Omega General Help / Re: ODBII only read codes with engine running
« on: Today at 17:33:00 »Ign on should be enough.
Are you getting power on the ODBII port with ign off? Should have perm 12v supply to it.
Yes it gets power when everything is off, but the reader needs ignition on to connect and link to the car.
Everything looks OK with IGN on until I want to read codes or erase codes then it says it can't link to vehicle.
Same problem had the guy at the inspection.
Just before the inspection I got connected with engine running to see if there was any codes that could cause a notification at the inspection. And it works as expected then.
I'll check on my other 2.6 Omega and see how it behaves.
