Toyota RAV4 (XA40) 2013-2018 Service Manual: Front airbag sensor lh circuit malfunction
Description
The front airbag sensor lh consists of the diagnostic circuit, the frontal deceleration sensor, etc.
If the center airbag sensor receives signals from the frontal deceleration sensor, it determines whether or not the srs should be activated.
Dtc b1615/14 is recorded when a malfunction is detected in the front airbag sensor lh circuit.
Wiring diagram
Inspection procedure
- Check front airbag sensor lh
- Turn the ignition switch off.
- Disconnect the cable from the negative (-) battery terminal, and wait for at least 90 seconds.
- Interchange the front airbag sensor rh and lh, and connect the connectors to them.
- 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).
