DTC Detecting Condition

Trouble Area

B0112/41

  • Short circuit in side squib RH wire harness (to ground)
  •  Side squib RH malfunction
  •  Center airbag sensor assembly malfunction
  • Front seat side airbag assembly RH (Side squib RH)
  •  Center airbag sensor assembly
  •  Floor wire No. 2

INSPECTION PROCEDURE

HINT:

1 CHECK FRONT SEAT SIDE AIRBAG ASSEMBLY RH (SIDE SQUIB RH)

CHECK FRONT SEAT SIDE AIRBAG ASSEMBLY RH (SIDE 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 front seat side airbag assembly RH.
  4.  Connect the black wire side of SST (resistance 2.1 Ω) to the floor wire No. 2.

CAUTION: Never connect a tester to the front seat side airbag assembly RH (side 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 B0112/41 is not output.

HINT: Codes other than DTC B0112/41 may be output at this time, but they are not related to this check.

REPLACE FRONT SEAT ASSEMBLY RH

2 CHECK FLOOR WIRE NO.2 (SIDE SQUIB RH CIRCUIT)

CHECK FLOOR WIRE NO.2 (SIDE 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 front seat side 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 B0112/41 is not output. HINT: Codes other than code B0112/41 may be output at this time, but they are not related to this check.
