Maintenance Items
CAUTION:
Do not use a circuit tester to check SRS circuit.
1. Check operation of ``AIR BAG'' warning lamp.
After turning ignition key to ``ON'' position, both warning lamps
illuminate. The ``AIR BAG'' warning lamp will go off after about
7 seconds if no malfunction is detected.
If any of the following warning lamp conditions occur, immedi-
ately check the air bag or seat belt pre-tensioner system. Refer
to RS-30 for details.
+The ``AIR BAG'' warning lamp does not illuminate when the
ignition switch is turned ``ON''.
+The ``AIR BAG'' warning lamp does not go off about 7 seconds
after the ignition switch is turned ``ON''.
+The ``AIR BAG'' warning lamp blinks about 7 seconds after the
ignition switch is turned ``ON''.
2. Visually check SRS components.
(1) Diagnosis sensor unit
+Check diagnosis sensor unit and bracket for dents, cracks or
deformities.
+Check connectors for damage, and terminals for deformities.
(2) Air bag module and steering wheel
+Remove air bag module from steering wheel or instrument
panel. Check harness cover and connectors for damage, ter-
minals for deformities, and harness for binding.
+Install driver air bag module to steering wheel to check ®t or
alignment with the wheel.
+Check steering wheel for excessive free play.
+For dual air bag system, install passenger air bag module to
instrument panel to check ®t or alignment with the instrument
panel.
(3) Spiral cable
+Check spiral cable for dents, cracks, or deformities.
+Check connectors and protective tape for damage.
+Check steering wheel for noise, binding or heavy operation.
(4) Harness related to SRS
+Check connectors for poor connections, damage, and terminals
for deformities.
+Check harnesses for binding, cha®ng or cut.
(5) Seat belt pre-tensioner
+Check harness cover and connectors for damage, terminals for
deformities, and harness for binding.
+Check belts for damage and anchors for loose mounting.
+Check retractor for smooth operation.
+Perform self-diagnosis for seat belt pre-tensioner using
bulb or CONSULT. Refer to ``SRS Operation Check'' for details.
(RS-30)
CAUTION:
Replace previously used special bolts, ground bolt and anchor
bolt with new ones.

HOW TO ERASE SELF-DIAGNOSIS RESULTS
With CONSULT
+``SELF-DIAG [CURRENT]''
A current Self-diagnosis result is displayed on the CONSULT screen in real time. After the malfunction is
repaired completely, no malfunction is detected on ``SELF-DIAG [CURRENT]''.
+``SELF-DIAG [PAST]''
Return to the ``SELF-DIAG [CURRENT]'' CONSULT screen by
pushing ``BACK'' key of CONSULT and select ``SELF-DIAG
[CURRENT]'' in ``SELECT DIAG MODE''. Touch ``ERASE'' in
``SELF-DIAG [CURRENT]'' mode.
NOTE:
If the memory of the malfunction in ``SELF-DIAG [PAST]'' is not
erased, the User mode shows the system malfunction by the
operation of the warning lamp even if the malfunction is
repaired completely.
+``TROUBLE DIAG RECORD''
The memory of ``TROUBLE DIAG RECORD'' cannot be erased.
Without CONSULT
After a malfunction is repaired, return to User mode from Diagnosis mode by switching the ignition ``OFF'' for
at least 1 second, then back ``ON''. At that time, the problem code is cleared.
How to Perform Trouble Diagnoses for Quick
and Accurate Repair
A good understanding of the malfunction conditions can make troubleshooting faster and more accurate.
In general, each customer feels differently about a problem. It is important to fully understand the symptoms
or conditions for a customer complaint.
