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 on–off.

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
