DTC Detecting Condition

Trouble Area

B1161/84

  • Open circuit in ICR+ wire harness or ICR- wire harness of curtain shield squib RH
  •  Curtain shield squib RH malfunction
  •  Center airbag sensor assembly malfunction
  • Curtain shield airbag assembly RH (Curtain shield squib RH)
  •  Center airbag sensor assembly
  •  Floor wire No. 2

INSPECTION PROCEDURE

HINT:

1 CHECK CURTAIN SHIELD AIRBAG ASSEMBLY RH (CURTAIN SHIELD SQUIB RH)

CHECK CURTAIN SHIELD AIRBAG ASSEMBLY RH (CURTAIN SHIELD SQUIB RH)

  1. Turn the ignition switch to the LOCK position.
  2.  Disconnect the negative (-) terminal cable from the battery, and wait for at least 90 seconds.
  3.  Disconnect the connectors from the curtain shield airbag assembly RH.
  4. Connect the white wire side of SST (resistance 2.1 Ω) to the floor wire No. 2.

CAUTION: Never connect a tester to the curtain shield airbag assembly RH (Curtain shield squib RH) for measurement, as this may lead to a serious injury due to airbag deployment.

NOTICE: Do not forcibly insert the SST into the terminals of the connector when connecting.

Insert the SST straight into the terminals of the connector.

SST 09843-18060

  1. Connect the negative (-) terminal cable to the battery, and wait for at least 2 seconds.
  2.  Turn the ignition switch to the ON position, and wait for at least 60 seconds.
  3.  Clear the DTCs stored in memory (5).
  4.  Turn the ignition switch to the LOCK position.
  5.  Turn the ignition switch to the ON position, and wait for at least 60 seconds.
  6.  Check the DTCs

OK: DTC B1161/84 is not output.

HINT: Codes other than DTC B1161/84 may be output at this time, but they are not related to this check

REPLACE CURTAIN SHIELD AIRBAG ASSEMBLY RH

2 CHECK FLOOR WIRE NO.2 (CURTAIN SHIELD SQUIB RH CIRCUIT)

CHECK FLOOR WIRE NO.2 (CURTAIN SHIELD SQUIB RH CIRCUIT)

  1. Turn the ignition switch to the LOCK position.
  2.  Disconnect the negative (-) terminal cable from the battery, and wait for at least 90 seconds.
  3.  Disconnect the SST (resistance 2.1 Ω) from the floor wire No. 2.
  4.  Disconnect the connector from the center airbag sensor assembly.
  5.  Measure the resistance according to the value(s) in the table below.

Standard resistance

REPAIR OR REPLACE FLOOR WIRE NO.2

3 CHECK CENTER AIRBAG SENSOR ASSEMBLY

CHECK CENTER AIRBAG SENSOR ASSEMBLY

  1. Connect the connectors to the curtain shield airbag assembly RH and the center airbag sensor assembly.
  2.  Connect the negative (-) terminal cable to the battery, and wait for at least 2 seconds.
  3.  Turn the ignition switch to the ON position, and wait for at least 60 seconds.
  4.  Clear the DTCs stored in memory (5).
  5.  Turn the ignition switch to the LOCK position.
  6.  Turn the ignition switch to the ON position, and wait for at least 60 seconds.
  7.  Check the DTCs (5).

OK: DTC B1161/84 is not output. HINT: Codes other than DTC B1161/84 may be output at this time, but they are not related to this check.
