stored in memory.
2) Select trouble code required to check airbag compo-
nent parts from those listed in table and reproduce symp-
tom.

2. AIRBAG COMPONENT PARTS APPEARANCE
INSPECTION
Conduct appearance inspection on parts selected.
NOTE:
Also check connector terminals, wiring harness, case, etc.
for damage.
3. AIRBAG COMPONENT PARTS VIBRATION
INSPECTION
1) Gently shake check parts (to determine faults.).
2) To check airbag module or roll connector, turn and tilt
steering wheel.
CAUTION:
Do not shake or vibrate airbag control module and
front sensor at the same time as erroneous operation
may result.

4. SHOWERING INSPECTION TO BODY
1) Spray water on vehicle body.
CAUTION:
Do not directly spray water on airbag components.
2) Check passenger compartment for traces of leaking.
NOTE:
Also check wiring harnesses as water may leak along them
and get airbag component parts wet.
