Automatic headlight keeps going up & down. Bad AFS motor? Disable it

Something in the AFS system went crazy and my left headlight beam kept going up and down. The tilt adjustment motor would not stop running and was getting very hot.

[@leanderjackiegrogan]

Thanks for the video. This is helpful. The part is actually 253C rather than 235C ... no problem.

[@ostapbender952]

Good explanation thanks

[@EdBwoy]

Thank you, much appreciated

[@BarziHSaeed]

Does ASF has anything to do with Front Radar ? My radar is bad but adaptive headlight doesn’t work Mazda CX5

[@user-xp2fr4lq8u]

Can you tell me how to change Infiniti m56 headlight Q70 and activate ASF?

[@joshuagrube5849]

Hey Edbwoy. I enjoy your passion for the m45. I really enjoy the 2003 I bought a back in September. I was wondering if you had any advice on performance upgrades for this car? Also I am looking for the gps monitor because mine works intermittently. Do you have anything for sale ATM?

[@EdBwoy]

Thanks Joshua. Unfortunately I don't have any 03 parts. For upgrades, not much really. I heard that the cars can now be tuned by UpRev, but it would be best to confirm with them (www.uprev.com/secure/) Otherwise, it is a pretty optimized platform and maybe you can do things to make it sound louder (exhaust work) or accelerate faster (differential swap)

[@joshuagrube5849]

@@EdBwoy Thanks for replying. I will check the UpRev upgrade. I was curious about the differential because I do a lot of highway driving and it tachs like 3k at 80 mph and I would like it to be more in the low 2's. What differential can be swapped into the m45?

[@EdBwoy]

In that case, you wanna go the other way. An FX35 or Fx45 differential might be great for acceleration but will suck for cruising. The differential of a 2002 (only that year) Infiniti Q45 might be better for cruising, but will give up some acceleration. forums.nicoclub.com/post6785260.html#p6785204

Have you experienced any buzzing sound from around the passenger headlight section? Specifically the area where you can't access the AFS switch like you would on the driver side. I keep getting a buzzing sound there but only when its winter and extremely cold. I cant find explanation for that.

[@EdBwoy]

No, I haven't, but I would follow the troubleshooting in the video. Switch off, harness unplugged etc. There is another video I once saw on youtube on how to adjust the motors if they were grinding. Maybe that would help.

[@rodword]

@@EdBwoy perfect. I will search for that video because winter is coming and I hate hearing that noise when it's cold.

[@sdwalton33]

I do miss having AFS on my M56S. Great job explaining it. You should take up graphical design with those skills 🤣🤣 Always make sure the hood is latched too.. Oops! 😲 I would think that the load sensor is the problem, since the motor is working. Only other thing I can think of is the travel stop switch in the light motor has crapped out. Requiring full disassembly of the light and Ohm meter to check. Good luck!

[@EdBwoy]

Hahahaha. I try with the sketching. Do you visit the nicoclub forums by chance? I have seen some impressive animators on KZbin, so with the right software (and available time) I'm sure I could tell a good story.

[@EdBwoy]

And reading your comment, I'm thinking I should have done one more test - Jack up the rear to see if both headlights go up. That would confirm if the right side tilt motor was also functional. 1. If both went up, it's definitely an issue with the left motor. 2. If the right one does not go up, then the height sensor might be the issue tweaking and sending signal to both lights to constantly adjust. The up/down tilt is actually just considered auto-aiming, the AFS is the sideways swivel stuff. But both called Active AFS as a general term - I could have gone into more depth, but it was easier to stop the headlight motor since the new owner was taking delivery the next day. *There might be a part 2 to this*

@@EdBwoy I consider NICOclub my go to for Infiniti help. All the available info is priceless for stuff other owners have tried and figured out what's best or easiest. You're a close second 😉 Been working on cars and aircraft since I could walk and still feel like a novice. The wife says I treat them like girlfriends sometimes!

Man I got 2010 m35x and I got hit on passnager bought used light match it with serial # but afs keeps flashing help

[@jaybusiness5901]

My headlights seem as thought they are pointing down could this be because of a faulty system? I can barely see the road but when you stand in front of the car the headlights seem bright.

[@EdBwoy]

If your car is lowered enough the headlights will react accordingly. Do they still swivel? You can test the up-down aiming to know if the motors still work. It's unlikely for both to randomly fail and face down

[@jaybusiness5901]

They still swivel but I can barely see out in front of me. The fog lights shine farther than the headlights.

[@EdBwoy]

@@jaybusiness5901 is the car lowered? Park in front of a wall and observe the headlights, especially if you jack the rear

[@jaybusiness5901]

Car isn’t lowered. In front of a wall the cut off line is visible but from a short distance it becomes faint.

[@EdBwoy]

@@jaybusiness5901 test by lifting the rear.

[@benjamincollins6553]

Its like my right is all the way right and my left is all the way left 🤔🤔 driving me crazy

[@bluescorpion17]

Where can i find the AFS & the fuse in Toyota camry 2019 if you know?

[@EdBwoy]

Sorry, I'm not familiar with those. However, I know that Toyota usually includes a fuse layout diagram in their owners manuals. That might be a place to start.

I Want To Change My Headlight Bulbs From HID To LED Does The Front Bumper Has To Come Off To Remove The Headlight Bulbs?

[@EdBwoy]

No. You can access them through the wheel wells

[@fbodyws6ta]

@@EdBwoy i Value your opinion i have the leds in the fog lights and it is a lot brighter than the HID which one do you prefer the hid or led?

[@EdBwoy]

@@fbodyws6ta actually neither one for me. I like factory lighting for these cars because they give proper light output. Aftermarket LEDs or HIDs might look bright when you take pictures, but sometimes they don't light up the road well enough. Or they just blind oncoming cars. I can't advise you on either type for your fog lights.

[@jamesofalltrades4359]

I can be Parked and my right light will not turn right. My left light turns when I’m parked. Before I got my car the right side was hit. I’m assuming the motor is bad in my right headlight.

[@EdBwoy]

Yeah, the system seems all goofy fam. When in *park* neither one of them should move. When *stopped and in D* only the right one should move

[@jamesofalltrades4359]

Ok so last night when I got home I tested it. My left only moves when I’m driving. The right does turn. This morning there is a brand new m35 at the junkyard if I see any headlights I will let you know. I buy things I don’t need just to have extra

[@EdBwoy]

@@jamesofalltrades4359 alright, keep me updated

[@jamesofalltrades4359]

Hey bro I did find a passenger headlight but it was all cracked up. I thought you could pull that motor lol. I quickly realized you can’t lol. I will keep my eye open

@@jamesofalltrades4359 thanks for checking man. So far, no complaints, so I'll just put this matter to rest for now

I have afs system error for q50s 2019 red sport how do i trun that off ?

[@LuisC202]

I have the same problem on a 2017. Did you figure it out?

[@muhammadsuhaibnazar5348]

My headlights are pointing down. What should I do?

[@EdBwoy]

Is your car lowered?

[@muhammadsuhaibnazar5348]

Well, it doesn't look like it, but I wouldn't know exactly how to check.. I recently bought it. Previous owner said he had LED lights installed.. I read/heard how you said you only recommend the factory bulbs. Is there a way I can adjust these ones to the right level? I believe it's the same headlight assembly, just aftermarket bulbs installed.

[@EdBwoy]

@@muhammadsuhaibnazar5348 if the tires (especially rear) are sunken under the wheel arch, the car would try to correct that. For both to point down, I'm guessing their common sensor is getting an off signal or the AFS module for some reason went bad. You can try jacking the rear end with the headlights shining against a wall to see if they start correcting upwards

[@muhammadsuhaibnazar5348]

So, the wheels don't seem to be sunken into the wheel arches. There's about an inch and half gap. I looked under the rear end, but I couldn't spot anywhere to place my jack to lift the car. So, I saw these plastic gears behind each headlight, under the hood, and marked them. Then, I checked to see if they had moved, comparing them against having the car on the inclined ramp in front of my garage and parking it on level surface inside the garage. The didn't move at all.

[@EdBwoy]

@@muhammadsuhaibnazar5348 so maybe the AFS module is bad? Does the front end look like it has been repaired after a collision?
