J1939 code SPN 96. Below — how the fault is worded at the factory by KAMAZ, Mercedes-Benz, SITRAK and ZF AS-Tronic, and what the second half of the code (FMI) means in the standard.
KAMAZMercedes-BenzSITRAKZF AS-Tronic
| FMI 4 | Fuel tank level sensor circuit shorted to ground |
| FMI 5 | Fuel tank level sensor circuit open |
| FMI 7 | Fuel tank level sensor signal out of range |
| FMI 9 | Fuel tank level. K-line code on KamAZ-5490: ADM3 17509. |
| FMI 19 | Fuel tank level. K-line code on KamAZ-5490: ADM3 17519. |
| FMI 13 | Fuel Level Sensor Missing or Not Available |
| FMI 19 | Fuel Level Sensor Received Network Data in Error |
| FMI 1 | Fuel tank level too low. Scan tool code: P0460. Effect: Power limited, the engine runs unevenly. |
| FMI 12 | Timeout of the DD CAN frame. Effect: Loss of communication with the modules, some functions are disabled. |
| FMI 19 | Incorrect data length of the DD CAN frame. Effect: Loss of communication with the modules, some functions are disabled. |
ZF AS-Tronic uses its own fault numbering: the number in the table below is an internal ZF code, not a J1939 SPN. It matches the title of this page by digit only and means something different.
| FMI 8 | No CAN bus signal: "cruise control set speed". |
Safe to drive. Below — how much time you have and what happens if you keep going.
Fuel is not arriving in the right amount or at the right pressure. It shows up first on climbs and under load.
You will most likely stall out on the road, and may not restart on the shoulder. A clogged filter or water in the tank you can nurse to a shop; a failing injection pump you cannot.
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.
That said, the manufacturer flags this code as critical — if in doubt, it is safer to stop and check on the spot.
Check the fuel filter and water trap, drain the water. In cold weather, suspect fuel waxing.
