Toyota Sienna Service Manual: Short in Front Pretensioner Squib RH Circuit
DTC B0130/63 Short in Front Pretensioner Squib RH Circuit
DESCRIPTION
The front pretensioner squib RH circuit consists of the center airbag sensor
assembly and the front seat
outer belt assembly RH.
This circuit instructs the SRS to deploy when deployment conditions are met.
DTC B0130/63 is recorded when a short circuit is detected in the front
pretensioner squib RH circuit.

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 OUTER BELT ASSEMBLY RH (FRONT PRETENSIONER 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 outer belt
assembly RH.
- Connect the white wire side of SST (resistance 2.1 Ω) to
the floor wire No. 2.
CAUTION:
Never connect a tester to the front seat outer belt
assembly RH (front pretensioner 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 B0130/63 is not output.
HINT:
Codes other than DTC B0130/63 may be output at this
time, but they are not related to this check.
REPLACE FRONT SEAT OUTER BELT ASSEMBLY RH
2 CHECK CONNECTORS
- 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.
- Check that the floor wire No. 2 connectors (on the front
seat outer belt assembly RH side) are not damaged.
OK:
The lock button is not disengaged, and the claw of
the lock is not deformed or damaged.
3 CHECK FLOOR WIRE NO.2 (FRONT PRETENSIONER SQUIB RH CIRCUIT)
- Disconnect the connector from the center airbag sensor
assembly.
- Release the activation prevention mechanism built into
connector "B".
- Measure the resistance according to the value(s) in the
table below.
Standard resistance
4 CHECK CENTER AIRBAG SENSOR ASSEMBLY
- Connect the connectors to the front seat outer belt
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 B0130/63 is not output.
HINT:
Codes other than code B0130/63 may be output at this
time, but they are not related to this check.
