INFOID:0000000006211125
DIAGNOSTIC PROCEDURE 7
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 s eat belt pre-tensioners deployed?
Yes >> Refer to SRS-48, "For Frontal Collision" or SRS-50, "For Side and Rollover Collision".
No >> GO TO 2.
2.CHECK THE AIR BAG FUSE
Check 10A fuse [No. 1, locat ed in the fuse block (J/B)].
Refer to SRS-11, "
Schematic".
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 fu se 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?
Ye s > > G O T O 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-45, "
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-45, "Removal and Installation".
NG >> Properly connect the combination meter and ai r bag diagnosis sensor unit harness connectors. If
“AIR BAG” warning lamp still does not turn off, replace the wiring harness.

REMOVAL
WARNING:
Before disconnecting diagnosis sensor unit harness connector(s), be sure to disconnect harness con-
nectors from air bag modules and front seat belt pre-tensioner to prevent deployment by static elec-
tricity.
CAUTION:
• Before servicing the SRS, turn th e ignition switch OFF, disconnect both battery terminals and wait at
least three minutes.
• Do not disassemble diagnosis sensor unit.
• Do not use old bolts; replace with new bolts.
• Replace the diagnosis sensor unit if it has been dropped or sustained an impact.
• Check diagnosis sensor unit bracket to make sure it is free of deformities, dents, cracks or rust. If it
shows any visible signs of da mage, replace with new one.
• The diagnosis sensor unit must always be installed with the arrow mark " ⇐" pointing toward the
front of the vehicle for proper operation.
• When replacing the air bag diagno sis sensor unit, always check with the parts department for he lat-
est parts information. Installing an incorrect air bag diagnosis sensor unit may or may not cause the
air bag warning lamp to illuminate and may cause incorrect deployment of the supplemental air bags
and seat belt pre-tensioner in a collision r esulting in serious personal injury or death.
1. Always check the air bag diagnosis sensor unit E CU discriminated number (identification number) using
CONSULT-III.
2. Disconnect the negative and positive battery term inals, then wait at least three minutes.
3. Disconnect the harness connectors for the following SRS components: Refer to SRS-40
(Side Curtain Air
Bag Module), SRS-44
(Front Seat Belt Pre-tensioner), SE-13, "Disassembly and Assembly" (Side Air Bag
Module).
4. Remove center console assembly. Refer to IP-11
.
5. Disconnect diagnosis sensor unit connectors.
6. Remove the bolts and the ground bolt, then remove the diagnosis sensor unit.
INSTALLATION
Installation is in the reverse order of removal.
• The diagnosis sensor unit must always be installed with the arrow mark " ⇐" pointing toward the front of the
vehicle.
• Follow the tightening sequence 1,2,3,4 as shown.
