POST-COLLISION DIAGNOSIS
M1524001100528
Whether or not the air bags have deployed, check
and service the vehicle after collision as follows:
SRS-ECU MEMORY CHECK
CAUTION
Refer to that the ignition switch is "LOCK" (OFF)
when connecting or disconnecting MUT-II/III.
1. Connect the MUT-II/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
NOTE: If battery power supply has been shut
down by the collision, the MUT-II/III cannot
communicate with the SRS-ECU. Check and,
repair if necessary, the instrument panel wiring
harness before the next job.
3. Use the MUT-II/III to read the data list (how long
trouble(s) have continued and how often memory
have been erased).

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 impact sensors (Refer to
•
Instrument panel (Refer to GROUP 52A
−
Instrument Panel Assembly <LH drive
vehicles>
, <RH drive vehicles >
).
2. Check the following parts and replace if there are
any malfunctions.
•
Clock spring (Refer to
•
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 37A
−
On-Vehicle Service
3. Check the harness for binding, connectors for
damage, poor connections, and 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 seatback assembly (Refer to GROUP 52A
−
).
2. Check the harness for binding, connectors for
damage, poor connections, and terminals for
deformation (Refer to
).
WHEN AIR BAGS DO NOT DEPLOY IN
LOW-SPEED COLLISION.
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 INDIVIDUAL COMPONENT SERVICE,
Front impact sensor
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).

SRS-ECU
1. Check the SRS-ECU case and brackets for dents,
cracks or deformation.
2. Check the connector for damage, and the
terminals for deformation.
3. Check the SRS-ECU and bracket for installation
condition.
Air bag modules
1. Check the pad cover for dents, cracks or
deformation.
2. Check the connector for damage, terminals
deformities, and the harness for binding.
3. Check the air bag inflator case for dents, cracks or
deformities.
4. Check the air bag modules for proper installation.
Front seatback assembly (Side air bag module)
1. Check the side air bag module deployment
section in the seat for dents and deformation.
2. Check the connectors for damage, the terminals
for deformation, and the harness for binds.
Clock spring
1. Check the clock spring connectors and protective
tube for damage, and the terminals for
deformation.
2. Visually check the case for damage.
Side impact sensor
1. Check the centre pillar for deformation or rust.
2. Check the side impact sensors for dents, cracks,
deformation and rust.
3. Check the connector for damage and the
terminals for deformation.
