Toyota Corolla Repair Manual: Inspection procedure

1 Check operation(overdrive)

  1. Drive the vehicle after the engine warms up.
  2.  check that overdrive on e off occurs by an operation of the o/d switch onoff.

2 Inspect terminal voltage(od)

2 Inspect terminal voltage(od)

  1. Remove the cruise control ecu assy with the connector still connected.
  2.  turn the ignition switch to on.
  3.  disconnect the cruise control ecu assy connector.
  4.  measure voltage between terminal 14 (od) of harness side connector of cruise control ecu assy and body ground.

    Ok: voltage: 10 14 v

3 Inspect terminal voltage(ect)

3 Inspect terminal voltage(ect)

  1. Connect the cruise control ecu assy connector.
  2.  perform the test drive after engine warms up.
  3.  check voltage between terminal 6 (ect) of cruise control ecu assy connector and body ground when o/d switch is on and off.

    Ok:

4 Check harness and connector(between cruise control ecu assy

Mechanical system tests
1. Perform mechanical system tests Measure the stall speed. The object of this test is to check the overall performance of the transaxle and engine by measuring the stall speeds in the d and r positions. Notice: Do the test at normal operating atf temperature 50 to 80 c (122 to ...

Overhaul
Hint: overhaul the rh side by the same procedure as the lh side. 1. Remove front wheel 2. Drain brake fluid Notice: wash the brake fluid off immediately if it comes into contact with any painted surface. 3. Remove front disc brake cylinder subassy Remove the union bolt and gasket fr ...

Inspection procedure
Hint: if dtcs besides misfire are memorized simultaneously, first perform the troubleshooting for them. Read freeze frame data using the hand-held tester or the obd ii scan tool. Freeze frame data records the engine conditions when a malfunction is detected. When troubleshooting, it ...
