just a generic guess .. as I do not know what engine or vehicle this is .. but so far ...
spn 102 fmi 18 = cummins fault code 125?.
FC 125 = something wrong with the intake manifold pressure sensor (or whats known as the imap sensor on a newer engine) and its indicating that boost pressure is lower than expected.
Fault code 125 is basically a generic "Low Boost" alarm.
That Could be a whole lot of things that can cause this, either in the intake, the turbo itself, maybe in the exhaust, or even in the EGR system.
