2012-2015 rius: Pre collision Sensor Radar 88210-47061 These are hard to find. If you do have one I’ll gladly buy it from you provided it’s not been damaged. These are sensitive units. Impact and dropping can make them defective.
I've been investigating the use of one from another vehicle. I'm hoping to find one with the same plug without the need to do any special wiring to make it work. Will let you know when I find one! The Corolla is close tho....
