Inspection Procedure

HINT:

• Perform the simulation method by selecting the "CHECK MODE" (signal check) with the intelligent tester (see DTC CHECK / CLEAR ).
• After selecting the "CHECK MODE" (signal check), perform the simulation method by wiggling each connector of the airbag system or driving the vehicle on a city or rough road (see DTC CHECK / CLEAR ).

1. CHECK CURTAIN SHIELD AIRBAG ASSEMBLY LH (DRIVER SIDE CURTAIN SHIELD SQUIB) 
   1. Turn the ignition switch OFF.
   2. Disconnect the cable from the negative (-) battery terminal, and wait for at least 90 seconds.
   3. Disconnect the connector from the curtain shield airbag LH.
   4. Connect the white wire side of SST (resistance 2.1 Ω) to connector C.
      CAUTION: Never connect a tester to the curtain shield airbag LH (driver side curtain shield squib) for measurement, as this may lead to a serious injury due to airbag deployment.
      NOTE:

      • Do not forcibly insert SST into the terminals of the connector when connecting.
      • Insert SST straight into the terminals of the connector.

      SST 09843-18060 

   5. Connect the cable to the negative (-) battery terminal, and wait for at least 2 seconds.
   6. Turn the ignition switch ON, and wait for at least 60 seconds.
   7. Clear the DTCs (see DTC CHECK / CLEAR ).
   8. Turn the ignition switch OFF.
   9. Turn the ignition switch ON, and wait for at least 60 seconds.
   10. Check the DTCs (see DTC CHECK / CLEAR ).

   OK: DTC B1830, B1831, B1832, B1833 or 57 is not output. 

   HINT:

   DTCs other than DTC B1830, B1831, B1832, B1833 or 57 may be output at this time, but they are not related to this check.

   OK: REPLACE CURTAIN SHIELD AIRBAG ASSEMBLY LH 

   NG: GO to Next Step 

2. CHECK CONNECTOR 
   1. Turn the ignition switch OFF.
   2. Disconnect the cable from the negative (-) battery terminal, and wait for at least 90 seconds.
   3. Disconnect SST from connector C.
   4. Check that the floor wire connector (on the curtain shield LH side) is not damaged.

   OK: Lock button is not disengaged, and claw of lock is not deformed or damaged. 

   NG: REPAIR OR REPLACE FLOOR WIRE 

   OK: GO to Next Step 

3. CHECK FLOOR WIRE (DRIVER SIDE CURTAIN SHIELD SQUIB CIRCUIT) 
   1. Disconnect the connector from the center airbag sensor.
   2. Connect the cable to the negative (-) battery terminal, and wait for at least 2 seconds.
   3. Turn the ignition switch ON.
   4. Measure the voltage of the wire harness side connector.
