code 2 means issue is with the Gold Line. Try restarting it. I have similar issues and a restart fixed it. Wish I had a line, haven't had on since we had a winter 3 years ago
Means I'm luck to have a car in the bay, wish they were lined up lol. I invest so much for such a slow location. It's not located in an ideal place so the ceiling is very low on how many cars I can ever have come through. Now that they opened 12 new express washes, got even worse.
