Trouble Diagnosis: “AIR BAG” Warning Lamp Does Not Turn OFFBHS0004C
DIAGNOSTIC PROCEDURE 7
1. CHECK THE DEPLOYMENT OF AIR BAG MODULE
Is air bag module deployed?
YES or NO
YES >> Refer to SRS-55, "COLLISION DIAGNOSIS" .
NO >> GO TO 2.
2. CHECK THE AIR BAG FUSE
Check 10A fuse [No.13, located in fuse block (J/B)].
Refer to PG-3, "
POWER SUPPLY ROUTING CIRCUIT" .
OK or NG
OK >> GO TO 4.
NG >> GO TO 3.
3. CHECK AIR BAG FUSE AGAIN
Replace “AIR BAG” fuse and turn ignition switch ON.
Does the
“AIR BAG” fuse blow again?
YES >> Repair or replace main harness.
NO >>INSPECTION END
4. CHECK DIAGNOSIS SENSOR UNIT
Connect CONSULT-II and touch “START”.
Is
“AIR BAG” displayed on CONSULT-ll?
YES >> GO TO 5.
NO >> Visually check the wiring harness connection of diagno-
sis sensor unit. If the harness connection check result is
OK, replace diagnosis sensor unit.
5. CHECK HARNESS CONNECTION
Is harness connection between warning lamp and diagnosis sensor unit OK?
OK or NG
OK >> Replace diagnosis sensor unit.
NG >> Connect “AIR BAG” warning lamp and diagnosis sensor unit connector properly. If “AIR BAG”
warning lamp still does not go off, replace harness.
