DETECTION RANGE MEASUREMENT AND DISPLAY INSPECTION
NOTICE:
The following measurement and inspection will be performed 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.
(a) Turn the engine switch on (IG).
(b) Turn the static objects function is on.
(c) Detection range measurement:
(1) Move the shift lever according to the table below.
| Measurement Area | Shift Lever Position |
| Front Corner Sensor (front corner ultrasonic sensor) | In any position other than P |
| Front Center Sensor (front center ultrasonic sensor) | In any position other than P or R |
| Rear Corner Sensor (rear corner ultrasonic sensor) | R |
| Rear Center Sensor (rear center ultrasonic sensor) |
(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 a front center sensor or rear center sensor, use a wall or equivalent.
NOTICE:
These detection ranges are applicable when the 60 mm (2.4 in.) diameter pole is positioned 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.
