LML GPCM delete?

[M.A.M.]

2015. Can I just loop the high side and low side can bus wires? Does it need the injector data to run or will it just throw a code that can be turned off? I know it’s been done on the LMM, but wasn’t sure if the newer stuff is any different.

Why take the GPCM out of the com loop? I don't understand this.

No glow plugs anymore, just cleaning up the engine bay. Minimizing components and wiring.

 

[Ron Nielson]

Makes sense. Thanks. Sure, just loop around the GPCM. I would think that there may be a code. you'll know soon enough.

Yeah, going to have to turn off the codes and maybe zero out the glow plug/grid heater tables in the tune

Appreciate it

I've done it on a lmm. Loop the canbus wires back together. It will still throw a soft code and the glow plug light will stay on
