The term "accident reset switch" is not a real automotive term. Cars don't have switches that magically erase the memory of an accident.
Here's what you should know:
* Airbag systems: The airbag system in a car is designed to deploy only once in an accident. If the airbags have deployed, the system needs to be inspected and possibly replaced by a qualified mechanic. There is no way to "reset" them yourself.
* Diagnostic trouble codes (DTCs): If your Jetta was involved in an accident, there might be diagnostic trouble codes stored in the car's computer. These codes can be read by a mechanic using a scan tool. The codes might indicate damage to the airbag system or other parts of the car.
* Repairs: Any damage from an accident needs to be professionally repaired. A mechanic will assess the damage and make the necessary repairs.
It's important to never tamper with your car's safety systems. Doing so could put you and others at risk. If you have questions about your car's safety systems or need repairs, please contact a qualified mechanic.
