This does not need to be a complex switch, but all connections should be inspected. You seem to have isolated an issue with the park brake with a random -04 code. Fix that first. Being a new owner to a Gen1 Gem car you may not be aware there was a DC Converter upgrade/wiring update involved with your car. Depending on the status of the update on your car, it might be the next item to look at. If you have not discovered the archives yet, Use the search tool(magnifying glass) found in the upper right of this page and enter a few key words (such as Wiring Update). Here are two good examples of past conversations. > [@2002 Gem died, Bad Motor?](https://community.electricforum.com/t/2002-gem-died-bad-motor/24647/43): > > Hi Nato, I also have a 02 Gem 4 seater. Can you tell me how you went about the recall on the converter. I not sure the one I have has had the recall done to it. Thanks Richard > [@Why am I getting a -11 code on my 2002 GEM](https://community.electricforum.com/t/why-am-i-getting-a-11-code-on-my-2002-gem/26731/5): > > How would I know if i have the DC Converter Wiring Update? The -11 code now comes on even before I press the pedal. Turn the key everything is fine and as soon as I press the pedal the code turns on. --- _[View the full topic](https://community.electricforum.com/t/2002-e825-04-code-and-11-code/27000)._
