OPERATION CHECK
1. MALFUNCTION DISPLAY (MULTI-INFORMATION DISPLAY)
(a) Open circuit indication
(1) If there is an open circuit between a No. 1 ultrasonic sensor and the clearance warning ECU assembly or a sensor is malfunctioning, the malfunction is displayed as shown in the illustration.
HINT:
If a sensor has an open circuit, check for DTCs and troubleshoot according to each inspection procedure (See page ).
(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.
HINT:
2. 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 ignition switch to ON.
(b) Turn the back sonar or clearance sonar switch assembly on.
(c) Detection range measurement:
(1) Move the shift lever according to the table below.
Measurement Area |
Shift Lever Position |
---|---|
Rear Corner |
R |
Rear Center |
(2) Move a 60 mm (2.36 in.) diameter pole near each sensor to measure its detection range. When measuring the longest-range detection of the front center sonar and the rear center sonar, use a wall or equivalent.
NOTICE:
These detection ranges are applicable when positioning the 60 mm (2.36 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.
NOTICE:
The No. 1 ultrasonic 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.
(d) Rear corner sonar display and buzzer operation check
(1) When the No. 1 ultrasonic sensors (rear corner sonar) have detected an obstacle, check the display and check that the buzzer sounds.
