Hey new to this forum. I'm having the same issue. I own a 2016 Silverado. I did however swap all rear bulbs to LED. Hyperflash started right away but rear vision service happens about a week later. I went the online resistor route to no avail. So I bought new gm taillight wiring and replaced the now spliced mess back to stock and reinstalled the factory bulbs. Hyperflash is obviously now fixed but I still have the service rear vision system message. When going into reverse the wheel grid pops up then goes away to the message. I dont see any reset buttons and I have checked every damn fuse. Really dont want to spend thousands to replace the system. Hoping anyone can help me thru this mess.
