When does the DTRL come on?

everytime?
in that case im in trouble...
the passenger side DTRL seemed very unstable (sometimes on, sometiems off).
Thought it was the LED problem so i ordered two sets of LED and swapped them.
now both sides are not coming in.
I don't think its the LED problem since they were new, even if they looked pretty shitty.
Could there be other problems?
Maybe in wires or connections?
 
DTRL only comes on when Headlight is on (Parking light also). Unless you did the DTRL mod, which makes the light come on when fx is turned on.

you need to do a little more troubleshooting. maybe a loose connection.

He has a Canadian model... I thought that was one of the major differences between US and CDN, the DTRL is a real DTRL that stays on, no?

All of you replying have USDM versions, his is different. Any Canuck care to chime in?
 
He may not have a Canadian version, may have imported. And if this is true, he may have had to modify the DTRL's to pass Canadian inspection. Need more answers from him first, too many what-ifs.

If the engine is running, they are on.
 
Thanks for the clarifications aboot all this misunderstanding, eh?

Jokes aside, if it's not the bulb, it's the wiring. If it's intermittent like you're talking about, it's not the fuse. A fuse is a go-no-go, meaning either it's blown or it's good.

Water can cause intermittent grounds, as can frayed wire. A loose connection cannot cause intermittent grounds, but it can cause intermittent opens, which would give the same result except in the case of a ground it can blow the fuse, but an open cannot blow a fuse.

The best way to sort these things out is physical/mechanical agitation of the wiring, if you can trace it out. If you find a point where you tug or wiggle on the wire and it starts going crazy, like flickering on and off or just staying on, then you've found the culprit.

The water one would be very hard to figure out if it's something as small as "moisture" and not full-blown water leaking in.

I've done a lot of electrical trouble-shooting and ran across intermittent problems like this all the time. What usually solves it is a multimeter set on resistance (for that, you do NOT turn the power on to what you're checking...) and measure the resistance of that line to ground while wiggling it. Then again that's only in the event of it being grounded to the car somewhere.

See if you can figure something out based on those couple of methods (oh and check the fuses first and foremost just in case).
 
Sorry i couldn't get back sooner, ive been busy.
My gf and i were in LD relationship and she (with her mom=)) visited me for last 10 days. dayummm it feels like ive been dreaming.

Anyways, getting back to the topic..
I now suspect the fuse since neither DTRL are on whatsoever.
I couldn't find the thread with fuse location, altho i remember therea are two behind the driverside dash, and one another near the battery.
Could anyone give the specific location of the fuse for DTRL.
Thanks!
 
Did you get this yet? I believe the fuse panel (cover) will tell you what it's for... they're slightly generic, but you should be able to figure out what goes to the DTRL...

If you're at all confused, why not just pull them all? Keep the car off and pull/replace one-by-one and check for blown fuses. It can't hurt, and what if you find 2 blown and all of a sudden the DTRL issue is gone and the mood-lighting/mood-scenting feature starts working for ya? :ever:
 

Question.. What is the DTRL's mod? What does it do?

This mod is so you can have the DTRL's on all the time instead of just when your headlights are on.

One thing needs to be said for this setup:

This enables the DTRL-Light only! not the function what is meant by DTRL.
with this setup the light is always on as soon as you turn your key. and it will always remain on as the relay is switched by the accessory port - not DTRL-Function.

The original Function says that the DTRL goes off as soon as one of the other lights is switched on or when the park brake is on. In this case the light will ALWAYS burn.
One Site effect that was not mentioned here: by closing the circuit of the accessory relay, you also ALWAYS have power on 2 of the power outlets.

So this setup works to have the lights always on - but is not a real DTRL mod
 
I thought the DTRL is always on even when the headlights are on? But didn't you just say they go off when other lights come on? Or is that post mod?
 
before I did this mod, DTRL will come on only when HL/parking light are on.

after DTRL mod, DTRL is always on, regardless of the HL switch (and off when car is off of course)

I like this mod.
 
I haven't had a chance to fix it yet.
Well, i didn't bother bc they dont look too ugly when both sides are out.
Im having a lot of tiny problems just like DTRL and windshield wiper.
I'll probably have a dealer to look at, or just pass it out to the buyer "as i"s with little bit of hookup.
I don't know, we'll see:rolleyes:

Just completed this mod this evening. Wasn't planning on doing it, but my wife was watching American Idol.


DTRLs come on as soon as the key in the "IGN/ACC" position - because that is the power relay you are tapping into. DTRLs come on and stay on until you pull turn the key to "OFF". Turning any other light or switch in the car won't turn off the DTRLs after this mod is complete (not even the DTRL/Parking light switch).

Besides the fuse and the wiring, you could have the relay checked as well. Also - I found these and they are SUCH a helpful fuse to have in your fusebox! No more looking for a blown fuse - it jumps out at ya. Smart fuse, it's called.

After picking up my '06 FX. I always thought the dtrl's worked strangely. They stand for day-time running lights right? Yet they only run at night time. Odd. What were those engineers thinking? Great to know there's a mod for this.

My previous car had drl's and I liked the look. I used "hyper yellow" bulbs and it really provided some contrast.
