Toyota RAV4. Front passenger side - side airbag sensor circuit malfunction


Description

The side airbag sensor rh consists of parts including the diagnostic circuit and the lateral deceleration sensor.

When the center airbag sensor receives signals from the lateral deceleration sensor, it determines whether or not the srs should be activated.

Dtc b1625/22 is set when a malfunction is detected in the side airbag sensor rh circuit.

Inspection procedure

  1. Check side airbag sensor rh

Toyota RAV4. Check side airbag sensor rh


  1. Turn the ignition switch off.
  2. Disconnect the cable from the negative (-) battery terminal, and wait for at least 90 seconds.
  3. Interchange the side airbag sensor rh and the side airbag sensor lh, and connect the connectors to them.
  4. Connect the cable to the negative (-) battery terminal, and wait for at least 2 seconds.
  5. Turn the ignition switch on, and wait for at least 60 seconds.
  6. Clear the dtcs (see page rs-49).
  7. Turn the ignition switch off.
  8. Turn the ignition switch on, and wait for at least 60 seconds.
  9. Check the dtcs (see page rs-49).

Result


Dtcs other than dtc b1620/21 and b1625/22 may be output at this time, but they are not related to this check.

Symptom confirmation and diagnostic trouble code
Hint: The diagnostic system in the rav4 has various functions. The first function is the diagnostic trouble code (dtc) check. A dtc is a code stored in the ecu memory whenever a malfunction in the signal circuits to the ecu occurs. In a dtc check, a previous malfunction's dtc can be ch ...
