What is the wrench light on my Smart Car, and what does it indicate?
The wrench light on your Smart Car is a dashboard warning light that illuminates when the vehicle’s onboard computer, also known as the Engine Control Unit (ECU), detects a problem with the engine or transmission. This light is usually yellow or orange in color and is shaped like a wrench. When the wrench light comes on, it means that the ECU has detected a fault code, which is a specific error message that indicates the source of the problem.
The wrench light can indicate a wide range of issues, from minor problems such as a loose gas cap to more serious issues like engine or transmission failure. In some cases, the light may come on and then go off on its own, while in other cases, it may remain illuminated until the problem is diagnosed and repaired. If you notice the wrench light on your Smart Car, it’s essential to have it checked by a qualified mechanic as soon as possible to avoid any potential damage to your vehicle.
