Maintenance Items
CAUTION:
Do not use electrical test equipment to check SRS circuit.
1. Check operation of ªAIR BAGº warning lamp.
After turning ignition key to ªONº position, the ªAIR BAGº
warning lamp illuminates. The ªAIR BAGº warning lamp will
go off after about 7 seconds if no malfunction is detected.
If any of the following warning lamp conditions occur, imme-
diately check the air bag system. Refer to ªSRS-Operation
Checkº for details. (RS-37)
lThe ªAIR BAGº warning lamp does not come on when the
ignition switch is turned ªONº.
lThe ªAIR BAGº warning lamp does not go off about 7 sec-
onds after the ignition switch is turned ªONº.
lThe ªAIR BAGº warning lamp blinks about 7 seconds after
the ignition switch is turned ªONº.
2. Visually check SRS components.
(1) Diagnosis sensor unit
lCheck diagnosis sensor unit and bracket for dents, cracks or
deformities.
lCheck connectors for damage, and terminals for deformities.
(2) Air bag module and steering wheel
lRemove air bag module from steering wheel, instrument
panel or seat back. Check harness cover and connectors for
damage, terminals for deformities, and harness for binding.
lInstall driver's air bag module to steering wheel to check fit
or alignment with the wheel.
lCheck steering wheel for excessive free play.
lInstall passenger's air bag module to instrument panel to
check fit or alignment with the instrument panel.
lInstall side air bag module to seatback to check fit and align-
ment with the seat.
(3) Spiral cable
lCheck spiral cable for dents, cracks, or deformities.
lCheck connectors and protective tape for damage.
lCheck steering wheel for noise, binding or heavy operation.
(4) Main harness, body harness and air bag harness
lCheck connectors for poor connections, damage, and termi-
nals for deformities.
lCheck harnesses for binding, chafing or cuts.
(5) Seat belt pre-tensioner
lCheck harness cover and connectors for damage, terminals
for deformities, and harness for binding.
lCheck belts for damage and anchors for loose mounting.
lCheck retractor for smooth operation.
lPerform self-diagnosis for seat belt pre-tensioner using ªAIR
BAGº warning lamp or CONSULT-II. Refer to ªSRS Operation
Checkº for details. (RS-37)
(6) Side airbag (Satellite) sensor
lCheck Side airbag (Satellite) sensor (including bracket por-
tion) for dents, cracks or deformities.
lCheck connectors for damage, and terminals for deformities.

HOW TO CHANGE SELF-DIAGNOSIS MODE
With CONSULT-II
From User mode to Diagnosis mode
After selecting AIR BAG on the ªSELECT SYSTEMº screen, User mode automatically changes to Diagno-
sis mode.
From Diagnosis mode to User mode
To return to User mode from diagnosis mode, touch ªBACKº key of CONSULT-II until ªSELECT SYSTEMº
appears. Diagnosis mode automatically changes to User mode.
How to Change Self-diagnosis Mode without CONSULT-II
From User Mode to Diagnosis Mode
Diagnosis mode activates only when a malfunction is detected, by turning ignition switch as follows:
1) Turn ignition switch ªONº.
2) After ªAIR BAGº warning lamp lights for 7 seconds, turn ignition switch ªOFFº within 1 second.
3) Wait more than 3 seconds.
4) Repeat steps 1 to 3 three times.
5) Turn ignition switch ªONº.
SRS will not enter Diagnosis mode, if no malfunction is detected.
From Diagnosis Mode to User Mode
After a malfunction is repaired, switch the ignition ªOFFº for at least one second, then back ªONº. Diagno-
sis mode is returned to User mode.
If switching Diagnosis mode to User mode is required while malfunction is being detected, by turning igni-
tion switch as follows:
1) Turn ignition switch ªONº.
2) After ªAIR BAGº warning lamp lights for 7 seconds, turn ignition switch ªOFFº within 1 second.
3) Wait more than 3 seconds.
4) Repeat steps 1 to 3 three times.
5) Turn ignition switch ªONº.
