check engine low voltage

[thcobb1]

So last week I got a check engine light on the port engine. everything seemed to run fine with the exception of the no wake assist would not work on the port side.

I took it in to a dealer to get the code and all that showed up was low voltage. However, I checked both the house and cranking battery. Both were showing fully charged.

What next?

BAD GROUND WIRE TO THE ENGINE is the usual culprit
