Trouble Diagnosis: “AIR BAG” Warning Lamp Does Not Turn OFF
EHS001XQ
DIAGNOSTIC PROCEDURE 7
1.CHECK CONDITION OF AIR BAG MODULES
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 toSRS-56, "COLLISION DIAGNOSIS".
No >> GO TO 2.
2.CHECK THE AIR BAG FUSE
Check 10A fuse [No. 13, located in the fuse block (J/B)].
Refer toPG-4, "
POWER SUPPLY ROUTING CIRCUIT".
OK or NG
OK >> GO TO 4.
NG >> GO TO 3.
3.CHECK AIR BAG FUSE AGAIN
Replace 10A fuse [No. 13, located in the fuse block (J/B)] and turn ignition switch ON.
Does the fuse blow again?
Yes >> Repair or replace main harness.
No >> Inspection End.
4.CHECK AIR BAG DIAGNOSIS SENSOR UNIT
Connect CONSULT-II and CONSULT-II CONVERTER and touch
“START”.
Is
“AIR BAG”displayed on CONSULT-II?
Yes >>GOTO5.
No >> Visually inspect the air bag diagnosis sensor unit har-
ness connections. If the connections are OK, replace
the air bag diagnosis sensor unit. Refer toSRS-48,
"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 toSRS-48, "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.
