cement head Posted January 3, 2019 Share Posted January 3, 2019 Hey folks, I have a 2015 Mack that is showing the engine shut down light. im getting codes SPN: 4813 FMI 5 AND 4812 FMI4. Both oil system related. Its also throwing 647 fmi 5 for clutch fan. Im thinking wiring. I have cleaned the connections at these actuators and don't see any clear signs of bad wires. Any pointers.

Mackpro Posted January 3, 2019 Share Posted January 3, 2019 If MP7, the oil thermostat actuator on the oil filter stand is probably bad and possibly shorting out other sensors. We change a lot of them. Quote Link to comment Share on other sites More sharing options...
