sensor lost communication

Hey yall, if you ever encouter this problem : Parking help not available. (hope this is it in english) and you go in your service mode to check your USS (bumper sensors) and have one that says "sensor lost communication" and it's red. Here what i did to find and correct the problem.
1- mine was in the back, so removed the rear bumper, but only half way - the bottom was still snaped in and I let it rest on a box so it doesn't go to low.
2 -Undo the sensor from the bumper and take a ohmmètre to test the continuity of the wire. I started from the sensor, but Murphy was with me and the wire was rusted/oxydated near the big connector at the right side inside the bumper. :)
3 - repair the wire, only had a yellow shrink so, it's yellow now instead of purple, reconnect everything back, let it sit for a while and check the service mode and voila.
