DRL in headlights not working

[skarj]

Hello,

My problem is the drl in the healights, they doesn't work, neither right or left side. Light mode "AUTO", and I have the headlights with bixenon, no halogen high beam.

Bulbs are OK on the 13 W standard lights that is drl.

Any guesses what is wrong? Can't find any faulty fuse, so far no chance to check if I got 12 V to the HB3 connector. Found a video online mention D (drive) need to be in, I tried, still no light.

My guess is these should light up i n day light, and if the day light get dark enough the Xenon low beam lights up automatically, but on my car nothing lights up in the front if the mode "AUTO" is set and it is day light condition, when it gets darker, low beam starts.

Is your parking brake off when you are looking/testing?

 

[skarj]

Not every time, but I am quite sure that it been off most of the time, it is a manual parking brake, but you mean it need to not be engaged (parking brake) to set the drl to ON?
Last time I was on my own and with D, I had the parking brake active (handle pulled) so I could stand infront of the car.
So it need to be in "AUTO", in D and manual parking brake OFF? Anything mote too if this is correct?

Did you buy your car new? Perhaps previous owner disabled DRLs.

 

[skarj]

No I didn't buy it new, but I doubt that it was disabled, since it's illegal to drive it without any front light here (Sweden), and in "AUTO" nothing is on, hence illegal, so I can't see the point of disable it and lose the function of use "AUTO" as light setting.
But any idea how they did it if anyone would have done it, coding?

It's a convulated sequence of operations, push this button, hold this button, etc. Some have had success and some weren't able to get it to work and it reportedly does not work on Canadian CX5s. So probably doesn't work on Euro CX5s either.

I suggest checking the owner's manual for your model year and country, see what it has to say about DRLs.

Yes.

DRL only runs when the car is in motion. You'll need to drive up to a glass storefront to confirm functionality.

I had to do this a few weeks ago. Here is the process to "disable DRL".

I just pulled the drl relay, flipped it over and taped it to the relays next to it inside the fuse box. The lights are now stalk controlled just like i like them. auto works as before and wife can just use parking lights for drl if she feels the need and the relay is right where it was if ever needed without searching for it.

Have you tried Mazda’s official instruction to disable the DRLs?
