Toyota RAV4 (XA40) 2013-2018 Service Manual: Short in front passenger side curtain shield squib circuit

Description
The front passenger side curtain shield squib circuit consists of the center
airbag sensor and the curtain
shield 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 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-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 curtain shield airbag assembly rh (front passenger side curtain
shield squib)

- Turn the ignition switch off.
- Disconnect the cable from the negative (-) battery
terminal, and wait for at least 90 seconds.
- Disconnect the connectors from the curtain shield airbag
rh.
- Connect the white wire side of sst to connector c.
Caution:
Never connect a tester to the curtain shield airbag
rh (front passenger 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 b1835, b1836, b1837, b1838 or 58 is not
output.
Hint:
Dtcs other than dtc b1835, b1836, b1837, b1838 or
58 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 c.
- Check that the floor wire connector (on the curtain shield
airbag rh side) is not damaged.
Ok:
lock button is not disengaged, and claw of lock is
not deformed or damaged.

- Check floor wire no.2 (Front passenger side curtain shield squib
circuit)

- Disconnect the connectors 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:
W/ sliding roof
W/o sliding roof
- 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:
W/ sliding roof 
W/o sliding roof 
- Release the activation prevention mechanism built into
connector b (see page rs-37).
- Measure the resistance of the wire harness side
connector.
Standard resistance:
W/ sliding roof 
W/o sliding roof

Intake air temperature circuit malfunction
Description
The intake air temperature (iat) sensor, mounted on the mass air flow (maf)
meter, monitors the iat.
The iat sensor has a built-in thermistor with a resistance that varies according
to the temperature of the
intake air. When the iat is low, the resistance of the thermist ...
