   Tester Display	Measurement Item	Range	Normal Condition	Diagnostic Note
   Lidar Detect Target Distance	Displays distance of the highest priority object which is detected by Lidar.	0 to 51.0 m	Distance between the vehicle and a preceding vehicle	When no preceding vehicle is detected, "0 m" (0 ft.) is displayed

   HINT: 

   If "0 m" (0 ft.) is displayed, the pre-collision city sensor (laser sensor) is malfunctioning.

   OK

   Distance displayed is within 3.0 m (9.84 ft.) +/- 0.5 m (1.64 ft.)

Result: 

OK
