Hey there, thanks for the question.

are you saying that if you turn the key to ON position the condensor fan at the radiator is coming on? even though the engine is not running?

ok, that's a fail-safe condition. That means there is a major control unit failure. Not a good sign

Expert:  Jake replied 1 month ago.

I would double check your fuses to make absolutely sure there is not a fuse that powers the ECM thats blown or something like that.

otherwise then you likely have a major control unit failure and need to perform CAN diagnostics to see which one.

I have a obd 2 scanner will that work?
Expert:  Jake replied 1 month ago.

the OBD scanner likely won't help here, but you could check for codes IF it will even communicate at this point.
