Airbag System

SUPPLEMENTAL RESTRAINT SYSTEM: AIRBAG SYSTEM: B0110/43: Short in Side Squib RH Circuit

DTC B0110/43 - Short in Side Squib RH Circuit

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 B0110/43 is recorded when a short circuit is detected in the side squib RH circuit.

INSPECTION PROCEDURE
HINT:
- Perform the simulation method by selecting the "check mode" (signal check) with the Techstream Check Mode Procedure.
- 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 Check Mode Procedure.

PROCEDURE

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





(a) Turn the ignition switch to the LOCK position.
(b) Disconnect the negative (-) terminal cable from the battery, and wait for at least 90 seconds.
(c) Disconnect the connectors from the front seat side airbag assembly RH.
(d) Connect the black wire side of SST (resistance 2.1 Ohms) 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.
NOTE: 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
(e) Connect the negative (-) terminal cable to the battery, and wait for at least 2 seconds.
(f) Turn the ignition switch to the ON position, and wait for at least 60 seconds.
(g) Clear the DTCs stored in memory DTC Check / Clear.
(h) Turn the ignition switch to the LOCK position.
(i) Turn the ignition switch to the ON position, and wait for at least 60 seconds.
(j) Check the DTCs DTC Check / Clear.
OK:
DTC B0110/43 is not output.
HINT: Codes other than DTC B0110/43 may be output at this time, but they are not related to this check.

NG -- CHECK FLOOR WIRE (SIDE SQUIB RH CIRCUIT)
OK -- REPLACE FRONT SEAT ASSEMBLY RH
2. CHECK FLOOR WIRE (SIDE SQUIB RH CIRCUIT)





(a) Turn the ignition switch to the LOCK position.
(b) Disconnect the negative(-) terminal cable from the battery, and wait for at least 90 seconds.
(c) Disconnect the SST (resistance 2.1 Ohms) from the floor wire.
(d) Disconnect the connector from the center airbag sensor assembly.
(e) Release the activation prevention mechanism built into connector "B" Diagnosis System.
(f) Measure the resistance according to the value(s) in the table below.
Standard resistance:






NG -- REPAIR OR REPLACE FLOOR WIRE
OK -- Continue to next step.
3. CHECK CENTER AIRBAG SENSOR ASSEMBLY





(a) Connect the connectors to the front seat side airbag assembly RH and the center airbag sensor assembly.
(b) Connect the negative (-) terminal cable to the battery, and wait for at least 2 seconds.
(c) Turn the ignition switch to the ON position, and wait for at least 60 seconds.
(d) Clear the DTCs stored in memory DTC Check / Clear.
(e) Turn the ignition switch to the LOCK position.
(f) Turn the ignition switch to the ON position, and wait for at least 60 seconds.
(g) Check the DTCs DTC Check / Clear.
OK:
DTC B0110/43 is not output.
HINT: Codes other than code B0110/43 may be output at this time, but they are not related to this check.

NG -- REPLACE CENTER AIRBAG SENSOR ASSEMBLY
OK -- USE SIMULATION METHOD TO CHECK
