msarbora Posted October 22, 2018 Share Posted October 22, 2018 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?

turckster Posted October 24, 2018 Share Posted October 24, 2018 All of these faults are voltage related. Fuse 38 powers the EECU, make sure it has battery voltage (12+ volts). Fuse 38 gets its power from the starter relay. Make sure all battery, starter and ground connections are clean. Checked the ground relay connections on the firewall as well.
