Precautions for SRS ªAIR BAGº and ªSEAT
BELT PRE-TENSIONERº Service
+Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
+Before servicing the SRS, turn ignition switch ªOFFº, disconnect both battery cables and wait at least 3
minutes.
For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt
pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes
have passed.
+Diagnosis sensor unit must always be installed with their arrow marks ª
Sº pointing towards the front of
the vehicle for proper operation. Also check diagnosis sensor unit for cracks, deformities or rust before
installation and replace as required.
+The spiral cable must be aligned with the neutral position since its rotations are limited. Do not attempt
to turn steering wheel or column after removal of steering gear.
+Handle air bag module carefully. Always place driver and passenger air bag modules with the pad side
facing upward and front side air bag modules (built-in type) with the stud bolt side facing down.
+Conduct self-diagnosis to check entire SRS for proper function after replacing any components.
+After air bag inflates, the front instrument panel assembly should be replaced if damaged.

Removal and Installation Ð Diagnosis
Sensor Unit, Seat Belt Pre-tensioner with
Load Limiter
CAUTION:
+Before servicing SRS, turn the ignition switch off, disconnect both battery cables and wait at least
3 minutes.
+Do not use old bolts and nuts coated with bonding agent after removal; replace with new ones.
+Check diagnosis sensor unit, seat belt pre-tensioner with load limiter and satellite sensor for
proper installation.
+Check diagnosis sensor unit and satellite sensor to ensure they are free of deformities, dents,
cracks or rust. If they show any visible signs of damage, replace them with new ones.
+Check diagnosis sensor unit brackets to ensure they are free of deformities and rust.
+After replacement of diagnosis sensor unit, seat belt pre-tensioner and satellite sensor, check
SRS function and perform self-diagnosis for SRS. Refer to ªSelf-diagnosisº for details.
+Do not attempt to disassemble diagnosis sensor unit, seat belt pre-tensioner with load limiter and
satellite sensor.
+Replace diagnosis sensor unit, seat belt pre-tensioner and satellite sensor if it has been dropped
or sustained an impact.
+Do not expose seat belt pre-tensioner to temperatures exceeding 80ÉC (176ÉF).
REMOVAL OF DIAGNOSIS SENSOR UNIT
1. Disconnect driver, passenger and side air bag module con-
nectors. Also, disconnect seat belt pre-tensioner connector.
2. Remove console finisher, console box assembly and instru-
ment panel stay cover. Refer to ªINSTRUMENT PANELº in
BT section.
3. Disconnect diagnosis sensor unit connector.
4. Remove bolt and diagnosis sensor unit fixing bolts.
Then remove the diagnosis sensor unit.
NOTE:
+To install, reverse the removal procedure sequence.
+After replacement, perform self-diagnosis for SRS. Refer
to ªSelf-diagnosisº for details.
CAUTION:
Do not use old special bolts coated with bonding agent;
replace with new coated special bolts.

Removal Ð Driver Air Bag Module and Spiral
Cable
CAUTION:
+Before servicing SRS, turn the ignition switch OFF, dis-
connect both battery cables and wait at least 3 minutes.
+Always work from the side of air bag module.
1. Remove lower lid from steering wheel, and disconnect air
bag module connector.
2. Remove side lid, ASCD steering switch and audio steering
switch. Using the TAMPER RESISTANT TORX (Size T30),
remove left and right special bolts. Air bag module can then
be removed.
CAUTION:
+Always place air bag module with pad side facing
upward.
+Do not attempt to disassemble air bag module.
+The special bolts are coated with bonding agent. Do not
use old bolts after removal; replace with new ones.
+Do not insert any foreign objects (screwdriver, etc.) into
air bag module connector.

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 igni-
tion 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.

HOW TO ERASE SELF-DIAGNOSIS RESULTS
With CONSULT-II
+ªSELF-DIAG [CURRENT]º
A current Self-diagnosis result is displayed on the CON-
SULT-II screen in real time. After the malfunction is repaired
completely, no malfunction is detected on ªSELF-DIAG
[CURRENT]º.
+ªSELF-DIAG [PAST]º
Return to the ªSELF-DIAG [CURRENT]º CONSULT-II screen
by pushing ªBACKº key of CONSULT-II and select ªSELF-
DIAG [CURRENT]º in ªSELECT DIAG MODEº. Touch
ªERASEº in ªSELF-DIAG [CURRENT]º mode.
NOTE:
If the memory of the malfunction in ªSELF-DIAG [PAST]º is
not erased, the User mode shows the system malfunction by
the operation of the warning lamp even if the malfunction is
repaired completely.
+ªTROUBLE DIAG RECORDº
The memory of ªTROUBLE DIAG RECORDº cannot be
erased.
Without CONSULT-II
After a malfunction is repaired, return Diagnosis mode to User
mode by switching the ignition ªOFFº for at least 1 second, then
back ªONº. At that time, the self-diagnostic result 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 malfunction. It is important to fully understand the symp-
toms or conditions for a customer complaint.
INFORMATION FROM CUSTOMER
WHAT ........ Vehicle model
WHEN ....... Date, Frequencies
WHERE ..... Road conditions
HOW .......... Operating conditions, Symptoms
PRELIMINARY CHECK
Check that the following parts are in good order.
