Toyota Corolla Repair Manual: Inspection procedure

Hint

: start the inspection from step 1 in case of using the handheld tester and start from step 2 in case of not using the handheld tester.

1 Read value of handheld tester(front speed sensor)

  1. Select the datalist mode on the handheld tester.
  2.  check that there is no difference between the speed value output from the speed sensor displayed by the handheld tester and the speed value displayed by the speedometer when driving the vehicle.

    Ok: there is almost no difference in the displayed speed value.

Hint

: there is tolerance of 10 % in the speedometer indication.

2 Inspect front speed sensor

2 Inspect front speed sensor

  1. Remove the fender liner.
  2.  disconnect the speed sensor connector.
  3.  measure resistance between terminals 1 and 2 of the speed sensor connector.

    Ok: 0.6 2.5 Kw or 0.9 1.8 Kw at 20 c

  4.  measure resistance between each of terminals 1 and 2 of speed sensor connector and body ground.

    Ok: resistance: 1 mw or higher

Notice:

Notice

: check the speed sensor signal last

3 Check harness and connector(front speed sensor  skid control

3 Check harness and connector(front speed sensor skid control ecu)

  1. Check for open and short circuit in harness and connector between each front speed sensor and skid control ecu

4 Inspect speed sensor and sensor rotor serrations

4 Inspect speed sensor and sensor rotor serrations

(Reference) inspection using oscilloscope

(Reference) inspection using oscilloscope

  1.  connect the oscilloscope to the terminal fr+ fr and fl+ fl of the skid control ecu.
  2.  drive the vehicle at about 30 km/h (19 mph), and check the signal waveform.

Hint

:

5 Inspect front speed sensor installation

5 Inspect front speed sensor installation

  1. Check the speed sensor installation.

    Ok: the installation bolt is tightened properly and there is no clearance between the sensor and front steering knuckle.

    Torque: 8.0 Nvm (82 kgfcm, 71 in.Vlbf)

Notice:

Notice

: check the speed sensor signal last

6 Inspect speed sensor tip

6 Inspect speed sensor tip

  1. Remove the front speed sensor .
  2.  check the sensor tip.

    Ok: no scratches or foreign objects on the sensor tip.

Notice:

Notice

: check the speed sensor signal last

7 Inspect speed sensor rotor

7 Inspect speed sensor rotor

  1. Remove the front speed sensor rotor .
  2.  check the sensor rotor serrations.

    Ok: no scratches, missing teeth or foreign objects.

Hint

: if foreign matter is attached, remove it and after reassembling, check the output waveform.

Notice:

Notice

: check the speed sensor signal last

Check and replace brake actuator assy
