Does anyone know how to get the next subcode after P0AA6 526 on tech stream? I've tried clearing it and then driving to wait until it codes again but after like a 300 mile drive it doesn't even code again. But then if I shut off the car, it codes again P0AA6 526 upon startup. If I don't clear the code on startup, then after I shut it off, it wont go into ready mode anymore. During the 300 mile drive, I'll have AC on and all that and it still wont give codes. Any help is appreciated. Thanks.
