Toyota RAV4 Service Manual: Precaution

Caution:

Notice:

Hint:

In the airbag system, the center airbag sensor, front airbag sensor lh and rh, side airbag sensor lh and rh, and rear airbag sensor lh and rh are collectively referred to as the airbag sensors.

  1. Handling precautions for airbag sensors

  1. 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 airbags and curtain shield airbags (fitting adjustment)
  1. When connecting or disconnecting the airbag sensor connectors, ensure that each sensor is installed in the vehicle.
  2. Do not use airbag sensors which have been dropped during the operation or transportation.
  3. Do not disassemble the airbag sensors.
  1. Inspection procedure for vehicle involved in accident

  1. 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.
  2. When any of the airbags have deployed, replace the airbag sensors and check the installation condition.
  1. Srs connector

  1. Srs connectors are located as shown in the following illustration.

  1. All connectors in the srs except the seat position sensor connector and the occupant classification ecu connector are colored yellow to distinguish them from other connectors. Some connectors have special functions, and are specially designed for the srs. These connectors use durable gold-plated terminals, and are placed in the locations shown above to ensure high reliability.
  1. Terminal twin-lock mechanism: each connector is 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 the terminals from becoming disconnected.
  2. Activation prevention mechanism: each connector contains a short spring plate.

    When the connector is disconnected, the short spring plate creates a short circuit by automatically connecting the positive (+) and negative (-) terminals of the squib.

  1. Half connection prevention mechanism: if the connector is not completely connected, the connector is disconnected by the spring operation so that no continuity exists.

  1. Connector position assurance mechanism: the cpa (yellow part) slides, which completes the connector engagement, only when the housing lock (white part) is completely engaged.
