SRS Precautions and Procedures

General Precautions


Please read the following precautions carefully before performing 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 airbag during service, observe the following precautions.

 

 

 


 

SRS Unit, Front 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 described in this section.

 


 

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

1.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.

 

2.When the connector halves are completely connected, the pawl is released, and the spring-loaded sleeve locks the connector.

 

Side Airbag Connector:


Disconnecting

To release the lock, pull the spring-loaded sleeve (A) and the slider (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.

 

Backprobing Spring-loaded Lock Connectors


When checking voltage or resistance on this type of connector the first time, you must remove the retainer to insert the tester probe from the wire side.

NOTE: It is not necessary to reinstall the removed retainer; the terminals will stay locked in the connector housing.

 

To remove the retainer (A), insert a flat-tip screwdriver (B) between the connector body and the retainer, then carefully pry out the retainer. Take care not to break the connector.

 

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 the Airbag Connectors, Side Airbag Connectors, Seat Belt Buckle Tensioner Connectors and Seat Belt Tensioner Connectors


Before removing a front airbag, side airbag or other SRS related devices (the SRS unit, the cable reel, the side impact sensors, the seat belt buckle tensioners and the seat belt tensioner connector), disconnecting connectors from related devices, or removing the dashboard or the steering column, disconnect the airbag connectors or the side airbag connectors to prevent accidental deployment.
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 battery cable, and wait at least 3 minutes.

Driver's Airbag


2.Remove the access panel (A) from the steering wheel, then disconnect the driver's airbag 2P connector (1) from the cable reel 2P connector (2).

 

Front Passenger's Airbag


3.Remove the access panel (A), then disconnect the front passenger's airbag 2P connector (1) from the dashboard wire harness B 2P connector (2).

 

Side Airbag


4.Disconnect both side airbag 2P connectors (1) from the floor wire harness 2P connectors (2).

 

Seat Belt Tensioner


5.Disconnect both seat belt tensioner 2P connectors (1) from the floor wire harness 2P connector (2).

 

Seat Belt Buckle Tensioner


6.Disconnect both seat belt buckle tensioner 4P connectors (1).
