Hi everyone, I'm new to the forum and have been a mopar man since I was a kid. I live mopar, but right now I have no car... Cause my 08 charger 3.5l has a serious abs issue or trans issue and I am hoping for abs. But it is engaging the rear breaks when driving a 60+ mph.
I am not sure if its a wiring issue that's causing it to engage, but its way unsafe. Now I am mechanically inclined and have fought some gremlins before but this has me lost.
So my question is...

What would cause the abs to engage with out using the breaks?

After the breaks engage the car goes into limp mode. Some times it wont even start after it does it.

The only code the dealer has found that pertains to the abs is a loss of communication to abs unit. What do I do cause the gas can is looking really nice atm.

Thank you
