Toyota RAV4 (XA40) 2013-2018 Service Manual: Short in driver side curtain shield squib circuit
![Toyota RAV4. Short in driver side curtain shield squib circuit](images/books/256/66/4.htm58.jpg)
Description
The driver side curtain shield squib circuit consists of the center airbag
sensor and the curtain shield
airbag lh.
The circuit instructs the srs to deploy when the deployment conditions are met.
These dtcs are recorded when a malfunction is detected in the driver side
curtain shield squib circuit.

Inspection procedure
Hint:
- Perform the simulation method by selecting the "check mode" (signal
check) with the intelligent
tester (see page rs-49).
- 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 (see page rs-49).
- Check curtain shield airbag assembly lh (driver side curtain shield
squib)
![Toyota RAV4. Check curtain shield airbag assembly lh (driver side curtain shield squib)](images/books/256/66/4.htm61.jpg)
- Turn the ignition switch off.
- Disconnect the cable from the negative (-) battery
terminal, and wait for at least 90 seconds.
- Disconnect the connector from the curtain shield airbag
lh.
- Connect the white wire side of sst (resistance 2.1 Ù) to
connector c.
Caution:
Never connect a tester to the curtain shield airbag
lh (driver side curtain shield squib) for
measurement, as this may lead to a serious injury
due to airbag deployment.
Notice:
- Do not forcibly insert sst into the terminals of the
connector when connecting.
- Insert sst straight into the terminals of the
connector.
Sst 09843-18060
- Connect the cable to the negative (-) battery terminal,
and wait for at least 2 seconds.
- Turn the ignition switch on, and wait for at least 60
seconds.
- Clear the dtcs (see page rs-49).
- Turn the ignition switch off.
- Turn the ignition switch on, and wait for at least 60
seconds.
- Check the dtcs (see page rs-49).
Ok:
dtc b1830, b1831, b1832, b1833 or 57 is not
output.
Hint:
Dtcs other than dtc b1830, b1831, b1832, b1833 or
57 may be output at this time, but they are not related to
this check.
