Front Airbag Sensor: Installation: Installation

HINT: 

• Use the same procedure for the RH side and LH side.
• The procedure listed below is for the LH side.

1. INSTALL FRONT AIRBAG SENSOR 
   1. Check that the power switch is off.
   2. Check that the cable is disconnected from the negative (-) auxiliary battery terminal.
      WARNING:

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

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

      *a	Fulcrum Length

      without SST 

      Torque: 9.0 N*m (92 kgf*cm, 80 in.*lbf) 

      with SST 

      Torque: 5.6 N*m (57 kgf*cm, 50 in.*lbf) 

      NOTE:

      • Use a torque wrench with a fulcrum length of 250 mm (9.84 in.).
      • This torque value is effective when SST is parallel to the torque wrench.
      • If the front airbag sensor has been dropped, or there are any cracks, dents or other defects in the case or connector, replace it with a new one.
      • When installing the front airbag sensor, be careful that the SRS wiring does not interfere with or is not pinched between other parts.
      • Make sure that the pin (stopper) is securely inserted into the body hole.
      • Tighten the bolt while holding the front airbag sensor because the front airbag sensor pin (stopper) is easily damaged.
   6. Connect the connector to the front airbag sensor.
      NOTE:

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

      1. Be sure to engage the connectors until they are locked (when locking, make sure that a click sound can be heard).

         HINT: 

         When engaged, the white housing lock will slide. Be sure not to hold the white housing lock or part (A), as it may result in an insecure fit.

   7. Check that there is no looseness in the installation parts of the front airbag sensor.
2. CONNECT CABLE TO NEGATIVE AUXILIARY BATTERY TERMINAL 
   NOTE:

   When disconnecting the cable, some systems need to be initialized after the cable is reconnected. Refer to INITIALIZATION .

3. INSTALL FRONT BUMPER ASSEMBLY 

   Refer to INSTALLATION

4. INSTALL REAR NO. 3 FLOOR BOARD UPPER PLATE  . Refer to INSTALLATION - Step 3
5. INSTALL DECK FLOOR BOX RH  . Refer to INSTALLATION - Step 4
6. INSTALL REAR NO. 3 FLOOR BOARD  . Refer to INSTALLATION - Step 55
7. PERFORM DIAGNOSTIC SYSTEM CHECK 

   Refer to DTC CHECK / CLEAR

8. INSPECT SRS WARNING LIGHT 

   Refer to DIAGNOSIS SYSTEM
