Finally if it wears through that wire causing no current flow and warning that "Everybody is gonna die of massive brake failure"
I just ran into the Reset Unsuccessful message after replacing the rear brake sensor (with sensors purchased from eBay and shipped from Hong Kong but look exactly the same as OEM ones), then I read that you could reset the sensor by shorting the two wires, so I got the old sensor, cut the wires, spliced them together and tried resetting: Then it changed to Reset Impossible! So I got the OEM sensors from the front that I had saved from a previous trip to the dealership where they unnecessarily replaced the sensors and used those, but still will not reset. Any ideas???
