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?

Aha, thanks, yes it could probably be the same on the European cars (made in Japan, not sure if it is the Japan made over there too or any local plant?).
I got the manual but it is useless, a thick book but it does not mention this at all, it hardly mention my type of head lights at all. Much more about the lamps with halogen high beam, this one I got is the top spec here except no sun roof.

Right now it seem more easy to rewire the drl with a new 12 V feed, but I hope for some other way.

 

[skarj]

Yes.

Thank you, I will try that and see if it works.

OK, I will need a second person to help me check, but since a lot of cars flashes me, I am rather sure it never works, they are "telling me" you don't have the lights on, since you get a ticket for it here, even in day light.

Here we have something, thanks! Do you happen to know if this apply on 2014 model too?

Yes, all years.

 

[skarj]

Yes, all years.

Then I will try that if I can't find anything else, and I guess just repeat the procedure will set it to ON, if it is set to OFF, if I understood it correctly?

 

[Mazdiod2]

I used the procedure to turn off my DRLs, but I intend to wire the fog lights to use as DRLs 'on demand' since Mazda hasn't provided us with that.

 

[Cooper1]

I usually just turn them to the "ON" position.

But you should do the same steps one more time to turn it back on again, right?
What I actually most of all would want is the low beam to be on at all time in the AUTO mode, what ever light or dark conditions there are, any setting to by-pass the light sensor, or to over ride it, that you or anyone know? That would solve it for me, I don't need the drl to function as long as low beam is always on, in the AUTO setting, so I don't need to switch the lights ON and OFF each time.

I find this Mazda way for drl to be very complicated/stupid, it is nearly impossible to check it yourself if the car need to be in D, no parking brake and as some say, need to be moving forward, why would they make it like this, to save energy? Why not just let the drl always be on if the car is running and there is day light? If it gets darker, low beam are automatically switched on. All other cars I got and had before with drl, kept it on at all times in bright conditions, and add the low beam in darker conditions together with the rear lights.

What do you put to ON? Lights? You mean low beam? That is possible, then you need to put it to OFF or AUTO when you turn off the cat, or the lights stay on, I don't want to need to turn anything each time, like I don't need to do in every other car
