So I have a 2007 gs 350 awd and every time I come to a stop and have my parking sensors on it shows up with the red bar like it's right up against something. What can I do to figure out which sensor is bad? All my connections have been checked and have been cleaned already and still the problem exist....what next?

 

Any advice will help! Give me some feedback please

 

option 1: go to dealership, wait 2 hours and pay $100 for diagnostic
option 2: Buy a mini-VCI cable from ebay for about $30, install weird Chinese software on your computer spending about 3 hours trying to figure out how to make it work on anything other than 32bit windows XP (it does work eventually), plug into OBD plug on car and check status of the sensors. The bad sensor will either show no reading or will be stuck.

The thing about option 2 is that after the initial setup mess it actually is a pretty useful tool to even change dealer set options on the car.

 

Ok I actually bought the obd scanner yesterday bc I want to change some of the dealer set options without having to take it to lexus so now it's a bonus in that it can pick up on signals from my parking sensors too! Thanks for the info. Have u used this software and scanner personally?

 

Mini vci package I meant to say.
