J1939 code SPN 3361. Below — how the fault is worded at the factory by Dongfeng and SITRAK, and what the second half of the code (FMI) means in the standard.
| FMI 2 | Incorrect urea pump internal temperature. Scan tool code: P2047. Effect: OBD limits torque immediately. |
| FMI 9 | Timeout of a message from the dosing module |
| FMI 12 | Internal malfunction of the SCR dosing module |
| FMI 2 | DEF dosing valve jammed. Scan tool code: P2047. Effect: OBD limits torque immediately. |
| FMI 3 | Open load or high-side short to battery on the DEF dosing valve. Scan tool code: P2049. Effect: OBD limits torque immediately. |
| FMI 4 | Open load or low-side short to ground on the DEF dosing valve. Scan tool code: P2048. |
| FMI 5 | Open load or high-side short to battery on the DEF dosing valve. Scan tool code: P2049. Effect: OBD limits torque immediately. |
| FMI 6 | Over-temperature in the DEF dosing valve circuit. Scan tool code: P3009. Effect: OBD limits torque immediately. |
| FMI 11 | DEF dosing valve nozzle clogged. Scan tool code: P2047. |
| FMI 15 | Open load or high-side short to battery on the DEF dosing valve. Scan tool code: P2049. Effect: OBD limits torque immediately. |
| FMI 17 | DEF dosing valve jammed. Scan tool code: P2047. |
| FMI 22 | Open load on the DEF dosing valve. Scan tool code: P2047. Effect: OBD limits torque immediately. |
| FMI 25 | DEF dosing valve short to battery. Scan tool code: P2047. Effect: OBD limits torque immediately. |
| FMI 27 | DEF dosing valve short to ground. Scan tool code: P2047. Effect: OBD limits torque immediately. |
Safe to drive. Below — how much time you have and what happens if you keep going.
Urea dosing is interrupted and the ECU is counting. First the lamp, then a torque cut, then a forced crawl speed — the stages come in by engine hours, not all at once.
The truck will not die mid-highway, but the window shrinks with every running hour. Plan the repair now, not when the power is gone: an emulator or "deleting AdBlue" does not remove the problem, the codes keep stacking.
Fill the AdBlue tank. If it’s already full, the problem is dosing or reductant quality — you need a scanner.
This code is often not the fault itself but a knock-on. If any of these is in the same readout, start with it:
Scanner threw several codes at once? Paste the whole list — we will show which one is the root cause and which ones simply followed.
