B0118/46

DESCRIPTION

The side squib LH circuit consists of the center airbag sensor assembly and the front seat side airbag assembly LH (side squib LH).
This circuit instructs the SRS to deploy when deployment conditions are met.
DTC B0118/46 is recorded when a short to B+ is detected in the side squib LH circuit.

INSPECTION PROCEDURE

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

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 LH.

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 LH (Side squib LH) 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.

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

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

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

8. Turn the ignition switch to the LOCK position.

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

10. Check the DTCs (Click here).

    OK:

    DTC B0118/46 is not output.
    

    HINT:

    Codes other than DTC B0118/46 may be output at this time, but they are not related to this check.

OK
REPLACE FRONT SEAT SIDE AIRBAG ASSEMBLY LH

2. CHECK CONNECTORS

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. Check that the floor wire No.2 connectors (on the front seat side airbag assembly LH side) are not damaged.

   OK:

   The lock button is not disengaged, and the claw of the lock is not deformed or damaged.
   

NG	REPAIR OR REPLACE FLOOR WIRE NO.2

OK

3. CHECK FLOOR WIRE NO.2 (SIDE SQUIB LH CIRCUIT)

1. Disconnect the connector from 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.

4. Measure the voltage according to the value(s) in the table below.

   Voltage:

   Tester connection	Condition	Specified condition
   S8-1 (SFL+) - Body ground	Ignition switch ON	Below 1 V
   S8-2 (SFL-) - Body ground	Ignition switch ON	Below 1 V

NG	REPAIR OR REPLACE FLOOR WIRE NO.2

OK

4. CHECK CENTER AIRBAG SENSOR ASSEMBLY

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

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

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

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

7. Turn the ignition switch to the LOCK position.

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

9. Check the DTCs (Click here).

   OK:

   DTC B0118/46 is not output.
   

   HINT:

   Codes other than code B0118/46 may be output at this time, but they are not related to this check.

NG	REPLACE CENTER AIRBAG SENSOR ASSEMBLY

OK
