1.CHECK CONDITION OF AIR BAG MODULE
Inspect for any deployed air bag modules or seat belt pre-tensioners.
Are any air bag modules or seat belt pre-tensioners deployed?
Yes >> Refer to SRS-46.
No >> GO TO 2.
2.CHECK THE AIR BAG FUSE
Check 10A fuse [No. 1, located in the fuse block (J/B)].
Refer to PG-3
.
OK or NG
OK >> GO TO 4.
NG >> GO TO 3.
3.CHECK AIR BAG FUSE AGAIN
Replace 10A fuse [No. 1, located in the fuse block (J/B)] and turn ignition switch ON.
Does the fuse blow again?
Yes >> Repair harness.
No >> Inspection End.
4.CHECK AIR BAG DIAGNOSIS SENSOR UNIT
Connect CONSULT-III and touch “START”.
Is
“AIR BAG” displayed on CONSULT-III?
Yes >> GO TO 5.
No >> Visually inspect the air bag diagnosis sensor unit harness connections. If the connections are OK,
replace the air bag diagnosis sensor unit. Refer to SRS-44, "
Removal and Installation".
5.CHECK HARNESS CONNECTION
Check for loose connections between the combination meter and the air bag diagnosis sensor unit.
OK or NG
OK >> Replace air bag diagnosis sensor unit. Refer to SRS-44, "Removal and Installation".
NG >> Properly connect the combination meter and air bag diagnosis sensor unit harness connectors. If
“AIR BAG” warning lamp still does not turn off, replace the wiring harness.
