Question
Axiom2000
I have a 2005 Surburban and recently on occasion it would act as if it were operating on low power. Today while driving it acted that way and I got a check engine light, a friend of mine read the code and it was P2771, 4 Wheel Drive Low Switch Malfunction. I also noticed it switched to 4WD on its own and I could not get it into 2 WD. At any rate we reset the code and it is fine now however I believe it will come back again. What is a Low Switch Malfunction and what is it going to take to fix it.
Oh I also seem to be having a problems with the speedometer, it has a mind of its own sometimes it works and sometimes it takes a vacation. I understand this is a well known issue with these vehicles?
