Toyota Corolla (E120): Inspection procedure

1 Check side squib(rh) circuit(airbag sensor assy center – front seat airbag assy rh)

  1. Disconnect the negative (–) terminal cable from the battery, and wait at least for 90 seconds.
  2. disconnect the connectors between the front seat airbag assy (rh) and the airbag sensor assy center.
  3.  release the airbag activation prevention mechanism of the connector (on the airbag sensor assy center side) between the airbag sensor assy center and the front seat airbag assy (rh) .
  4.  for the connector (on the front seat airbag assy side) between the airbag sensor assy center and the front seat airbag assy (rh), measure the resistance between sfr+ and sfr–.

    Ok: resistance: 1 mw or higher

Sst 09843–18040

  1. Connect the the connector to the airbag sensor assy center.
  2.  connect the negative (–) terminal cable to the battery, and wait at least for 2 seconds.
  3.  turn the ignition switch to on, and wait at least for 20 seconds.
  4.  clear the dtc stored in memory .
  5.  turn the ignition switch to lock, and wait at least for 20 seconds.
  6.  turn the ignition switch to on, and wait at least for 20 seconds.
  7.  check the dtc .

    Ok: dtc b0110/43 is not output.

Hint

: codes other than code b0110/43 may be output at this time, but they are not relevant to this check.

    Circuit description
    When the ignition switch is turned on, battery positive voltage is applied to the coilwhich closes the contacts of the efi main relay (marked: efi) and supplies power to terminal +b of the ecm. This signal causes current to flow to the coil, closing the contacts of the efi relay and supplyin ...

    Inspection procedure
    Hint: start the inspection from step 1 in case of using the hand–held tester and start from step 2 in case of not using the hand–held tester. 1 Read value of hand–held tester(front speed sensor) Select the datalist mode on the hand–held tester.  check that there is no differe ...

    Overhaul
    1. Drain clutch fluid 2. Remove brake master cylinder sub–assy 3. Remove brake booster assy 4. Disconnect clutch reservoir tube Loosen the clip and disconnect the clutch reservoir tube from the clutch master cylinder assy. Hint: use a container to catch the fluid. 5. Disconnect ...
