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 ªSº 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.

FOR SIDE COLLISION
To repair the SRS for a side collision, perform the following steps.
When the built-in type front side air bag is activated in the side collision:
V1Replace the following components:
- All parts of front seat back with side air bag modules (on the side on which side air bag is activated)
- Diagnosis sensor unit
- Satellite sensor (on the side on which side air bag is activated)
V2Check the SRS components and the related parts using the table shown below.
+Replace any SRS components and the related parts showing visible signs of damage (dents, cracks,
deformation).
V3Conduct self-diagnosis using CONSULT-II, and ªAIR BAGº warning lamp and ªSEAT BELTº warning
lamp (Models except for Europe). Refer to ªSelf-diagnosisº for details (RS-1032). Ensure entire SRS
operates properly.
When SRS is not activated in the side collision:
V1Check the SRS components and the related parts using the table shown below.
+Replace any SRS components and the related parts showing visible signs of damage (dents, cracks,
deformation).
V2Conduct self-diagnosis using CONSULT-II, ªAIR BAGº warning lamp and ªSEAT BELTº warning lamp
(Models except for Europe). Refer to ªSelf-diagnosisº for details (RS-1032). Ensure entire SRS operates
properly.
In the case of the side collision
Part Side air bag is acti-
vatedSRS is NOT activated
Built-in side air bags
module (LH or RH)REPLACE all parts
of front seatback
with deployed side
air bag module.1. Check for visible signs of damage (dents, tears, deformation) of the seatback on
the collision side.
2. If damagedÐREPLACE the damaged seat parts with new bolts and remove the
side air bag module.
3. Check for visible signs of damage (tears etc.) of the side air bag module.
4. Check harness and connectors for damage, and terminals for deformities.
5. If no damage is found, reinstall the side air bag module with new torx nuts coated
with bonding agent.
6. If damagedÐREPLACE the side air bag module with new torx nuts coated with
bonding agent. Air bag must be deployed before disposing of it.
Satellite sensor (LH
or RH)REPLACE the satel-
lite sensor on the
collision side with
new nuts.
(Repair the center
pillar inner, etc.
before installing new
one if damaged.)1. Remove the satellite sensor on the collision side. Check harness connectors for
damage, terminals for deformities, and harness for binding.
2. Check for visible signs of damage (dents, cracks, deformation) of the satellite
sensor.
3. Install the satellite sensor to check fit.
4. If no damage is found, reinstall the satellite sensor with new nuts coated with
bonding agent.
5. If damagedÐREPLACE the satellite sensor with new nuts coated with bonding
agent.
Diagnosis sensor
unitREPLACE the diag-
nosis sensor unit
with the new bolts.1. Check case and bracket for dents, cracks or deformities.
2. Check connectors for damage, and terminals for deformities.
3. If no damage is found, reinstall the diagnosis sensor unit with new special bolts
and ground bolt coated with bonding agent.
4. If damagedÐREPLACE the diagnosis sensor unit with new special bolts and
ground bolt coated with bonding agent.
Seat belt pre-ten-
sioner assembly1. Check if the seat belt can be extended smoothly.
If the seat belt cannot be extended smoothly.
- Check for deformities of the center pillar inner.
- If the center pillar inner has no damage, REPLACE the seat belt pre-tensioner assembly.
2. Remove the seat belt pre-tensioner assembly on the collision side. Check harness cover and connectors
for damage, terminals for deformities, and harness for binding.
3. Check for visible signs of damage (dents, cracks, deformation) of the seat belt pre-tensioner assembly.
4. If no damage is found, reinstall the seat belt pre-tensioner assembly with new bolts coated with bonding
agent.
5. If damagedÐREPLACE the seat belt pre-tensioner assembly with new bolts coated with bonding agent.
The seat belt pre-tensioner assembly must be deployed before disposing of it.
