  • Welcome to Motor Vehicle Maintenance & Repair! Try a different code reader. If that doesn't work (you still come up with the error), I'd consider there's an issue with the Engine Control Module (ECM). Don't just exchange to a different ECM ... prove it out first. You should be able to get comms. The reason your reader is able to power up is because there is a power pin in the OBDII port which comes from the battery. Dec 23 '20 at 23:51
  • Make sure to confirm you have over 12V at the battery, ecm input and obd2 port. Honda modules like to not come online for much under 11.5V. Just because your tool is powered does not mean you have enough voltage.
