What is a epsm?? I'm having the same issues but I don't know what the heck you are saying lol.

Ok electric power steering module. so if a module was fried would it do the same thing? Would this need to be programmed if I had to change the electric power steering module??

I'm not going to read this thread. Explain your issue or start a new thread.

Moved newer posts from an unrelated 23 month old thread to this new thread.

Please start new threads for new issues, this eliminates a lot of confusion. Please refer to https://www.gmforum.com/introduction...-first-304557/ for more details.

Okay, done sorting. To clarify further:

The previous thread listed the following issues:

​​​​​​​​​​​​​​​​​​​​​
Which one is your car having?

​​​​​​​2013 Chevy Equinox 2.4.. seems as if moving my comment which went right along with the other guys thread about the epsm went perfectly in line! I call my buddy at a dealership asking what a epsm was and he said he didn't have a clue. My gas gauge isn't functioning, my temp gauge isn't functioning, no communication to any module, no crank no start, have power to everything else ect.

Why not put his complaint in a brand new thread. This is still very convoluted.

Ok. What kind of scan tool are you using. What is the network impedance with all hooked up? Is the ignition switch working?

Ah okay now we're getting somewhere.

You have a no ECM and no BCM issue. The other thread was about an Equinox with a bad engine. The EPSM is a symptom but likely not directly related to the problem.

​​​​​​​I'd start by disconnecting modules until you get communication, then reconnect one at a time until you lose communication. Whatever you reconnected last is probably a problem module.

I did, his complaint was:

He said he'* having the same issue . . . but didn't specify which of the sixteen issues in that thread he is having. Now that he has responded it sounds like he has issues 3, 4, and 5 from my list.
