TROUBLE DIAGNOSIS
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.

DIAGNOSTIC PROCEDURE 8
1.CHECK METER FUSE
Check the 10A fuse [No. 14, located in the fuse block (J/B)].
Refer toPG-4, "
POWER SUPPLY ROUTING CIRCUIT".
OK or NG
OK >> GO TO 3.
NG >> GO TO 2.
2.CHECK METER FUSE AGAIN
Replace 10A fuse [No. 14, located in the fuse block (J/B)] and turn ignition switch ON.
Does the fuse blow again?
Yes >> Repair or replace the related harness.
No >> Inspection End.
3.CHECK HARNESS CONNECTION BETWEEN AIR BAG DIAGNOSIS SENSOR UNIT AND COMBINA-
TION METER
Disconnect the air bag diagnosis sensor unit harness connectors and turn ignition switch ON.
Does
“AIR BAG”warninglampturnON?
Yes >> Replace the air bag diagnosis sensor unit. Refer toSRS-48, "Removal and Installation".
No >> Check the combination meter power supply circuits and ground circuits. If OK, replace combina-
tion meter.

5. Disconnect lighting and turn signal switch connector. Then while
pressing tabs, pull lighting and turn signal switch toward driver
door to remove.
6. Remove the screws. Then while pressing the tab, pull the spiral
cable away from steering column assembly.
CAUTION:
lDo not disassemble spiral cable.
lDo not apply lubricant to the spiral cable.
7. Disconnect the spiral cable connectors.
CAUTION:
With the steering linkage disconnected, the spiral cable
may snap by turning the steering wheel beyond the limited
number of turns. The spiral cable can be turned counter-
clockwise about 2.5 turns from the right end position.
INSTALLATION
Install in the reverse order of removal.
lAlign spiral cable correctly when installing steering wheel, refer
toSRS-39, "
INSTALLATION". Make sure that the spiral cable is
in the neutral position. The neutral position is detected by turn-
ing left 2.6 revolutions from the right end position and ending
with the locating pin at the top.
lReset the steering angle sensor calibration after installing spiral
cable.
lAfter the work is completed, perform self-diagnosis to make sure
no malfunction is detected. Refer toSRS-18, "
SRS Operation
Check".
CAUTION:
lThe spiral cable may snap due to steering operation if the
cable is not installed in the correct position.
lWith the steering linkage disconnected, the cable may snap by turning the steering wheel beyond
the limited number of turns. The spiral cable can be turned counterclockwise about 2.5 turns from
the right end position.
