SRS - SRS Maintenance52B-42
SRS MAINTENANCE
The SRS must be inspected by an authorized dealer 10 years
after the date of vehicle registration.
SRS WARNING LAMP CHECK
Turn the ignition switch to the ON position. Does the SRS
warning lamp illuminate for about 7 seconds, and then go
out? If yes, SRS system is functioning properly. If no, refer
to page 52B-6.
SRS COMPONENT VISUAL CHECK
Turn the ignition key to LOCK (OFF) position, disconnect
the negative ( - ) battery cable and tape the terminal.
Caution
Wait at least 60 seconds after disconnecting the battery
cable before doing any further work. (Refer to P.52B-3.)
SRS CONTROL UNIT (SRS-ECU)
1. Check SRS-ECU case and brackets for dents, cracks,
deformation or rust.
Caution
The SRS may not activate if the SRS-ECU is not
installed properly, which could result in serious injury
or death to the vehicle’s driver or front passenger.
2. Check connector for damage, and terminals for
deformation or rust.
Replace SRS-ECU if it fails visual check.

Caution
1. Disconnect the negative ( - ) battery terminal
and wait for 60 seconds or more before
starting work. Also, the disconnected
battery terminal should be insulated with
tape. (Refer to P.52B-3.)
2. Never attempt to disassemble or repair the
SRS-ECU. If faulty, just replace with a new
one.3. Do not drop or subject the SRS-ECU to
impact or vibration.
If denting, cracking, deformation, or rust are
found in the SRS-ECU, replace it with a new
one. Discard the old one.
4. After deployment of the air bags, replace
the SRS-ECU with a new one.
5. Never use an ohmmeter on or near the
SRS-ECU, and use only the special test
equipment described on P.52B-6.

SRS -Seat Belt with Pre-tensioner52B-61
SEAT BELT WITH PRE-TENSIONER
Caution:
1. Wait for at least 60 seconds after
disconnecting the negative ( - ) terminal of
the battery before starting any operation.The
removed negative ( - ) terminal must be
protected by wrapping the tape. (Refer to
P.52B-3.)
2. Never disassemble or repair the seat belt
with pre-tensioner. Replace the part with a
new one when it malfunctions.
3. Take an extra care to deal with the seat belt
with pre-tensioner by avoiding dropping or
wetting it with water or oil. If any dent, crack,
or deformation is found, be sure to replace
the seat belt with pre-tensioner with a new
part.4. Do not place a heavy object on top of the
seat belt pre-tensioner.
5. Never keep the seat belt with pre-tensioner
in a place where the temperature can exceed
over 90_C.
6. Replace the seat belt with pre-tensioner with
a new one after operating the seat belt
pre-tensioner.
7. Wear gloves or protective glasses when
handling the seat belt with pre-tensioner
after operation.
8. If the seat belt with pre-tensioner before
operation needs to be discarded, be sure
to do so after operating the seat belt
pre-tensioner. (Refer to P.52B-64.)

"AAPRE-INSTALLATION INSPECTION
1. Pre-installation inspection must be carried out even when
installing a new seat belt with pre-tensioner. (Refer to
Inspections.)
Caution
If the seat belt with pre-tensioner is discarded, discard
it after operating the seat belt pre-tensioner according
to the specified procedure. (Refer to P.52B-64.)
2. Connect the negative ( - ) terminal of the battery.
3. Connect the MUT-II to the diagnosis connector (16 pin).
Caution
Connection and disconnection of the MUT-II must be
carried out after turning the ignition switch to the
LOCK (OFF) position.
4. Turn the ignition switch to ON position.
5. Check that there is no abnormality except for open circuit
in the seat belt pre-tensioner after reading diagnostic
codes.
6. Turn the ignition key to LOCK (OFF) position.
7. Release the negative ( - ) terminal cable of the battery
and wrap a tape around it for insulation.
Caution
Wait for at least 60 seconds after disconnecting the
negative ( - ) battery cable before starting any
operation. (Refer to P.52B-3.)
"BAPOST-INSTALLATION INSPECTION
1. Turn the ignition switch to the ON position.
