Is there an affordable scan tool out there that will scan BCM codes. I'm having a service park assist issue on my 15.5HighCountry LML and none of my scanners will come up with a code for my issue. I have the torque pro app. An autocal for my LBZ and an Ancel scanner that does the auto brake bleed and stuff. But none of them will help with my current issue. What is a decent and possibly kind of affordable scan tool that might help me out?
