2009 Toyota Prius Hatchback 116000 miles
I keep getting a red triangle which disable the car to to drive. I can reset it by disconnecting the battery for five minutes then reconnecting it and then I can drive the car again. I’ve been trying to diagnose the problem. Many people say it’s the brake system the cooling system, low oil and I’ve checked the oil but it’s good. I’ve checked the cooling system. It works properly. But how do I check the brake system? Is there any hints or tricks on how I can get? What’s actually wrong with the car without going to the dealership?
