LED conversion issues

So I bought the LED headlight conversion from xenon depot. Supposed to be plug and play. After I turn my headlights on, after a few seconds to several minutes they turn off. Why is this happening? I do not have the CANBus, because if I was reading it correctly you only need that if the headlights act as DRL's, which they don't in the Sierra. Was I mistaken and should order the CANBus?

You'll need the CANBus ones or add some error cancellers

Dammit I was afraid of that. On their writeup for the 2016 it specifically says you'll need the CANBus but didn't say anything about it for the 2015 so I figured I didn't.

The Truck's 'computer' sends a low frequency 'signal' to the headlight to make sure the bulb is still on. If it sends the signal to your bulb and doesn't detect the correct halogen voltage draw, the 'computer' kills power to the light. (I say 'computer' because I'm unsure what that system is called) I only have issues during the day with my DRL's on my 2015 Chevy Silverado LTZ. You sure it won't work at night, or when you turn the switch to 'on' as opposed to 'auto'? I've been running mine for a year or so without error eliminators (aka for this discussion- canbus) on my LTZ. I'm about to go back in and swap out the hi beams. At that time I'll connect the error eliminators to the lows as well as the highs. PS, I recently had a bulb go out and upgraded to the newest version Xenon Depots. When I first connected it, it powered right up then went out. After I messed with the headlight switch, turning lights on and off, the bulb fired up and now I have no issues at night.

This happened to me today with my new led headlights 15 GMC Sierra LTZ. I guess I need error cancellers. They work no problem until vehicle is started.

Yeah you'll need them, I learn this while doing the '16 front end swap on my truck I could turn them on with no problem while truck was off but they would turned off once I started the truck and so I tested the current and it was pulsating while truck was running so I just added the error cancellers and the pulsating stopped.

Ordered my cancellors today and also let Xenon Depot know that although their write up for the 2016 Sierra specifically says they are needed there's no mention of them in the 2015 or 2014 write ups. They said they'll edit their write ups to help future customers from making the same error.

      2015 Sierra Denali L86 cyl 5 misfire at idle

      By Gkistler · Posted

      Hi friends - first time poster. I have a 2015 sierra Denali with 150k miles, I’m the second owner and she’s given me 75k of great service. I run a pulse AFM disable device. Starting Thursday when I exited the freeway after a short local ride it started idling rough, with an obvious misfire shake and was down on low end power.  I got it home and hooked it up to my scannner and found no codes but in live data a pretty bad misfire on cylinder 5. I replaced the coil, plug and wire with all new OE replacements (Delphi gn10165 coil, acdelco wire and 41-168 plug). It’s still behaving the same way after firing the parts cannon at it.   I know cyl 5 is a non AFM cylinder so I am not thinking this is AFM related but I’m kinda at a loss. injector? Bent pushrod? It’s running too well over 1k rpm to suggest those IMO. Has anyone chase this issue before and what was it? Any suggestions?

      Pulsating Noise 4Cyl Mode

      By zibzer2 · Posted

      2017 Silverado L83 5.3l 6speed transmission Hello, not a new member but havent posted in a while and my old signup info isnt working so had to create a new account. anyways, I have an issue with my truck and hope someone can spread some light on whats happening: -when it goes to 4cyl mode it makes a clunk sound (but not when coasting or going downhill) -when in 4 cyl mode and under load it makes a load pulsating sound (not a tick). -goes away completely when in M5 gear or when plugging in an AFM delete. Im guessing it is one of 2 things but im not convinced of either to be honest. 1. lifter stuck in v8 mode 2. torque converter shudder realistically it doesn't seem like the TC as there is no physical vibration , and it never happens in v8 mode. but maybe? and wouldnt a lifter make a sound whether with load or not? any ideas let me know please. thank you!

      Some Assembly is Required

      By Chuck FB · Posted

      Which has made me wonder with the various engine failures of a few brands in the last few years, is it sub par materials such as lifters etc causing failures, or bearing clearances on the crank etc or perhaps bad designing of an engine physically or causing too much load on the components due to the hp/torque they can push out of them. Or is the oil viscosity and additive package of current oils or a lack of oil flow by an oil pump not able to supply sufficient oil at idle or under high load at low rpm. Or is it every item I listed that combined together has pushed the limits so far to the left that there is hardly a margin of safety left and add in some fuel dilution and too long of an OCI and premature engine failure is the result ?.

      He is not saying that an SAE *W20 will have more viscosity than a *W40 due to MORE VII polymers. He is saying that although multiple *W40 may post in the PDS the same or similar 100 C and 150 C viscosities that the blenders choice of modifier TYPE and AMOUNT to get his chosen base to grade will not give identical real world viscosities in shear and at temperature. All will pass the SII test but not all will pass the 100 C HTHS (unpublished value) testing the blender does and relies on to get the required by law "percentage improvement' referenced to his last great work.    Tis the problem with the lie. Once told others are required to support it.

      Parking Brake - Automatic Engagement Questions

      By PunchT37 · Posted

      I have a `25, 1500 that auto sets on incline. Never knew that at first. I have the electronic shifter. Just think if it didn`t do that? Unlike a mechanical shift that you can muscle out of park, how would you get this thing out? That would be a problem.   What I found out later is, I don`t have to push the button to release. Just put it in gear.   Setting parameters? Don`t know if it`s possible.
