Hello everybody, Please excuse my bad English, I live in Senegal and my country speak only French.

I can't access any computer of the 2006 Cadillac Escalade ESV V8 6.0 (engine, transmission, chassis, body etc..) and the array of instrument does not work properly, I checked all the electrical circuit but there is no problem circuits or the fuses and relays have no problem too. What can cause this problem?
Thank you in advance!

Sorry to revive an old thread but check the fuse for the cigarette lighter under the hood. Might be helpful for others in the future.
