OK, so one of my 4 bumper sensors failed and caused my entire system to fail. But now, with the #2 sensor replaced with an OEM part (and all 4 clicking normally, as best I can tell with my ear) - the system still doesn't work. The "OFF" light on my backup switch on the dash is still on and won't shut off.
So I check the fuse and it's fine.
What else can it be? I don't want to keep throwing parts at it and I know for certain that my #2 sensor was bad. I even disconnected the batteries, thinking it might reset the computer or something.
Any help would be appreciated.
Thanks.

The module is located in the passenger footwell up high, the speaker is attached to it and it is sold as one piece. It comes with a new pigtail harness also. The module is held in by plastic push nails. Water can get into the connnector and ruin the connection and module. Best bet is to hook up a scanner like AE to pinpoint the problem, if you get "No Response" from Park Aid" you probably need a module.
