i’m trying to get a read of my ecu with kess v2 after mpps gave me a “general reject” error and it still won’t read it just gives me an error before the reading even starts. i know i’m a noob and probably just doing something wrong but i’ve been seeing someone could have locked the reading through the obd2 port because it’s already tuned but i seriously doubt it is. also seen something about cutting a blue wire on my aftermarket radio to make it work which doesn’t make sense to me because i can read codes with my pocket scanner still. any help?
