Toyota Sienna Service Manual: USE SIMULATION METHOD TO CHECK
DTC B0113/42 Short to B+ 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.
This circuit instructs the SRS to deploy when deployment conditions are met.
DTC B0113/42 is recorded when a short to B+ is detected in the side squib RH
circuit.
WIRING DIAGRAM
INSPECTION PROCEDURE
HINT:
- Perform the simulation method by selecting the "check mode"
(signal check) with the intelligent tester.
- 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
1 CHECK FRONT SEAT SIDE AIRBAG ASSEMBLY RH (SIDE SQUIB RH)
- Turn the ignition switch to the LOCK position.
- Disconnect the negative (-) terminal cable from the
battery, and wait for at least 90 seconds.
- Disconnect the connectors from the front seat side
airbag assembly RH.
- 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
- Connect the negative (-) terminal cable to the battery,
and wait for at least 2 seconds.
- Turn the ignition switch to the ON position, and wait for at
least 60 seconds.
- Clear the DTCs stored in memory.
- Turn the ignition switch to the LOCK position.
- Turn the ignition switch to the ON position, and wait for at
least 60 seconds.
- Check the DTCs
OK:
DTC B0113/42 is not output.
HINT:
Codes other than DTC B0113/42 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)
- Turn the ignition switch to the LOCK position.
- Disconnect the negative (-) terminal cable from the
battery, and wait for at least 90 seconds.
- Disconnect the SST (resistance 2.1 Ω) from the floor
wire No. 2.
- Disconnect the connector from the center airbag sensor
assembly.
- Connect the negative (-) terminal cable to the battery,
and wait for at least 2 seconds.
- Turn the ignition switch to the ON position.
- Measure the voltage according to the value(s) in the
table below.
Standard voltage
3 CHECK CENTER AIRBAG SENSOR ASSEMBLY
- Turn the ignition switch to the LOCK position.
- Disconnect the negative (-) terminal cable from the
battery, and wait for at least 90 seconds.
- Connect the connectors to the front seat side airbag
assembly RH and the center airbag sensor assembly.
- Connect the negative (-) terminal cable to the battery,
and wait for at least 2 seconds.
- Turn the ignition switch to the ON position, and wait for at
least 60 seconds.
- Clear the DTCs stored in memory.
- Turn the ignition switch to the LOCK position.
- Turn the ignition switch to the ON position, and wait for at
least 60 seconds.
- Check the DTCs.
OK:
DTC B0113/42 is not output.
HINT:
Codes other than code B0113/42 may be output at this
time, but they are not related to this check.
