Cat ECM Password - Golfnut - 11-13-2019

I was going to use the Cat ET to change the engine brake settings on my Freightliner FLD with a C-12 and it asked me for a password. I had a dealership change this setting a few months ago so I doubt there is a custom password on it. Is there a generic password? If not how do I reset it?

On my truck, 1. 2, 3 gets me in, or 000, usually the norm...

you will most likely need a factory password.

it is 0000.
