Bad Batteries and OBD Codes.
Check your battery first if your Escalade is pulling electrical related OBD codes.
I just purchased a used car for my son. As is my habit when purchasing a used car, I reviewed the Carfax and ran an OBD diagnostic. I noticed on the Carfax the battery had just been replaced. When I ran the OBD the car pulled a P1604 code (Stability malfunction) plus four more codes, all of which were electrical related. My OBD designated them as current/history; meaning these were either current issue codes or old stored codes (It is a cheap OBD that doesn't distinguish between stored and new codes.) In checking for possible causes, I found a bad battery can be why all these codes occur. When I cleared the codes and reran the diagnostic the codes went away.
After doing a bit more research I learned a battery that is even just a bit low in voltage (but will still start the car) can trigger codes.
