BCM reflash for LEDs

[SailorX]

Is there anyone out there who knows how to reflash the BCM to use LEDS in a 2015 Silverado? I hate the resistors!!!

 

thanks

Whites automotive $350 I think. 

 

I tried like 3 different dealers, only 1 said they would and then in the end they said they couldn’t. 

 

He said they have on 2500’s and up, but won’t on 1500’s. 

 

I hate the resistor idea myself, but that’s what I ended up putting in.

What happens to the LEDs if you don’t use resistors or get the BCM flashed?

They flash really quickly compared with the regular flashing frequency.

They flash fast and throw code that the light is out.

What's wrong with resistors? ?

I’ve been using Phil’s resistor adapter for 7 months without issue if you’re concerned with reliability?

I have used resistors also and they last about a year also you have to splice the harness and they have to be mounted. I know it’s possible and easier just to have the computer programmed. So just trying to find a way.

Resistors are just a crummy way to do it in my opinion. But in the end, that’s what I’m using.

Good luck finding a way. 

 

Ive got a spare BCM and a buddy who likes hacking chips, we are planning on playing around one day with it. But from what he tells me, he would have to make a change and then put it in the truck and see what changed, which means testing everything. 

 

And then make another change and test it. 

Were talking hours and hours and hours of changing 1’s and 0’s and testing everything until you find the difference. And then repeat over and over. 

 

Probably why WAMs charges $350. Probably spent 5,000 hours testing every little thing the BCM controls

Okay. I wish you luck sir.

What are you using to hack the BCM? I might contact WAMS to see if they can program the BCM.

Oh I don’t know. My buddy is the one Into all that. Sounds like he just needs to get the data lines though

WAMS can definitely program the BCM.  You just have to have the brake pedal relearn procedure done afterwards.  $350 buys a lot of resistors.

But it doesn’t buy you all the other cool stuff we can do while we are in there such as extend remote start run time, fogs with high beams, extra flashes on flash to pass speed limiter removal etc etc etc ;)
