it. Wear safety glasses
throughout this entire deployment /
activation and disposal procedure.
• Wear suitable ear protection when
deploying air bag (inflator) module /
activating seat belt pretensioner. Also,
advise those who are in area close to
deployment / activation site to wear
suitable ear protection.
• Do not deploy / activate two or more air
bag system components (air bag (inflator)
modules and seat belt pretensioners) at
the same time.
• Never connect deployment harness to any
12 volts vehicle battery before connecting
deployment harness to air bag (inflator)
module and seat belt pretensioner.
Deployment harness shall remain shorted
and not be connected to 12 volts vehicle
battery till you are ready to deploy air bag
(inflator) module or activate seat belt
pretensioner.
