The Germans are a bit more advanced with their software capabilities. I used to have quite a few conversations via VW/Audi forums with Uwe Ross when he was designing the software. It is one of the bargains of the scan tool industry.

Canyon LED DRLs

I couldn't find another thread with this particular question. If I missed it, feel free to point me to it. Has anyone looked into making the LED lights on the Canyon come on and function as the DRLs like they do on the Sierra?

Were they able to reprogram them jot1teg?

Unfortunately not at this time. They have submitted the request to GM to see if there is a way to do this, but I am guessing not. I will check when I take it back for the next oil change. Really crappy GM advertised it as such for the 2015 models, but noticed the err of their ways when advertising the LED's as "signature lighting" for the 2016 models.

Would be nice if the fog lights illuminated with the LEDs for DRLs. Anyone rig this?

I recently bought a '16 Canyon, and the DRL's issue was one of my first complaints with the truck. I've been looking into this issue, and have found a possible work around, assuming people are still bugged by this? I still need to do some digging, and take some measurements of voltage output, as well as amperage draw, but I want to get an idea of what everyone wants before I dive in. What I'm wondering is this:

Is everyone wanting the DRL's to be just the LED accent lights, or would people still consider having the projectors on, while also having the LED accent lights on? It would basically be the same as night operation, but you could leave the light selector switch in auto all the time.

I don't mean to high jack this thread, I can always start a different one if needed, but I thought this would get out to more people based off subscriptions.

Thanks,
J.D.

I think most of us were looking to just have the LEDs serve as the DRL with no projectors on.

I would be into either, prefer the led's to be DRL but anything different would be nice. It look's so 2000's now. You can drive with the parking lights on but then you miss the auto-on lights. Talk about a fumble. They defiantly dropped the ball there. Especially since in the beginning they advertised LED DRL's running lights.

I would like the accent lights to be the drls instead of the low beam lights. Has anyone found out if there is a way to make the accent lights brighter?

I stared at the schematics in the sticky post and I think I have an idea that might work. If it does work, it should be relatively easy to implement in the form of a small harness that goes in-line with the connectors to the headlights.

First, some theory of operation for how each lamp is currently powered with the switch in the "Auto" position:
Day time - Low beams on ~60%, (low beams are PWM for DRL). Parking lamps off.
Night time - Low beams on 100%. Parking lamps on.

The LED signature strips are tied internally to the amber parking lamp within the headlight. Based on the logic above, the parking lamp signal can be used to swap the DRL signal to the parking lamp using a standard automotive relay.

The low beam power from the truck is diverted to the parking lamp/LED signature in the headlight through the normally closed relay contact leaving the low beams off during the day.
At night, the parking lamp signal is activated along with the low beams and this triggers the relay to switch the low beam power to the actual low beams.
The diode prevents the PWM DRL signal from reaching the relay coil and backfeeding the BCM but allows the parking lamps/LED signatures to function day or night.
The optional capacitor shown is used to boost the PWM DRL signal back to full brightness. This would be the same type of capacitor they sell for the HID relay kits to keep them from buzzing. Without it, the LED signature strips would be reduced brightness. I'm not sure how reduced but they're already pretty dim during the day so it's probably a good idea to add the capacitor.
There's another thread with a mod for the parking/turn signal bulbs that basically involves breaking off the terminals that go to the parking lamp filament so only the LED signatures come on. Combine this with that for a full package.

The headlight harness connectors are available from Mouser electronics, I bought all I needed along with relays and diodes off Amazon but haven't had a chance to build a harness yet. Total parts cost for a pair of harnesses was around $20 but I'm hoping someone with a little more knowledge of the truck's electrical system can verify my logic before I blow up my BCM...

Call James @ Supermodulation 732-690-6443

He knows alot about these trucks and he was working on a harness for exactly what your trying to do maybe you guys can exchange notes and make this happen!

Call Jarod at gen5diy.com they specialize in GM lighting they built me a custom harness to remove the daytime running light function he might be able to do something for you tell him Wes sent you he knows me he used my truck for R&D on the harness.

it was $139.99 the harness looked like it came from the factory everything plugged right in no cutting or splicing only connection I had to make was the power wire to the battery for the relays.

Did this just remove the DRL feature or did this work to get the LEDs to come on for DRLs. I have a HID kit and have been manually turning the auto feature off every time I'm in my truck.
