Hi, Just wondered if anyone knows how to repair the front parking sensor and where it is located. A few years ago while driving the sensor suddenly started to sound with a continuous beeping. The rear one works fine but I have to turn off the sensor with the switch on the dash. Its just one of a few silly little problems but on the off chance one of my fellow owners of the fabulous RX300 might have come across this and have the solution I would be most grateful if you would share it with me. While I am on here perhaps it might help anyone who has the problem of the ABS light coming on and, knowing how complicated it is to cure. I am about to put my car in the hands of a mechanic who is confident he has found the cause He says it is something to do with the heated windscreen wiring loom and module connections being corroded. Hope it is not just another theory. I will let you know the results.

 

Regards.

Front parking sensors were never a factory fit on the RX300 and 400h, but were a dealer option. As such I don't think there'll be a wiring diagram or anything in the workshop manual for them.

The windscreen deicer wiring and the brake fluid level switch wiring are together in the same harness so he may well be on to something there.

Good luck :thumbsup:

Thanks Herbie, trouble is I won't know what I am looking for, never mind I can live without it, rear one still works. I was a little pessimistic about his diagnosis because in my search for the problem I read so many where they had been trial and error, very expensive being a Lexus, just hope he is right. They are very good in this line according to the reviews and he was really good when he did the original diagnostic test. he told me he wouldn't charge me if he couldn't find the answer and because they specialise with BMW and Mercedes they didn't have the wiring diagram for my car he kept his word. He wants the car for at least three hours so got to trust someone. Thanks for your response, most helpful.

 

Regards

    1. 1. If you were to consider buying a Hybrid model over 5 years old, would you be worried about the reliability of the Hybrid system?


      • Not really as Hybrid systems are always reliable
      • Not if it had a Manufacturers Warranty on the Hybrid system
      • I would not buy a Hybrid model over 5 years old
