Lexus NX: Operation Check
OPERATION CHECK
INITIAL CHECK
(a) Power switch on (IG) (intuitive parking assist system off).
(b) Intuitive parking assist system on and check an indication state of the vehicle mark.
OK:
The initial check is performed for approximately 5 seconds after the system turns on, and then the system switches to detection operation mode.
HINT:
- During the initial check, only malfunction detection is performed. Obstacle detection is not performed.
- A frozen indication is displayed if the ultrasonic sensor is frozen.
- If an open circuit occurs in an ultrasonic sensor circuit or a malfunction is detected in a sensor (ultrasonic sensor), an open circuit indication is displayed.
MALFUNCTION DISPLAY (MULTI-INFORMATION DISPLAY)
(a) Open circuit indication
(1) If there is an open circuit between the ultrasonic sensor and the clearance warning ECU assembly or a sensor is malfunctioning, the malfunction is displayed as shown in the illustration.
| *a | Open circuit indication |
(b) Frozen indication
(1) If a sensor is covered with foreign matter, such as mud or snow, the affected sensor is displayed as shown in the illustration.
| *a | Frozen indication |
HINT:
If a frozen indication is displayed, proceed to "Sensor Frozen Indication (Dirty or Frozen)".

(c) Communication malfunction indication
(1) When a CAN communication malfunction occurs between the hybrid vehicle control ECU, combination meter assembly, and clearance warning ECU assembly, they are displayed in the same way as shown in the illustration
| *a | Communication malfunction indication |
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 power switch on (IG).
(b) Turn the intuitive parking assist system 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 the front center sensor and the rear center sensor, use a wall or equivalent.
NOTICE:
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.
Front Corner Sensor and Rear Corner Sensor Detection Range
NOTICE:
The front corner sensor and rear corner sensor side view detection range (hatched area labeled (B)) represents the cross section of the top view detection range (A). The hatched area (B) does not represent the entire side view detection range.
Front Center Sensor Detection Range
Rear Center Sensor Detection Range 
(d) Front corner sensor display and buzzer operation check
(1) When the front corner ultrasonic sensor (front corner sensor) have detected an obstacle, check the displays and check that the buzzer sounds.
