Any idea what SPN 3216 FMI 20 means?
I've got the 450 hp ISL engine (2104 Allegro Bus 37AP) with an MIL light on, SPN 3216 FMI 20 code. I've searched for a cross reference on the Cummins codes, but none show that complete code.
I think it is the same code that has periodically appeared, then cleared by itself. I'm just trying to get ahead of the issue if this code is going to continue to come up periodically.
