Good afternoon, looking for help on a CXN 613 with a few codes. SID 277 FMI 9 EGR gas mass flow sensor, perform service as soon as possible, abnormal update rat. SID 27 FMI 4 Actuator for VGT, current too low or short circuit caused by malfunction, PID 412 FMI 9 Recirculated engine exhaust gas temp, abnormal update time, SID 236 FMI 4 Supply relay, current too low or short circuit caused by undervoltage.
I'm not sure where to start but I think I'll begin with the low voltage codes. The truck lost power when these codes were active, they are now inactive and power is restored. Any thoughts?
