Technical Background
The Rain/Light Recognition Sensor -G397- is light sensitive and is responsive to change in ultra violet (UV) rays.A change in light may cause the
windshield wipers to do a single swipe, which is known as a "Tunnel Wipe " function.When the rain/light recognition sensor -G397- detects a light to
dark transition when the rain sensor function is turned ON, one wipe cycle will be performed if the elapsed time after the previous wipe cycle is greater
than 15 seconds.This communication is received via the Local Interconnect Network (LIN) data bus.The communication for the rain/light recognition
sensor takes place over a LIN bus.
The light sensors and rain sensors are always active when terminal 15 is ON.
The Function Can Not be coded off.
