PRECAUTION
CAUTION:
The vehicle is equipped with a Supplemental Restraint System (SRS), which consists of a steering pad, front
passenger airbag, curtain shield airbag, front seat side airbag, seat belt pretensioner, center airbag sensor, front
airbag sensor, side airbag sensor, rear airbag sensor, occupant classification ECU and seat position airbag sensor.
Failure to carry out service procedures in the correct sequence could cause SRS parts to unexpectedly deploy and
possibly lead to serious injuries. Furthermore, if a mistake is made when service SRS parts, they may fail to
operate when required. Before performing servicing (including installation/removal, inspection and replacement of
parts), be sure to read the following precautions.
Before starting work, wait at least 90 seconds after the power switch is turned OFF and after the cable of the
negative (-) battery terminal is disconnected. (SRS parts are equipped with a back-up power source. If work is
started within 90 seconds of turning the power switch OFF and disconnecting the cable from the negative (-)
battery terminal, SRS parts may deploy.)
(The SRS is equipped with a back-up power source, so if work is started within 90 seconds of disconnecting
the negative (-) terminal cable of the battery, the SRS may be deployed).
Do not expose the steering pad, front passenger airbag, center airbag sensor, front airbag sensor, front seat inner
belt, seat position airbag sensor, occupant classification ECU, front seat airbag, side airbag sensor, curtain shield
airbag, rear seat airbag, rear airbag sensor, front seat outer belt or rear seat outer belt directly to hot air or
flames.
NOTICE:
Malfunction symptoms of SRS parts are difficult to confirm. DTCs are the most important source of information
when troubleshooting. During troubleshooting, always confirm DTCs before disconnecting the cable from the
negative (-) battery terminal.
Even in the case of a minor collision when the SRS does not deploy, the steering pad, front passenger airbag,
center airbag sensor, front airbag sensor, front seat inner belt, seat position airbag sensor, occupant classification
ECU, front seat side airbag, side airbag sensor, curtain shield airbag, rear seat airbag, rear airbag sensor, front
seat outer belt or rear seat outer belt should be inspected.
Before repair work, remove airbag sensors as necessary if any kind of impact is likely to occur to an airbag sensor
during the operation.
Never use SRS parts from another vehicle. When replacing SRS parts, replace them with new ones.
Never disassemble or attempt to repair SRS parts.
If an SRS part has been dropped, or if there are any cracks, dents or other defects in the case, bracket or
connector, replace the SRS part with a new one.
Use an ohmmeter/voltmeter with high impedance (10 kƻ/V minimum) for troubleshooting the electrical circuits.
Information labels are attached to the periphery of SRS parts. Follow the cautions and instructions on the labels.
After work on SRS parts is completed, perform the SRS warning light check .
When the cable is disconnected from the negative (-) battery terminal, the memory settings of each system will
be cleared. Because of this, be sure to write down the settings of each system before starting work. When work is
finished, reset the settings of each system as before. Never use a back-up power supply from outside the vehicle
to avoid erasing the memory in a system.
If the vehicle is equipped with a mobile communication system, refer to the precaution in the INTRODUCTION
section .
When disconnecting the cable from the negative (-) battery terminal, initialize the following system(s) after the
cable is reconnected.

1. HANDLING PRECAUTIONS FOR AIRBAG SENSORS
(a) Before starting the following operations, wait for at least 90 seconds after disconnecting the negative (-) terminal
cable from the battery:
(1) Replacement of the airbag sensors.
(2) Adjustment of the front/rear doors of the vehicle equipped with the side airbag and curtain shield airbag
(fitting adjustment).
(b) When connecting or disconnecting the airbag sensor connectors, ensure that each sensor is installed in the
vehicle.
(c) Do not use the airbag sensors which has been dropped during the operation or transportation.
(d) Do not disassemble the airbag sensors.
2. INSPECTION PROCEDURE FOR VEHICLE INVOLVED IN ACCIDENT
(a) When the airbag has not deployed, confirm the DTCs by checking the SRS warning light. If there is any
malfunction in the SRS airbag system, perform troubleshooting.
(b) When any of the airbags have deployed, replace the airbag sensors and check the installation condition.
3. SRS CONNECTORS
(a) SRS connectors are located as shown in the following illustration.

NO. ITEM APPLICATION
(1) Terminal Twin-Lock Mechanism Connectors 5, 6, 7, 9, 10, 15, 19, 20, 23, 27, 28
(2) Activation Prevention Mechanism Connectors 2, 4, 10, 12, 20, 22, 26, 28, 30
(3) Half Connection Prevention Mechanism Connectors 6, 7, 9, 15, 19, 23, 27
(4) Connector Lock Mechanism (1) Connectors 11, 21, 25, 29
(5) Connector Lock Mechanism (2) Connectors 2, 4
(6) Improper Connection Prevention Lock Mechanism Connectors 1, 3
(b) All connectors in the SRS, except the seat position airbag sensor connector, are colored yellow to distinguish them
from other connectors. These connectors have special functions, and are specially designed for the SRS. All SRS
connectors use durable gold-plated terminals, and are placed in the locations shown above to ensure high
reliability.
(1) Terminal twin-lock mechanism:
All connectors with a terminal twin-lock mechanism have a two-piece component consisting of a housing and a
spacer. This design enables the terminal to be locked securely by two locking devices (the retainer and the
lance) to prevent terminals from coming out.
(2) Activation prevention mechanism:
All connectors with an activation prevention mechanism contain a short spring plate. When these connectors
are disconnected, the short spring plate creates a short circuit by automatically connecting the positive (+)
and negative (-) terminals of the squib.
SUPPLEMENTAL RESTRAINT SYSTEM: AIRBAG SYSTEM: PRECAUTION (2009 Prius)
2004-2009 Toyota Prius Service Manual

(3) Half connection prevention mechanism:
If the connector is not completely connected, the connector is disconnected due to the spring operation so that
no continuity exists.
(4) Connector position assurance mechanism:
Only when the housing lock (white part) is completely engaged, the CPA (yellow part) slides, which completes
the connector engagement.
(5) Connector lock mechanism (1):
Locking the connector lock button connects the connector securely.
(6) Connector lock mechanism (2):
Both the primary lock with holder lances and the secondary lock with retainer prevent the connectors from
being disconnected.
