Testing OEM DRLs

Recommended Posts

I just purchased the OEM DRLs to add to my 2017 MKX. Does anyone know of a procedure to test these by have them illuminate before they are installed?

 

There are 6-pins on the DRL labeled

1 - DRL LED ANODE (+)

2 - LED SENSE

3 - DRL/NTC-

4 - Bin SENSE

5 - NTC SENSE

6 - DRL LED CATHODE (-)

 

Thanks

If your willing to entertain a guess, pins 1(+) & 6(-).

That will supply power but it may not turn them on.   I'm not sure that's something you can bench test.  The control signals may be digital.

Thanks for the follow-up. I did bench test between pins 1 & 6 and the DRL would not light until I increased the voltage to 16 volts. If they are digital as you mentioned, then I guess these fixtures can not be connected to the battery via a control relay. I wanted to add DRL to my 2017 MKX Premier which has the cutouts in the bumper but does not contain the required wiring assembly. It appears that I have to abort the project.

Thanks again.for your comments...

Yeah, you would have to Buck Boost it to 16-18V off of your 12V relay source.

 

(Example of an adjustable Buck Booster...)

Thanks for this insight. I did not realize that theses buck boost were available. I don't think that I would want to add another device  to my MKX. Would you know why these factory DRLs require a higher voltage?? Was thinking abut replacing the internal LEDs in the factory DRL with a standard 12 volt after market but that would be a extreme measure. Whatever I do, it needs to be reliable b/c I have to pay the body shop to drop the front bumper to install a pair of factory DRLs.

 

Thanks, Ron

I'm more inclined to think that akirby''s remarks may be more on target. The lights only need 12 volts, but must be triggered by a gate circuit. (Simular to a SCR).

 

Before preceeding you need to get hold of a schematic.

 

Maybe a harness like this will work?
