Backup camera lens
Okay, so I'm approaching the end of week #5 of owning this car.

So far, it's spent more weekends in the shop than my driveway, and is currently still in the shop for the P0420. (I still think that the dealer messed up dropping the transmission for the clutch replacement.)

Anyway, not that I've spent that much time driving it, but there are some things that have been bugging me, and I'd like to get to.

The backup camera is super hazy. At first I thought that it was just a dirty lens, but after cleaning it, it's still hazy. I didn't see anything on the backup camera here, but I figure that I'll give it a shot with some polish, and an anti-fog treatment. I think that I have a headlight restore kit around somewhere that has polish and an anti-condensation coating. Anyone know of any gotchas when working around the camera?

Okay, here's a slightly more technical question, if anyone has an answer.

The car is a 2012 Titanium HB with the Ford Mytouch 8" display

Is is possible to tap into the backup camera for my dashcam? I can input a composite signal into the dashcam, if I can tap into it.

I know that some of these cameras are not meant for high duty cycle, I had a backup camera kit before which had a sepcific warning not to use it for dashcam usage, as being always on would damage the camera. (Crappy design, then, IMO.)

I actually used that camera in the left hand mirror assembly of a right-hand drive JDM car, and it comes on with the left signal light to show oncoming traffic when making left turns. I put a small corrective lens in to protect it from the elements and to narrow the wide viewing angle. The monitor could flip the image so that it wasn't mirrored.

Anyway, my dash camera came with a rear view camera, and a trigger wire so that it could be used as a backup camera, but I'd rather not mount a second camera if it isn't necessary. I do want to record the rear camera, as there are far too many nutty drivers around here.

if not mistaken, to put a oem cam in all you need is the cam and wire harness... the harness is like $30? the cam is like 200, but a quick run to the local pick-n-pull should be much cheaper. then just set in bcm/ipc that the car has a a rear cam

starting to dig this PNP style of newer fords

I have the OEM cam already, the lens is pretty hazy, so it needs a good cleaning, maybe a polish, but it's already there.

It'd be nice if I could use it for the dash camera, as in a complete non-OEM application, if I can tap into a usable signal from it. It occurs to me that it may only be turned on when the car is in reverse (Would make sense, really) and may do things like take over the screen if I turn it on with the dash camera. I'm sure that I could do things to not let the system know that it's turned on, but I do worry about duty cycle.

I'll probably end up installing the rear camera that came with the dash cam along the top of the rear window at the top of the wiper arc. if I do that I won't need the weatherproof casing, so I'll probably fabricate a new housing for it, maybe use my 3D printer. It won't be as useful as a backup camera that way, but since I have the factory one, that's probably okay.

My camera also has a battery-backed feature where it will come on based on an internal shock sensor, so it could catch someone hitting the car while it's parked. The higher vantage point might be more useful for that.

Well, so far, it's not like I've been driving the car anyway. Of (to date) 40 days of owning this Focus, I've spent 24 days driving either a rental or a service loaner. Currently driving a rental, since my car has been at the dealership service department for the past week.

The 10.4" tesla-style ebay screens have a separate harness that leads from the back-up cam factory harness to the head unit itself so I would assume that you can tap into them.

When I pulled apart my APIM the backup camera just plugged into the back of the unit. I can't remember at this point if it was USB or composite. You'll have to pull your APIM out and take a look.

At this point, I'm not sure, but I think that this car just hates me.

Yesterday (Yes, on April 1, go figure.) the backup camera stopped working at all.

So maybe something just got pulled loose, or a connector failed, but I've had the car back from the dealer for 4 days, I think. Pretty sure that I'll do the front-end diagnostics on this, unless this comes under the extended warranty on the APIM, in which case... WTF, Ford?

SupraGuy 04-02-2019 01:07 PM

So at this point, I guess I have to diagnose the reverse camera. I can think of a few possibilities:

1. The connection to the APIM is loose. If this is the case, then I have to pull the APIM and check that all connections are secure and tight. This shouldn't be too bad, and the fix is pretty much the same as checking it.

2. The connection at the camera is loose. Maybe I closed the liftgate too hard or something.

3. The wiring at the liftgate hinge has failed from repeated stress of opening/closing.

4. The camera itself is fubar.

2-4 all involve taking all of the trim off of the liftgate, with 3 maybe requiring pulling down a part of the headliner.

I wonder if I should inquire if this is/might be part of what gets covered with the APIM warranty extension from 12M02

Just once, I'd like to be able to get through a tank of gas without this car needing to be in the shop. So far, I've brought it back to the dealership more often than I've brought it to the gas pumps.

IIRC all the wire harness are under the trim not the head liner, check my posts I posted a cad drawing of the harnesses and the part numbers
