The older Isuzu’s you could do this, that is how I pull the codes from our 92 Amigo but as far as I know you need a scanner for your VX. .Originally Posted by I_Wanna_Retire
PEP boys or Autozone will have a scanner for less than $100 that will give you the codes and a book to tell you what they are. I use mine all the time to clear the damn fuel purge system code that seems to be an issue every couple of months.
