SPN 4010 is a manufacturer number outside the standard J1939 table: different makes can put different things under it. Below — how it is worded by International and Renault Trucks, and what the second half of the code (FMI) means.
| FMI 5 | Fuel Tank Transfer Pump — Fuel Transfer Pump Relay Under Current Or Open Circuit |
| FMI 6 | Fuel Tank Transfer Pump — Fuel Transfer Pump Relay Short To Ground |
| FMI 5 | Check the proportional solenoid valve, short to ground. Repair: Check the proportional solenoid valve (20-100 ohms), check the wiring between the unit and the component (3), check the control unit. |
| FMI 6 | Check the proportional solenoid valve, short circuit. Repair: Check the proportional solenoid valve (20-100 ohms), check the wiring between the unit and the component (3), check the control unit. |
| SPN 4010 FMI 54010/5 · 4010.5 | current below normal or open circuit |
| SPN 4010 FMI 64010/6 · 4010.6 | current above normal or grounded circuit |
Safe to drive. Below — how much time you have and what happens if you keep going.
This is an electrical fault: an open, a short or a bad contact in the sensor circuit. The value it measures is most likely fine.
You can drive. But until the circuit is repaired this system runs blind and cannot warn you about a real failure.
