i no the check engine light is always on now even when the cluster is acting normal i took it into a dealership they said it was just a lose battery cable then a repair shop said its seems to be a bad computer module and now im back at another dealership thats all i know they havent told me of any codes or anything i just know what its doing and what they think it is

my car just started doing this 2 days ago while im driving or the car is running theres a service advanced trac and tire pressure sensor failure showing up aswell as my needles flying up and down as it bings with all the lights on as if the key was just on and not running dealership that i took it in said it was a lose pos battery wire connection causing it so i tightened all the battery connections and it still is doing it any help would be great
