Actually the OVP is quite a device, so simple, so efficient and absolutely a piece of cake to diagnose.

It's simple efficiency assures the worlds two most durable computers the long life they are noted for. I have replaced more GM computers (and I don't work on GM cars) than I have KE controllers and ABS controllers combined.

And if it weren't for OVPs, those who haven't a clue would have to start throwing expensive parts at it right away. Think how much money is saved by throwing an OVP at it first rather than a KE controller.
