Hello

I have been browsing the forums for a long time . I have always been able to find a solution thanks to the amazing community . However this time around I'm stuck

Background:

Driving like crazy in the desert and hit the front of truck-bumper (ford f150 2020). There was no physical damage .

Driving home , all was working great , that include adaptive cruise control. Until someone came into my lane and all of the sudden the truck brakes and throw and error on the screen that my pre-collision assist not available. I checked my DTC and got horizontal sensor is not aligned (Code: B142E - Forward Looking Sensor Horizontal Alignment). I have seen few manuals which indicated that a vertical sensor alignment requires a physical adjustment , where horizontal sensor alignment requires a calibration.

I removed the plastic part of the bumper to access the sensor module where there was also no physical damage as the bracket holding the sensor and the sensor itself seems to be fine. I have also pulled the pid and more specifically the Align_off". See screen shot.

Issue:

I am connecting to the my truck thru the recommended obd reader from vlinker. I have been using it for long time and it is great and fast by the way.

I attempted to do a cruise control calibration from my phone as well as laptop. In both situations the calibration is stuck at 0 percent regardless of how long I drive to recalibrate. I have also tried to reset the module before calibrating it but still no success.

I would appreciate any help.

That is rather interesting. I am thinking @FordTechOne may be able to provide some usable insight.

@smurfslayer thanks . I tried thinkdiag 2, which also provide service level diagnosis , I couldn't recalibrate using it .

I can see the module , I can reset it but cannot recalibrate . Not sure if I should give up and bite the bullet .... I just wish I can just have cruise control lol.

I had a long drive today and it sucked

Sounds like your scan tool may not have the capability of running the calibration routine. Likely you will need Ford IDS.

Just as an update:

Until I figure out what's wrong with the sensor, I was able to disable adaptive cruise control while maintaining regular cruise control .

I used forscan thru IPC module and changed the attached settings in the screen shot.

Thanks

You should be able to do that in the truck instrument cluster I believe.

Just to update this post.

I accessed the radar behind the plastic panel on the bumper. There are essentially 3 bolts holding it. One on top and two at the bottom. The one on top manges the vertical alignment. The two at the bottom manages the horizontal movement.

I focused on the bottom two by tighting one and loosening the other. Trial and error until I got the ALIGN_OFF to show - 1. This would work as long as that PID shows a number between +3 or -3.

Used the calibration process again until it worked

Biggest issue is that the number will only reflect the actual value once a calibration is done.

Good luck
