Toyota RAV4 Service Manual: Short in driver side squib circuit

Toyota RAV4. Short in driver side squib circuit


Description

The driver side squib circuit consists of the center airbag sensor, the spiral cable and the steering pad.

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 squib circuit.

Inspection procedure

Hint:

  1. Check steering pad (driver side squib)

 

  1. Turn the ignition switch off.
  2. Disconnect the cable from the negative (-) battery terminal, and wait for at least 90 seconds.
  3. Disconnect the connectors from the steering pad.
  4. Connect the white wire side of sst (resistance 2.1 Ù) to connector e.

Caution:

Never connect a tester to the steering pad (driver side squib) for measurement, as this may lead to a serious injury due to airbag deployment.

Notice:

Sst 09843-18060

  1. Connect the cable to the negative (-) battery terminal, and wait for at least 2 seconds.
  2. Turn the ignition switch on (ig), and wait for at least 60 seconds.
  3. Clear the dtcs (see page rs-49).
  4. Turn the ignition switch off.
  5. Turn the ignition switch on, and wait for at least 60 seconds.
  6. Check the dtcs (see page rs-49).

Ok: dtc b1800, b1801, b1802, b1803 or 51 is not output.

Hint:

Dtcs other than dtc b1800, b1801, b1802, b1803 or 51 may be output at this time, but they are not related to this check.


  1. Check connector

  1. Turn the ignition switch off.
  2. Disconnect the cable from the negative (-) battery terminal, and wait for at least 90 seconds.
  3. Disconnect sst from the spiral cable.
  4. Check that the spiral cable connectors (on the steering pad side) are not damaged.

Ok: lock button is not disengaged, and claw of lock is not deformed or damaged.

  1. Disconnect the connectors from the center airbag sensor.
  2. Connect the cable to the negative (-) battery terminal, and wait for at least 2 seconds.
  3. Turn the ignition switch on.
  4. Measure the voltage of the wire harness side connector

Standard voltage


  1. Turn the ignition switch off.
  2. Disconnect the cable from the negative (-) battery terminal, and wait for at least 90 seconds.
  3. Measure the resistance of the wire harness side connector.

Standard resistance


  1. Release the activation prevention mechanism built into connector b (see page rs-37).
  2. Measure the resistance of the wire harness side connector.
