NO >> Refer to GI-43, "Intermittent Incident"
.
3.WIRING HARNESS
Check the wiring harness for visible damage
NOTE.
NOTE:
The entire wiring harness should be in spected from the air bag diagnosis sensor unit to the end component
(including any in-line connectors).
Is the inspection result normal?
YES >> GO TO 4.
