    VCM Editor: Engine Diagnostics DTCs greyed out

    I have recently updated to version 5.0.4 and I have noticed that now some DTCs under Engine Diagnostics are greyed out and cannot be edited anymore.

    Is this a known issue? With versions prior to 5.0.4, I didn't have this issue.

    Yes. You will have to take the epa test to get the code to unlock the greyed out areas.

    Ok thanks. I wasn't aware of this new procedure.
