I just purchased a Kobra code reader and need to clear a p420 code. There is a warning that freeze frame data and manu specific enhanced data will also be cleared. Also IM readiness monitor status for all vehicle monitors is reset to not ready or not complete status.
Mechanics have cleared the codes on this vehicle several times. I was wondering if all code readers carry a similar warning or if mine is different and I need to look for a reader that will erase just the diagnostic trouble codes, or do they all erase all the codes?
Just want to be careful. Thanks for help!
