Hey all i'm new here but was wondering if anyone knew the best way to troubleshoot the parking assist system on a '04 Monterey. When I put it in drive the "off" light on the button comes on and I was told it has something to do with the rear sensors. Any thoughts?

On our 2006 Freestar there was a way to set the default on Parking Assist to ON....

Not sure how to do it, because the dealership did it before we left....

Parking assist should only work when the vehicle is in reverse, which would explain why it says "OFF" while in drive.

This is actually not true. It used to "sense" in the front while drive, such as to pull close in a parking spot. While in reverse both front and rear "sensed", such as parallel parking.

If I knew how to test a sensor on the bench for the proper resistance I'd be in good shape but I'm unsure what range I would need to be in. Anyone have any wiring diagrams or the ford manual for '04 to '08 Freestar/Monterey's?

I can't recall seeing any vehicles with a park front sensor except for a Lexus model my uncle bought a few months back, 600L or something similar. I find it interesting that they'd put sensors on the front of a mainstream vehicle. If I had them on my old car, they'd be long broken, as the wife likes to drive over obstacles while she LOOKS at them, lol.

Not to share stories or anything, but that plastic piece under the front end that's suppose to help with aerodynamics and push the air around to the sides of the vehicle. Well, anyway, the wife pulled up in front of a convenience store so I could run in to get directions. After I came back out, she was so busy looking for cars that could drive around her she drove over the median with the front end. I told her to shut the engine off so I could make sure we didn't bust the pan and lose any oil lol. However, the plastic piece was broken off!

MRSHO! I GOT YOU THERE! Us special Canadians can't buy Mercury vehicles locally. The only Freestar that was offered here was the 4.2L, we didn't even get the base 3.9L. I haven't seen any Limited versions at the dealer with the front park assist, but as mentioned, I've seen it on some higher lux cars. I saw a Mountaineer at the dealer a while back, and it had US spec instruments. A common complaint with journalists north of the border, is that the park assist sensors get covered in snow, and are generally useless in cold, snowy weather :( Not that it would help the wife any, but then again, she's still in the learning process.
