Hi all,


I have a problem with front Right corner Parking Sensor ...it keeps sounding all the time and blinking on screen ...I replaced it twice with Original Denso brand new ,but it still sounding .. I checked front bumper cables and looks good ,


Any idea what's wrong with it???

 

Is there damage on the harness that connects them? Did the problem go away with a new sensor and then came back, or replacing the sensor never fixed it at all?

 

No the problem still there even when I replaced the sensor twice ,the sensor still sounding..


the harness looks no demage and to make sure I did disconnected the harness from top near Radiator and still sounding...

All other sensors work good and sounding only if something close to them ..



I checked the new sensors with other Ls430 and worked good..

I tried to find the ecu of parking assistant ,but could'n find it place to check all lines from ecu to front bumper ...



any suggestions or idea to find out the problem????

 

Good, but I need the diagram of wiring from ecu up to front sensors.

 

As known the sensor has 3 wires,which way and where to start checking do you suggest??
