If you get code 16 error on the information display of your Opel Corsa vehicle, there is a problem with at least one of the brake lights. Code 16 error indicates brake light failure, but you will get this error even if the brake light is intact but the bulb holder is faulty or if the power is interrupted due to low battery.
What is Opel Corsa code 16 error?
When there is a problem with any of the bulbs in your Opel Corsa vehicle, you will receive an InSP2 message on the instrument cluster display. If you also get code 16 error, the problem is the brake light bulb. If all of the brake lights are faulty, the engine will not start.
Code 16 error is a cheap and easy to solve problem. However, in some cases, vehicle owners can be confused. Namely:
For example, you received a code 16 error and you saw that the bulb does not light. You changed the bulb, it still does not light. You probably said that there is a problem with the bulb holder, you changed it as well, the bulb does not light up again. You have tampered with the cables, again no result.
Although rare, such things can happen. In this case, it is evaluated that there may be an electrical leakage in the vehicle or there may be a problem in the electricity coming from the battery. If the vehicle has problems such as electrical leakage, short circuit in the cables, the battery will discharge faster than normal and the battery life will be shortened.
You may also encounter a situation like this regarding the Code 16 error. You will get a Code 16 error, but you will see that the brake lights are working without any problems. So, in this case, should you continue by saying that there is no problem or should you tinker with the issue?
Even if the brake lights are intact when you receive a Code 16 error, you should investigate the cause of the code 16 error. This type of error is usually due to non-contact or sensor failure.
If there are short-term interruptions in the electricity coming from the brake light, the vehicle computer generates a direct error. However, even if there is a very short interruption in the electricity going to the bulb (about one tenth of a second), the bulb continues to burn because it continues to supply electricity.
Since the system perceives this as a problem, it generated the code 16 error. The problem here may be occasional inconsistencies or looseness of the bulb cables due to the bulb not being properly seated in the bulb holder. Or the electricity from the battery is weak from time to time.
The illumination of the brake light is controlled by the sensor. If the sensor itself is broken, it cannot detect that the brake light is on and the brain generates an error message.
