Do not driveTo the nearest safe stop
SPN 264961 is a manufacturer number outside the standard J1939 table: different makes can put different things under it. Below — how it is worded by Iveco, and what the second half of the code (FMI) means.
| FMI 1 | Left front wheel sensor fault (air gap out of range) |
| FMI 2 | Left front wheel sensor fault (incorrect tire or tone wheel) |
| FMI 3 | Left front wheel sensor fault (short circuit to battery) |
| FMI 4 | Left front wheel sensor fault (short circuit to ground) |
| FMI 5 | Left front wheel sensor fault (open circuit) |
| FMI 6 | Left front wheel sensor fault (short circuit) |
| FMI 7 | Left front wheel sensor fault (incorrect tone wheel) |
| FMI 8 | Left front wheel sensor fault (wheel slip) |
| FMI 9 | Left front wheel sensor fault (wiring mismatched) |
| FMI 10 | Left front wheel sensor fault (speed signal dropout) |
| FMI 11 | Left front wheel sensor fault (abnormal speed / chatter, not stored) |
| FMI 12 | Left front wheel sensor fault (frequency too high) |
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.
