Operation Check [03/2019 - ]

  1. Self-diagnosis System 
    1. If the clearance warning ECU assembly detects that an ultrasonic sensor is malfunctioning, a malfunction indication is displayed on the combination meter assembly.

  2. DETECTION RANGE MEASUREMENT AND DISPLAY INSPECTION 
    NOTE:

    Perform the following measurement and inspection with the shift lever in a position other than P. Be sure to apply the parking lever and depress the brake pedal firmly to prevent the vehicle from moving.

    1. Turn the engine switch on (IG).
    2. Turn the back sonar or clearance sonar switch assembly on.
    3. Detection range measurement:
      1. Move the shift lever according to the table below.
        Measurement Area Shift Lever Position
        Front Corner In any position other than P
        Rear Corner R
        Rear Center
      2. Move a 60 mm (2.4 in.) diameter pole near each sensor to measure its detection range. When measuring the longest-range detection of the rear center sonar, use a wall or equivalent.
        NOTE:

        These detection ranges are applicable when positioning the 60 mm (2.4 in.) diameter pole parallel or perpendicular to the ground. The detection range varies depending on the measuring method and type of obstacle (such as walls).

        HINT: 

        Have an assistant move the pole.
