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(skid control sensor)

  1. 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 skid control sensor

2 Inspect skid control sensor

  1. Disconnect the skid control sensor connector.
  2. measure resistance between terminals 1 and 2 of the skid control sensor connector.

    Ok: resistance: 2.2 Kw or less

  3. measure resistance between each of terminals 1 and 2 of skid control sensor connector and body ground.

    Ok: resistance: 1 mw or higher

Notice:

Notice

: check the speed sensor signal last

3 Check harness and connector(skid control sensor  skid

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

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

4 Inspect sensor and sensor rotor serrations

4 Inspect sensor and sensor rotor serrations

(Reference) inspection using oscilloscope

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

Hint

:

5 Inspect sensor installation

5 Inspect sensor installation

  1. Check the sensor installation.

    Ok: there is no clearance between the sensor and rear axle carrier.

Notice:

Notice

: check the speed sensor signal last

6 Inspect skid control sensor tip

6 Inspect skid control sensor tip

  1. Remove the skid control 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 sensor rotor

7 Inspect sensor rotor

  1. Check the sensor rotor serrations.

    Ok: no scratches, missing teeth or foreign objects.

Notice:

Notice

: check the speed sensor signal last

Check and replace brake actuator assy

Check and replace brake actuator assy

Notice

: do not reuse skid control sensor.
