Toyota Corolla Repair Manual: Inspection procedure

1 Check wire harness(airbag sensor assy center front seat inner belt assy lh)

  1. Disconnect the negative () terminal cable from the battery, and wait at least for 90 seconds.
  2.  disconnect the connectors between the airbag sensor assy center and the front seat inner belt assy (lh).
  3.  for the connector (on the airbag sensor assy center side) between the airbag sensor assy center and the front seat inner belt assy (lh), measure the resistance between lbe+ and body ground.

    Ok: resistance: 1 mw or higher

2 Check wire harness(airbag sensor assy center  front seat inner

2 Check wire harness(airbag sensor assy center front seat inner belt assy lh)

  1. Connect the negative () terminal cable to the battery, and wait at least for 2 seconds.
  2.  turn the ignition switch to on.
  3.  for the connector (on the airbag sensor assy center side) between the airbag sensor assy center and the front seat inner belt assy (lh), measure the voltage between lbe+ and body ground.

    Ok: voltage: below 1 v

3 Check front seat inner belt assy lh

3 Check front seat inner belt assy lh

  1. Turn the ignition switch to lock.
  2.  disconnect the negative () terminal cable from the battery, and wait at least for 90 seconds.
  3.  connect the connector of the front seat inner belt assy (lh).
  4.  unlock the seat belt for the front drivers seat.
  5.  for the connector (on the airbag sensor assy center side), measure the resistance between lbe+ and body ground.

    Ok: resistance: 1.0 Kw 1.6 KΩ

4 Check front seat inner belt assy lh

4 Check front seat inner belt assy lh

  1. Lock the seat belt for the front drivers seat.
  2.  for the connector (on the airbag sensor assy center side), measure the resistance between lbe+ and body ground.

    Ok: resistance: 100 w 500 Ω

5 Check air bag sensor assy center

5 Check air bag sensor assy center

Sst 0984318040

  1. Connect 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 b0126/b0127/27 is not output.

Hint

: codes other than code b0126/b0127/27 may be output at this time, but they are not relevant to this check.

1. Inspect 4th gear thrust clearance Using a feeler gauge, measure the 4th gear thrust clearance. 4Th gear thrust clearance: 2. Inspect 3rd gear thrust clearance Using a dial indicator, measure the 3rd gear thrust clearance. 3Rd gear thrust clearance: 3. Inspect 4th gear ...

Overhaul
Hint: installation is in the reveres order of the removal. But the installation is indicated only when it has a point. In the rh side, work in the same procedure as in the lh side. 1. Remove rear armrest assy lh Using a screwdriver, remove the rear armrest. Hint: tape the s ...

Circuit description
A thermistor is built in the engine coolant temperature sensor and changes the resistance value according to the engine coolant temperature. The structure of the sensor and connection to the ecm is the same as those of the intake air temperature sensor. Hint: if the ecm detects the dtc ...
