REPAIR PROCEDURE
.
WHEN FRONT AIR BAGS DEPLOY IN A COLLISION.
1. Replace the following parts with new ones:
• SRS-ECU (Refer to
• Air bag modules (Refer to
• Seat belt with pre-tensioner (Refer to
• Front seat asembly <Passenger’s side> (Refer to GROUP
52A, Front Seat Assembly
• Front impact sensors (Refer to
• Instrument panel (Refer to GROUP 52A, Instrument Panel
Assembly
2. Check the following parts and replace if there are any
malfunctions:
• Clock spring (Refer to
• Seat slide sensor (Refer to
• Seat belt switch (Refer to GROUP 52A, Front Seat Assem-
bly
• Steering wheel, steering column shaft assembly
(1) Check the wiring harness (built into the steering wheel)
and connectors for damage, and terminals for
deformation.
(2) Install the air bag module to check fit and alignment with
the steering wheel.
(3) Check the steering wheel for noise, binding or difficult
operation and excessive free play.
(4) Check the steering column shaft shock absorbing
mechanism (Refer to GROUP 37A, On-Vehicle Service
−
Steering Column Shaft Assembly Shock Absorbing
Mechanism Check
3. Check the wiring harnesses for binding, the connectors for
damage, poor connections, and the terminals for
deformation (Refer to
).
.
WHEN SIDE AIR BAGS DEPLOY IN A COLLISION.
1. Replace the following parts with new ones:
• SRS-ECU (Refer to
• Side impact sensors (Refer to
).
• Front seat assembly (Refer to GROUP 52A, Front Seat
Assembly
2. Check the wiring harnesses for binding, the connectors for
damage, poor connections, and the terminals for
deformation (Refer to
).
.
WHEN AIR BAGS DO NOT DEPLOY IN LOW-SPEED
COLLISION.
Check the SRS components. If the SRS components are show-
ing any visible damage such as dents, cracks, or deformation,
replace them with new ones. Concerning parts removed for
inspection, replacement with new parts and cautionary points
for working, refer to appropriate INDIVIDUAL COMPONENT
SERVICE
