Toyota RAV4 Service Manual: Short in front passenger side - side squib circuit

Description
The front passenger side - side squib circuit consists of the center airbag
sensor and the front seat side
airbag rh.
The circuit instructs the srs to deploy when the deployment conditions are met.
These dtcs are recorded when a malfunction is detected in the front passenger
side - side squib circuit.

Inspection procedure
Hint:
- Perform the simulation method by selecting the "check mode" (signal
check) with the intelligent
tester (see page rs-52).
- 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-52).
- Check front seat side airbag assembly rh (front passenger side - side
squib)

- 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 front seat side airbag
rh.
- Connect the black wire side of sst to connector c.
Caution:
Never connect a tester to the front seat side airbag
rh (front passenger side - side 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 b1825, b1826, b1827, b1828 or 56 is not
output.
Hint:
Dtcs other than dtc b1825, b1826, b1827, b1828 or
56 may be output at this time, but they are not related to
this check.

- Check connector
- Turn the ignition switch off.
- Disconnect the cable from the negative (-) battery
terminal, and wait for at least 90 seconds.
- Disconnect sst from connector e.
- Check that the no. 2 Seat airbag wire connectors (on the
front passenger side - side squib) are not damaged.
Ok:
lock button is not disengaged, and claw of lock is
not deformed or damaged.

- Check no. 2 Floor wire (front passenger side - side squib circuit)

- Disconnect the connector from the center airbag sensor.
- Connect the cable to the negative (-) battery terminal,
and wait for at least 2 seconds.
- Turn the ignition switch on.
- Measure the voltage of the wire harness side connector.
Standard voltage 
- Turn the ignition switch off
- Disconnect the cable from the negative (-) battery
terminal, and wait for at least 90 seconds.
- Measure the resistance of the wire harness side
connector.
Standard resistance 
- Release the activation prevention mechanism built into
connector b (see page rs-37).
- Measure the resistance of the wire harness side
connector.
Standard resistance 

- Check no. 2 Seat airbag wire

- Disconnect the no. 2 Seat airbag wire from the no. 2
Floor wire.
- Connect the cable to the negative (-) battery terminal,
and wait for at least 2 seconds.
- Turn the ignition switch off.
- Measure the voltage of the wire harness side connector.
Standard voltage 
- Turn the ignition switch off.
- Disconnect the cable from the negative (-) battery
terminal, and wait for at least 90 seconds
- Measure the resistance of the wire harness side
connector.
