Hello everybody

I have problem with my IS 300H '14 with parking sensors. I got warning "Clean park sonar" though all sensors are clean (i cleaned with toothbrush and WD40). Do you have any ideas how to check which sonar is damaged or how it repaired?

Best regards

 

A toothbrush and wd40 couldn't be two worse things to clean something on a car with... Honestly I wouldn't be surprised if you caused more damage.

 

Local auto shop could not get into Lexus proprietary info so had to go to Lexus.

lexus ran diagnostics test and it came back that front sensor was not working.

replaced by Lexus $804.00.

 

+1, for future reference, just use Quick Detailer type spray and a soft towel or just wash the car normally.

Even when my car is filthy, I never see such a warning, so I would suspect a fault somewhere with the sensor or downstream of it.
