SRS ± SRS Service Precautions
52B-4
SRS SERVICE PRECAUTIONS
1. In order to avoid injury to yourself or others
from accidental deployment of the air bag during
servicing, read and carefully follow all the
precautions and procedures described in this
manual.
2. Do not use any electrical test equipment on
or near SRS components, except those
specified on P.52B-7.
3. Never Attempt to Repair the Following
Components:
D SRS air bag control unit (SRS-ECU)
D Front impact sensor
D Clock spring
D Driver's and front passenger's air bag
modules
D Side air bag module
D Side impact sensor
D Seat belt with pre-tensioner
NOTE
If any of these components are diagnosed as
faulty, they should only be replaced, in
accordance with the INDIVIDUAL COM-
PONENTS SERVICE procedures in this
manual. (Refer to P.52B-30.)
4. After disconnecting the negative (±) battery cable, wait
60 seconds at least before any service and insulate
the disconnected cable with tape. The SRS retain
enough voltage to deploy the air bag for a short time
even after disconnection of the battery. So, serious
injury may result by accidental air bag deployment
if a work is done on the SRS just after the disconnection
of the battery.
5. Do not attempt to repair the wiring harness connectors
of the SRS. If the connector(s) are diagnosed as defective,
replace the wiring harness(es). If the harness(es) are
diagnosed as faulty, replace or repair the wiring
harness(es) according to the following table.
