Do not driveTo the nearest safe stop
SPN 35 is a manufacturer number outside the standard J1939 table: different makes can put different things under it. Below — how it is worded by Ford Trucks and ZF AS-Tronic, and what the second half of the code (FMI) means.
Ford Trucks/Ecotorq writes fault numbers in its own format: the code in the table below is a Ford code (hexadecimal, zero-padded), not a J1939 SPN. It matches the standard only where the signal itself is standard, and usually matches the title of this page by digit alone.
| FMI 0 | Urea Tank Temperature Sensor Electrical – On / Off Power. FODP code (scan tool): P2045-00. |
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 10 | Fault on valve Y3 output circuit (front splitter group). With a direct-drive (DD) gearbox, shifting into the fast group is not possible. With an overdrive (OD) gearbox, shifting into the slow group is not possible. |
| SPN 35 FMI 035/0 · 35.0 | data above normal range (most severe level) |
| SPN 35 FMI 1035/10 · 35.10 | abnormal rate of change |
Do not drive. Stop as soon as it’s safe to do so — don’t keep going.
The code is flagged critical: the manufacturer considers it unsafe to keep driving without checking.
This code alone cannot say what will fail next, so stop at the first safe opportunity and look at it on the spot.
That said, the manufacturer flags this code as critical — if in doubt, it is safer to stop and check on the spot.
