for Preparation Click here


DESCRIPTION

The side squib RH circuit consists of the center airbag sensor assembly and the front seat side airbag assembly RH (side squib RH).
The circuit instructs the SRS to deploy when deployment conditions are met.
DTC B0112/41 is recorded when a short to ground is detected in the side squib RH circuit.

DTC No.

INSPECTION PROCEDURE

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


    C110410E01

  1. Turn the ignition switch to the LOCK position.

  1. Disconnect the negative (-) terminal cable from the battery, and wait for at least 90 seconds.

  1. Disconnect the connectors from the front seat side airbag assembly RH.

  1. Connect the black wire side of SST (resistance 2.1 Ω) to the floor wire.

    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.

OK


3.CHECK FLOOR WIRE (SIDE SQUIB RH CIRCUIT)


    C110406E01

  1. Disconnect the connector from the center airbag sensor assembly.

  1. Measure the resistance according to the value(s) in the table below.

    Resistance:
    Tester connection
    		Condition
    		Specified condition
    S9-1 (SFR+) -
    Body ground
    		Always
    		1 MΩ or higher
    S9-2 (SFR-) -
    Body ground
    		Always
    		1 MΩ or higher



NG
REPAIR OR REPLACE FLOOR WIRE
OK


4.CHECK CENTER AIRBAG SENSOR ASSEMBLY


    C110411E01

  1. Connect the connectors to the front seat side airbag assembly RH and the center airbag sensor assembly.

  1. Connect the negative (-) terminal cable to the battery, and wait for at least 2 seconds.

  1. Turn the ignition switch to the ON position, and wait for at least 60 seconds.

  1. Clear the DTCs stored in memory (Click here).

  1. Turn the ignition switch to the LOCK position.
