INSPECTION
Valve guides
Using a micrometer and bore gauge, take diameter readings on
valve stems and guides to check stem-to-guide clearance. Be
sure to take reading at more than one place along the length of
each stem and guide.
If clearance exceeds limit, replace valve and valve guide.
Valve stem-to-guide clearance :

Rectifier
•Positive Rectifier
a) Using an ohmmeter, connect one tester probe to the “B”
terminal (1) and the other to each rectifier terminal (2).
b) Reverse the polarity of the tester probes and repeat step a).
c) Check that one shows continuity and the other shows no
continuity. If there is continuity, replace the rectifier.
•Negative Rectifier
a) Using an ohmmeter, connect one tester probe to each neg-
ative terminal (1) and the other to each rectifier terminal (2).
b) Reverse the polarity of the tester probes and repeat step a).
c) Check that one shows continuity and the other shows no
continuity. If there is continuity, replace the rectifier.

AIR BAG SYSTEM 10B-57
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.
Those components are:
•Steering column and shaft joints
–Check for length, damage and bend according to “CHECK-
ING STEERING COLUMN FOR ACCIDENT DAMAGE” in
Section 3C1.
•Steering column bracket and capsules
–Check for damage and bent.
•If any faulty condition is found in above checks, replace faulty
part.
•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.
•If any faulty condition is found in above checks, replace faulty
part.
•Contact coil and combination switch assembly
–Check wire harness and connectors for damage or tight-
ness.
–Check contact coil case for damage.
•If any faulty condition is found in above checks, replace.

AIR BAG SYSTEM 10B-69
6) Stretch the deployment harness from the driver or passenger
air bag (inflator) module to its full length 10 m (33 ft) (1).
Special tool
(A) : 09932-75030
7) Place a power source (3) near the shorted end of the deploy-
ment harness. Recommended application: 12 Volts mini-
mum, 2 amps minimum. A vehicle battery is suggested.
8) Verify that the area around the air bag (inflator) module or
seat belt pretensioner is clear of all people and loose or flam-
mable objects.
9) Verify setting condition of air bag (inflator) module or preten-
sioner as follows.
[In case of driver air bag (inflater) module]
Verify that the driver air bag (inflator) module is resting with
its vinyl trim cover facing up.
[In case of passenger air bag (inflator) module]
Verify that the passenger air bag (inflator) module is firmly
and properly secured in passenger air bag (inflator) module
deployment fixture (special tool).
[In case of seat belt pretensioner]
Verify that the seat belt pretensioner, is placed as shown in
the figure on the ground in the space just cleared.
10) Connect (2) the air bag (inflator) module or seat belt preten-
sioner to the deployment harness connector and lock con-
nector with lock lever.
11) Notify all people in the immediate area that you intend to
deploy/activate the air bag (inflator) module or seat belt pre-
tensioner.
[A] : For Driver Air Bag (Inflator) Module
[B] : For Passenger Air Bag (Inflator) Module
[C] : For Seat Belt Pretensioner
NOTE:
When the air bag deploys and the pretensioner acti-
vates, the rapid gas expansion will create a substantial
report. Wear suitable ear protection. Notify all people
in the immediate area that you intend to deploy the air
bag (inflator) module or activate the seat belt preten-
sioner and suitable ear protection should be worn.
When the driver air bag deploys and the pretensioner
activates, driver air bag (inflator) module and preten-
sioner (retractor assembly) may jump about 30 cm (1
ft) vertically. This is a normal reaction of them to the
force of the rapid gas expansion inside the air bag and
pretensioner.
After the air bag (inflator) module has been deployed,
the surface of the air bag may contain a powdery resi-
due. This powder consists primarily of cornstarch
(used to lubricate the bag as it inflates) and by-prod-
ucts of the chemical reaction.
