B: INSPECTION
1) Make sure the condenser fins are free from dust and
insects. If the fins are clogged, clean by blowing air or
water through them.
NOTE:
To prevent dust and water from getting into the condenser,
this work must be done when the condenser is installed in
an actual vehicle.
2) Check the condenser to see if it shows any sign of oil.
Should oil ooze or gas leak from the condenser replace it
with a new one.

2 MaskingMask specified part (black base) with masking tape. Use masking tape for PP (e.g., Nichiban No.
533, etc.).
3Degreasing, clean-
ingClean all parts to be painted with white gasoline, normal alcohol, etc. to remove dirt, oil, fat, etc.
4 Primer paint First, apply one coat of primer to all parts to be painted, using air gun. Use primer (clear).
5 DryingDry at normal temperature [10 to 15 min. at 20°C (68°F)].
In half-dried condition, PP primer paint is dissolved by solvent, e.g. thinner, etc.
Therefore, if dust or dirt must be removed, use ordinary alcohol, etc.

2. Inspection and Replacement
Standards
1. VEHICLES WHICH BECOME INVOLVED IN A
COLLISION
If the vehicle equipped with an SRS airbag system is
damaged in a collision, the airbag system parts must
be checked and replaced in accordance with the fol-
lowing standards:
After faulty parts are replaced, the warning light opera-
tion must be checked.
When the ignition switch is turned ON, it lights up
for 8 seconds and then it goes out for at least 30 sec-
onds.
The trouble code stored in memory must be erased
after the check.
2. AIRBAG MODULE (DRIVER AND PASSENGER)
Inspection standard:
The vehicle damaged in a collision (regardless of
whether or not airbag is deployed).
The designated trouble code is output during self-diag-
nosis. (Refer to“Diagnostics”Section.)
Replacement standard:
Airbag is deployed.
The pad surface is scratched or cracked.
Harness and/or connector is deformed or cracked, their
circuits are broken, lead wire is exposed, etc.
Mounting bracket is cracked or deformed.
The module surface is fouled with foreign matter.
(grease, oil, water, cleaning solvent, etc.)
Airbag module dropped to the floor/ground.
Airbag module determined as faulty during self-diagno-
sis.

CAUTION:
The airbag module (driver side and passenger side)
must not be disassembled. The airbag module cannot
be used again once inflated.
G5M0300
When removing and installing the airbag module
(driver side and passenger side), the operator should
stand, as much as possible, on the side of the airbag
module.
G5M0301
After removal, the airbag module (driver side and
passenger side) should be kept away from heat and
light sources, and stored on a clean, flat surface to
prevent from any damage to its lower structure.
G5M0302
Do not check airbag module (driver side and pas-
senger side) continuity with airbag removed from the
vehicle body.
Replace airbag module (driver side and passenger
side) with a new one, should any of the following con-
ditions develop.
(1) Pad surface is scratched or cracked.
(2) Connector harness is damaged.
(3) Inflator side structure of module is cracked or
deformed.
