Whether or not the air bags have
deployed, check and service the vehicle after collision as
follows:
|

|
1.
caution |
Refer to that the ignition
switch is "LOCK" (OFF) when connecting or
disconnecting M.U.T.-III.
|
Connect the M.U.T.-III to the diagnosis connector
(Refer to GROUP 00, How to Use
Troubleshooting/Inspection Service Points ). 2.Read
(and write down) all displayed diagnosis codes (Refer to
<Except vehicles for Hong Kong, Singapore,Australia
and New Zealand>,
<Vehicles for Hong Kong and Singapore> or
<Vehicles for Australia and New Zealand>
).
note |
If battery power supply has
been shut down by the collision, the M.U.T.-III
cannot communicate with the SRS-ECU. Check and,
repair if necessary, the instrument panel wiring
harness before the next job.
|
3.Use the M.U.T.-III to read the data list
(how long trouble(s) have continued and how often memory
have been erased).

4.Erase the diagnosis codes and after waiting
5 seconds or more read (and write down) all displayed
diagnosis codes.
|
|
1.Replace the following
parts with new ones.
- SRS-ECU (Refer to
<Except vehicles for Hong Kong and
Singapore> or
<vehicles for Hong Kong and
Singapore>).
- Front air bag modules (Refer to
).
- Seat belt with pre-tensioner (Refer to
).

<Except vehicles for Hong Kong and
Singapore> or
<vehicles for Hong Kong and
Singapore>).

Panel Assembly
).
|
|
2.Check the following parts
and replace if there are any
malfunctions.
- Clock spring (Refer to
).
- Steering wheel, steering column and shaft assembly
(Refer to GROUP 37, Steering wheel
,
Steering column and 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 or alignment with
the steering wheel. (3)
Check the steering wheel for noise, binds or difficult
operation and excessive free play. (4)
Check the steering column shaft shock absorbing mechanism
(Refer to GROUP 37, On-Vehicle Service ).
|
|
3.Check the harness for
binding, connectors for damage, poor connections, and
terminals for deformation (Refer to ).
|
|
1.Replace the following
parts with new ones.
- SRS-ECU (Refer to
<Except vehicles for Hong Kong and
Singapore> or
<vehicles for Hong Kong and
Singapore>).
- Side impact sensors (Refer to
).
- Curtain air bag modules (Refer to
).
- Front seat assembly (Refer to GROUP 52A, Front Seat
Assembly
).
|
|
2.Check the harness for
binding, connectors for damage, poor connections, and
terminals for deformation (Refer to ).
|
|
Check the SRS components. If
visible damage such as dents, cracks, or deformation are
found on the SRS components, replace them with new ones.
Concerning parts removed for inspection, replacement with
new parts and cautions in working, refer to ![](../../../buttons/03btn007.png)
|

|
1.Check the front side
member and front impact sensor for deformation or
rust. 2.Check the front impact sensor for dents,
cracks, deformation or rust. 3.Check the sensor
harnesses for binding, the connectors for damage, and the
terminals for deformation.
note |
The figures show front impact
sensors (LH). The side impact sensors (RH) is
symmetrical with the side impact sensors
(LH).
