    Did anyone ever figure out how to disable the drl?

    Does the cts fix for clipping the wire work? Can a tech 2 scan tool actually do this? I just replaced my first bulb, and out of principle, I never want to do that again.

    I have searched and searched with no concrete answer.

    I've never heard of this option, but I sure hope it's possible. In 4 years I think I've changed a bulb 5 or 6 times, and it's a royal pain in the @ss. I'm not sure which is a worse design, the difficulty of changing it, or the fact that the front turn signal is disabled when the bulb fails.

    It's frustrating how a little nuisance like this colors your whole view of the vehicle.

    Why on earth would you disable a safety feature like DRL? DRL has been proven to reduce accident rates.

    My DRL (city lights) stay on with the main lights. Main lights are used as DRL in Europe, they have to be on during day, but that city light is a waste having it on with the main lights, unless you change it to a bright LED in its place. IMO city lights should go off when main lights go on.

    I have to 100% agree with 08SRX (make a note on this one)

    I have changed 2 turn signal bulbs in like 7 years on two SRX's, it takes 1/2 hour so not a big deal really.

    Meanwhile Europe has dedicated DRL as well. They shall run without tail lights on.
    I understood the square DRLs are disabled in the Europe spec by programming (lightpipe only) as amber DRL lights are not allowed in Europe. I would've liked to replace them by LED-bulbs though and enable them. But I never got to get the gen II CTS...

    Not sure I understand what your saying,square DRL, do you mean the fog lights,euro DRL is the low beam on during the day,I believe Germany has not made it a law yet for lights on? Or as the modern cars have now like Audi led strips

    Sorry to answer so late.
    The Gen II CTS has light pipe in the front and amber DRL. And the Amber light in the head light unit is rectangular. Right?
    In Europe the rectangular (amber) light unit inside the head light unit is disabled, because amber DRL is not allowed in Europe. DRL is only allowed when white and not too bright and without tail lights on. Yes, Audi has those white LED-stripes, but many brands now have some sort of LED DRL in the current models.

    Had many arguments with yearly inspection here in the uk regarding lights in the past. Sequential rear on cougar. Amber front on firebird.my 2009 srx has no drl but I'm guessing they share the front turn signal unit. Yet land rover discovery has amber city lights over here as does 5 series bmw. We also get clear smoked rear lights on srx. As mine is crystal red your lights would blend in much nicer. Jobs for the summer i think.

    Re: Did anyone ever figure out how to disable the drl?

    I'm wondering if anyone has figured out how to kill the DRLs too. I have an '06 SRX I just picked up and want to kill them. I tried the same trick I used to kill them when I had my '04 CTS, but the SRX has more pins in the little black box than the CTS does.

    Only option I know of is to use the tech 2 to reprogram the IPM to an export country like Germany for example that doesn't call for DRLs. You can also enable the option to have fog lamps remain lit during high beam activation.

    Bah. That's about what I was afraid of. I have hookups at GM dealers and other shops so it's not a HUGE issue for me, I was just trying to avoid having to call in favors.

    Re: Did anyone ever figure out how to disable the drl?

    I've been looking at this for different reasons.....
    There appear to be different flashers for Domestic and Export versions.
    the non-common pinouts from the flasher look like this:
    Pin Wire Color Circuit No. Function
    A D-BU 5364 Left DRL/Turn Supply Voltage (Domestic)
    A L-BU/WH 1314 Left Front Turn Signal Lamp Supply Voltage/Left Turn Signal Indicator Lamp Supply Voltage (Export)
    H D-GN 5365 Right DRL/Turn Supply Voltage (Domestic)
    H D-BU/WH 1315 Right Front Turn Signal Lamp Supply Voltage/Right Turn Signal Indicator Lamp Supply Voltage (Export)
    hey this was a great looking table in excel my apologies for the formatting.

    if you are adverse to going to the dealer you may want to look for an export flasher and see what it does. it does not state DRL in the export pinout functions.
    regards,
    Mac

    This is because the DRL is handled by the IPM (computer controlled).

    The flasher is likely different for export as they probably have the repeater lamp on the front fenders. However I really doubt the actual flasher is different and it comes down to wiring.

    If you're ever in MN I have a tech 2 and would likely be willing to change these settings on a forum member car.

    I got tired of replacing the DRL bulbs and put in LED replacements (array of LEDs) that plug directly into the same socket. It's a bit of hassle wiring in the ballast resistor (so there is no rapid flashing), but it's been 4 years now without a failure.
