I have a 2013 Advance - ACC and CMBS Light came on. The ACC light went back off and cruise control still works including the adaptive part. I thought per other posts that it was the battery - AZ tested it as bad, replaced it, light is still on. The sensor obviously works since it detects cars, just the collision part is not working. Cleaned the plastic grill, tires are fine and match - where to from here. Any thoughts? Brake and cruise control switch on the brake pedal? Any ideas would help - hate taking it to the dealer cause our local one charges crazy prices.
