Unable to clear some fail codes ecm. - samuel77 - 09-23-2025
Hi are there another more aggressive way in orbit to clear fail codes in the ecm.
They are old but seem to got stuck in the memory.
Any suggestions ?

It depends on the DTC codes you have.
Some DTCs require additional procedures such as resetting fuel trims. Otherwise they will come back.
You can also try clearing the DTCs from Orbit and then disconnect the battery for a long period of time. In some cases, stored DTCs are deleted with this.
But before all that enable the details and see when was the last time they are reported. You might still have issues.

Thanks for the reply!
