Gen4 Headlight Auto Levelling Initiallisation

 complex solution to a problem that never existed

Soeley,

The auto-leveling is a regulatory requirement in many jurisdictions.  That means that a warning light to indicate failure of the system is also a requirement.  You usually don't get one without the other.

So, if your dash isn't showing a warning light for the failure of the headlight adjusters, that's a puzzle.  You can see the warning light on the preignition all-lights status check.  If your computer detects a failure in the system, the light would come on again after starting.

Maybe before mechanically altering the system again (potentially), do some "sanity checking" to make sure the problem is really what you think it is.  For example, when you say the system is not working, you don't mention what tests you might have done-- did you change the load in the car and the headlights did not react?  Get the fat neighbor from over the road to stand on the tow ball, etc?

I have no particular expertise, as my Jimny has a manual HL adjustment wheel.  But the facts that 1) you don't mention a dashboard warning light and 2) your dealer says the system checks out on the computer, together suggest that your Jimny at least thinks everything is working as it should.  Try the tests above, before you dive into it.

And if the tests show the car isn't reacting to changes in load (the purpose of self-leveling HL) only then start looking for problems, e.g. did the axle link slip off again somehow, can it be set in a different orientation that activates the HL motors, does your multimeter show the sensor values reacting appropriately, is there voltage at the sensor and HL motors, etc.

I don't think there will be a deep mystery here, as there just aren't that many parts to go wrong.  Good luck.

Edit: and if in the end you confirm that it must just need a recalibration, I would vote for taking it to your local quality independent shop, where they may have more customer focus...

WHat I struggle to understand is why the dealer did not fix the problem.

 

Yes, I am a bit annoyed about that, they didn't even try to suggest anything or say they will try an look into it and get back to me

Thanks for your input.

The dash warning light does light up on the Pre-Ignition test, so I know the light is working, but with engine running and lights on, the warning light is not illuminated.

I knew the auto levelling wasn't working straight away, as normally when the headlights are switched on, they do an initial up/down movement and now they don't.

It is sensitive enough to see the headlights auto level just by getting in and out of the car or just opening the rear door, as the shift in weight of the spare tyre activates it.

I will get back under this weekend and have another look at it.

Hi all. I ran into the exact same issue. Have you solved it? From what instructions pictures from the first message? How to properly adapt the headlight corrector through the SDT?
Thank you!

Hi, no I still haven't solved it. I just made sure that when fully loaded the headlights are not dazzling, I adjusted on the back of the headlights. It doesn't seem to be tested in our UK MOT, at least it wasn't picked  up on.

I would like to find a good independent Suzuki specialist to get it sorted.

when I bought the car from the previous owner, the corrector worked for me, but incorrectly. when the load was increased, it lowered the light too much, so that at full load it shone very close. I came to the dealer to adapt the height sensor, but after that the corrector stopped working completely. We may have done something wrong, since the specialist at the dealer did it for the first time, and I'm looking for at least a detailed instruction. you had screenshots from somewhere in the first message, can you post the full text of the instructions for calibrating the headlights?
