GMC to Ford

My glass shop has been in business for 21 years. They handle all the glass claims for GM, VW, Hyundai, Dodge, Kia, Toyota and two Ford dealers in my area. The dealerships are all owned by the same family except for one. Supposedly, my windshield is the first 2015 + Ford to experience any problems.

Reading your first post it sounds (to me) like this "family" is not completely on the same page. I could spend 20 minutes typing all the reasons they don't know what they're doing.

They've also had problems, "They learned that disconnecting the wires caused problems." Then tells you it needs recalibrated and the Master Tech isn't sure?

Obviously JMO but they need to figure it out or the problem will become more widespread as more windshields are replaced. YOU should not have to deal with this issue.

@iDrive ... I would tend to agree. It sounds like your installer didn't do the job right either. Based upon Great White's post, the service manual requires recalibration every time the mirror housing is removed and reinstalled. I believe this will become a bigger problem in the future as more of the newer windshields are replaced and the installers fail to complete the job correctly. It sounds like your installer got lucky and did not disturb the camera enough to cause problems.

On an interesting note, my rain sensing wipers started partially working today. The two lowest positions on the switch after OFF still do not trigger the wipers to come ON.

"But you may not as the "brain" for lane detection is in the mirror housing itself and uplugging it from the truck's power may cause the calibration to be lost."

As I mentioned, my guy does them himself - 25 yrs -blah blah.... Other company's have tech's that may well have never replaced one of these or at the very least are not that experienced. They truly have no clue what they're up against.

I would be curious to know how many folks have had their recalibration done after their windshield replacement.

To be clear, I was only guessing the lane mirror might loose it's calibration. I don't know for certain either way. But as I mentioned, the processor is in the mirror housing on the board that handles auto-dimming and other mirror functions. So unplugging it from power would likely cause it to loose volatile memory, which is where I would assume the calibration would be stored. Or maybe not, as a battery change coudl wipe it out also and there's no "re-calibration" when you change a battery. Would seem to be a silly designed system if you had to do that every time you lost power.

Since I'm installing a lane keeping mirror soon in my truck (waiting for it to show up), I can unplug it once I have calibrated it and see if it looses it's calibration.

I've got IDS so it's not a big deal for me if I loose the calibration. I'll just run another calibration routine.

Assuming I can get it retrofitted properly in the first place that is....

Thanks to @tmcolegr for providing the following information from the service procedures.

Camera Alignment
Camera alignment is required for the lane keeping alert and lane keeping aid to function correctly. The procedure is initiated using the diagnostic scan tool and requires about 10 minutes of driving above 40 mph (64 km/h) to complete. NOTE: The alignment completion is indicated on the diagnostic scan tool. If the alignment is unsuccessful, check the interior mirror for proper installation.

NOTE: The FRONT CAMERA MALFUNCTION - SERVICE REQUIRED message in the IPC disappears when the system is aligned.

The IPMA camera alignment procedure should be performed when any of the following occur:

-Windshield replacement
-Change in tire size
-Suspension repair or alignment
-Front air bag deployment
-Interior mirror replacement

I've leveled (ICON) change tires (have two sets of rims that have different size tires on them) at least twice a year and have had my windshield replaced.

Have never had an issue with the IPMA camera or any features.

As I said before "I would be curious to know how many folks have had their recalibration done after their windshield replacement" and tire size change, level or lift.

Not trying to be argumentative but IMO more times than not, it's not needed.

I hope they get your issues straitened out. As I said before, you shouldn't have to deal with it. Also wondering what the dealership is going to charge for this calibration when needed.

Four hours at the dealer to recalibrate and clear all codes on my lane keeping system (45 minutes of work), and it works as designed. The rain sensor processor seems to be in a learning mode. It did not work for the first two days, started working erratically for several days and finally returned to normal today.

My service writer and glass shop were not aware of the recalibration requirement, but the senior master technician had performed several.
