Toyota Corolla (E120): Inspection procedure

1 Inspect cruise control actuator assy

  1. Turn the ignition switch to off.
  2.  disconnect the cruise control actuator assy connector.
  3.  measure the resistance between terminals 1 (mo) and 2 (mc) of cruise control actuator assy.

Hint

: if control plate position is fully opened or fully closed, resistance cannot be measured.

Ok: resistance: more than 4.2 Ω

2 Check harness and connector(between cruise control ecu assy

2 Check harness and connector(between cruise control ecu assy and cruise control actuator assy)

  1. Check for open and short circuit in harness and connector between cruise control ecu assy and cruise control actuator assy (actuator motor)

Check and replace cruise control ecu assy

    Adjusting the set speed
    To change the set speed, operate the lever until the desired set speed is obtained. 1 Increases the speed 2 Decreases the speed Fine adjustment: Momentarily move the lever in the desired direction. Large adjustment: Hold the lever in the desired direction. The set speed will be increased or dec ...

    Circuit description
    The actuator motor is operated by signals from the cruise control ecu assy. Acceleration and deceleration signals are transmitted by changes in the duty ratio (see below). Duty ratio: the duty ratio is the ratio of the period of continuity in one cycle. For example, if a is the period of co ...
