We have a Schwaben tool and am seeing 3 permanent DTC codes. I cannot figure out how to clear them. There are no stored or pending codes.

The codes popped up because I needed to replace a coil, which solved the misfire - and the engine runs perfectly. I just cannot get rid of the codes!

 

Try using ISTA if you have it. If it doesn’t clear then it’s still an active fault.

 

Its should clear them,. must be still an active fault.

 

It was an active fault that was actually the HPFP, again. We are on pump #3 @ 80K miles.
