2000 Ford Focus SE

Discussion Starter · #1 ·
I have a 2000 Ford Focus SE. I'm currently trying to pass emissions, but the check engine light just came on. I attempted to read codes at autozone, but the OBDII device wouldn't power on. I bought my own tester to try and debug myself, but haven't had any luck getting it to power on. Some things I've tried:
  • Make sure plug is pushed in all the way
  • Clean the contacts on both ends with isopropyl alcohol
  • Checked all fuses under the steering wheel
  • Confirmed cigarette lighter has 12V
  • Confirmed battery voltage is within acceptable range
Any help would be greatly appreciated.
