Thanks for the info, very interested in this mod now, but will have to wait until after my Hawaii trip ::.

In the mean time, would care to explain where and what controls the '06-'10 drl system? I don't want to wire the '11 leds to be on using the stalk in the parking light or on position. My idea is to use relays so the leds come on when the ebrake is disengaded with the car in the "ON" position (like how stock does). If I can understand the drl system better and how it ties in with the high beam, maybe I can simplify the mod. This bean network is ridiculous..

 

i can't really help with your question, but i'm kinda confused about this. you have the LED and a separate DRL?

 

^yes... He has 2 DRLs now... One from his high beams at low wattage, and one from the LEDs. He wants to disable his original high beam DRL.

 

Jeff's IS didn't come with the led headlights so his stock drl is the high beam bulb. He switched his stock headlights to the led ones and now have two drl's working at once. He is trying to turn off his stock drl but the option appears to have been removed.

 

im pretty sure you can turn them off, maybe its not called DRL.
it was also posted in one of the 2011 LED headlight thread about the procedure to turn them off from a techstream. i have the 2011 headlights as well and the dealership turned the DRL off without any issues.

good luck!

 

Yes, I've disabled them on older IS models before, but this was the first time I've tried to do it on a 2011+.

It could also be a Canadian thing, DRL's are required by law up here, and I see the part number for the body ECU is different for Canada-spec.

Hmm..

Jeff

 

Jeff i have an 11' with the halogens and i had the dealer disable the DRLs when i picked up the car so it probably is a Canada requirement !

 

Whoa I want some in on this...more info on this please, if its one of those things you can't post up due to CL rules some PM me with this info. I got the 06-08 halogens and they suck!!! I would love to have the 2011's and get a retrofit on those

 

Yeah that's looking more and more like the case.

Well then....

Jeff

 

I hope those assumptions are wrong for your sake Jeff, in my 07 I was infact able to disable the DRL but I did it before installing the 2012 headlights.. please post a picture of how it looks like with both DRL and LED..

 

Jeff

 

I think the best way to fix the issue is to get a front controller ECU from a car with LED DRL, but it's going to cost me.

In any case, I'm not really in a rush to fix it, I am going to work on another way to disable DRL. It's quite clear to me now that it cannot be disabled via software.

Jeff, are you gonna use your diagram and try to enable LED's like it's on '11 models?

 

I did, it worked as expected.

Please tell me you took some pictures and you're gonna post a diy
