FRONT AIRBAG SENSOR INSTALLATION

CAUTION / NOTICE / HINT

PROCEDURE

1. INSTALL FRONT AIRBAG SENSOR LH

   
   

   1. Check that the engine switch is off.

   2. Check that the cable is disconnected from the negative (-) battery terminal.

      CAUTION:

      
      

      • 

        Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to disable the SRS system.

      • 

        If this procedure is performed without disconnecting the negative (-) terminal of the battery, the airbag may deploy even if an impact is applied only to the front airbag sensor LH. Therefore, make sure that the negative (-) terminal of the battery is disconnected before performing this procedure.

   3. Attach the guide and hold the front airbag sensor LH in place.

   4. Install the bolt.

      Torque:

      9.0 N*m  { 92 kgf*cm, 80 in.*lbf }

      Note

      
      

      • If the front airbag sensor LH has been dropped, replace it with a new one.

      • When installing the front airbag sensor LH, be careful that the SRS wiring does not interfere with or is not pinched between other parts.

      • Tighten the bolt while holding the front airbag sensor LH because the front airbag sensor LH guide is easily damaged.

   5. Connect the airbag connector.

      Note

      When connecting any airbag connector, take care not to damage the airbag wire harness.

      
      

      1. Before connecting the connector, check that the position of the housing lock is correct as shown in the illustration.

         

         *a

         Incorrect

         *b

         Correct

      2. While holding the CPA be sure to engage the connectors until they are locked and check that the CPA is in its original position (when locking, make sure that a click sound can be heard).

         Tech Tips

         When engaged, the white housing lock will slide. Be sure not to hold the white housing lock and upper part of the CPA, as it may result in an insecure fit.
