CHECK HEADLAMP SYSTEM won’t go away!?

[ghstrptr]

Hello guys, I’m still new to this whole forum thing so sorry if I’m using this wrong. But I’m in desperate help to get the “Check Headlamp System” cleared. Quick story of how it came about.

I have a 2022 Raptor non-37 package. I upgraded front UCA, tie rods, Fox FRS 3.0, and on 37s now. No issues after I completed those modifications. Only thing since day 1 was I noticed the wipers didn’t work on the auto setting.

Then early this year in January Ford kept calling me about a recall (the one most, if not all Raptors got) and offered a mobile person to come to my house to do it. So I thought why not.

The day comes and the mobile guy said it’s mainly just a software update and change the motor for the wiper blade. So he went ahead and did that, also offered to warranty my battery since he noticed voltage was low.

After he did the programming the truck was turned off and restarted. Since the restart this message will pop up. It doesn’t pop up while driving, just at every single start up and you have to press OK to clear it. Then it doesn’t come back until next start up.

I brought to two of my local dealers, they said they will take care of it. A week later they tell me that is because of my aftermarket suspension, which I told them was bullshit. Never had any issues after changing the suspension. Only had this issue ever since they performed the recall.

I’ve tried ignoring it all this time but lately just getting annoyed of it. If anyone has sealed with this and remedied it please let me know. Thanks in advance.

Depending on what type of headlights you have, suspension can cause this. I’m not sure where the calibration is saved, but it is possible that a new calibration is required after programming and was not done. Yours may be something else, but here is one case of that: https://www.f150gen14.com/forum/thr...vel-and-35”-tires-installed.16291/post-387888

I appreciate the response. Hmmm similar but not quite the same. Mine just pops up at start up. Once I press ok to clear it, doesn’t come back no matter how hard I accelerate or brake. But next start up it’s there again.

I just bought the M26 Engineering ride height arms that are shorter to compensate for the new height and it didn't do anything still there. When my friend used Forscan he said it appears that it’s the driver side sensor that is not communicating. So I was thinking maybe I buy a new sensor (ML3Z-3C097-G) $135 and see if that’s the issue.

@ghstrptr Ivan, I just posted these on the other thread. Maybe worth a shot: https://www.f150gen14.com/forum/threads/check-headlamp-system-warning-message.13609/post-684605

@SilverPigeon Thanks for the post, I read it all and just tried 1&2 didn’t solve the issue. Will need my friend to help me with 3-5 and as for 6, I got a new Full Throttle AGM true battery last month for my lighting reasons but yeah new battery doesn’t solve it

That was going to be my next question. Did your friend tell you exactly what DTCs are present in Forscan? I’m assuming there is at least one if you’ve decided it is the driver side.

@JayRay If I remember correctly he explained to me that on Forscan it shows nothing for the driver side front level sensor. Which he said if it can’t even read it then probably the sensor itself might be damaged etc. Which is why I’m consider just spending $135 to buy a new sensor. BUT when I unplugged that level sensor, an additional message pops up stating “DRIVE CONTROL FAULT, Visit Dealer” so that makes me feel that it’s not the sensor

To be sure about the battery: did you do a BMS reset when you put the new one in? If not, do it to rule out battery issues completely.
