Stumped on this one. I have tried every variation in the tune to enable VSS output on this E38 and all I get is a constant 12v. C1-57. No matter what combo I do H0159 and H0162, all I get is constant 12v with key on. Any ideas? Never had this happen before.
This is the stock tune pull. Nothing modified.
