Expert:  Ronnie replied 2 months ago.

The code that sticks out for the problem you are having is the 2797 code which indicates the Driver coolant control valve open circuit . Are you able to test the system if I send the steps?

Okay I have enclosed the complete systems diagnoses file. Your going to want to scroll down to pinpoint test J1 for this code. Have a look and see if this will help you determine the cause.
