Service Brake circuit #1
I got a fault code spn 1087 fmi 1, I googled and apparently it's a service brake circuit #1 problem. I connected insite but it wouldn't show me the fault, I could only see the fault on my dash. Does anyone know where this circuit is located? I'm thinking its somewhere in the dash but I'm not sure.

Insite is for engine. If you have brake faults you can use Inline adapter and truck or brake manufacturer program to run diagnostic.
If break are Bendix made http://www.bendix.com/en/servicessupport...acom65.jsp here is free diagnistic software.
Cummins FAULT VIEWER could help too https://www.cummins.com/parts-and-servic...ult-viewer
