Thanks for the update (I was wondering). BTW, nobody yet, as far as I can tell, has "ever" reported that replacing the brake pressure sensor has solved the trifecta, despite many people (including me) reporting the code for it.

Good for you. In general, either the larger steel wire lifts off its gold bondpad (you check with a magnetized needle) or the angle-hair-thin gold wires flop about due to some sort of defect with the snot-like goop that's supposed to prevent that from happening.

We'd LOVE to see a picture of it!

I think the only "repair" so far has been to separate them from touching and applying new goop to prevent them from flopping about.

Funny you should ask.

I think it's clear by some accounts that you "must" code the VIN; yet, by other accounts, it's not so clear what actually happens if you don't bother.

Here is the thread for you to add your experience to:
