SRS Precautions and Procedures

SRS Precautions and Procedures

General Precautions


Please read the following precautions carefully before performing the airbag system service. Observe the instructions described in this manual, or the airbags could accidentally deploy and cause damage or injuries.

 

Steering-related Precautions


Cable Reel Alignment



Airbag Handling and Storage


Do not disassemble an airbag. It has no serviceable parts. Once an airbag has been deployed, it cannot be repaired or reused.

For temporary storage of the airbag during service, please observe the following precautions.

 

 

 

 

 

SRS Unit, Front Impact Sensors, and Side Impact Sensors


 

 

Wiring Precautions


Some of the SRS wiring can be identified by special yellow outer covering, and the SRS connectors can be identified by their yellow color.
Observe the instructions.

 

 

Precautions for Electrical Inspections


 

 

Spring-loaded Lock Connector


Some SRS system connectors have a spring-loaded lock.

Front Airbag Connectors


Disconnecting

To release the lock, pull the spring-loaded sleeve (A) toward the stop (B) while holding the opposite half of the connector. Then pull the connector halves apart. Be sure to pull on the sleeve and not on the connector.

 

Connecting

To reconnect, hold the pawl-side connector, and press on the back of the sleeve-side connector in the direction shown. As the two connector halves are pressed together, the sleeve (A) is pushed back by the pawl (C). Do not touch the sleeve.

 

Side Airbag Connector


Disconnecting

To release the lock, pull the spring-loaded sleeve (A) toward the stop (B) while holding the opposite half of the connector. Then pull the connector halves apart. Be sure to pull on the sleeve and not on the connector half.

 

Connecting

Hold both connector halves, and press them firmly together until the projection (C) of the sleeve-side connector clicks.

 

Opening the SRS Unit Shorting Connectors for Diagnosis


NOTE:


When the SRS unit connector is disconnected, a short circuit is created in the connector to prevent an airbag deployment. The circuit needs to be open sometimes when diagnosis is performed on the system. Insert the short canceller (No. 070AZ-SAA0100) in the specified cavities when it is necessary to keep the circuit open for diagnosis.

 

 

 

Seats with Side Airbags


Seats with side airbags have a ‘‘SIDE AIRBAG'' label on the seat-back. Because the component parts (seat-back cover, cushion, etc.) of seats with and without airbags are different, make sure you install only the correct replacement parts.

 

Disconnecting System Connectors


Turn the ignition switch OFF and disconnect the negative cable from the battery, and wait at least 3 minutes before beginning the following procedures.

 

1.Disconnect the negative cable from the battery, and wait at least 3 minutes.

3.Remove the grove box, then disconnect the front passenger's airbag 4P connector (A) from the dashboard wire harness.

 

Side Airbag


4.Disconnect the side airbag 2P connector (A) from the floor harness.

 


Side Curtain Airbag


5.Disconnect the both floor wire harness 2P connector (A) from the side curtain airbag.

 

Seat Belt Tensioner


6.Disconnect the floor wire harness 4P connector (A) from the seat belt tensioners.

 


Seat Belt Outer Lap Tensioner
