J1939 code SPN 611. Below — how the fault is worded at the factory by Bendix ABS/ESP, International and Renault Trucks, and what the second half of the code (FMI) means in the standard.

| FMI 14 | wheel speed sensor failure in previous power on cycle |
| FMI 3 | Virtual Fuse — Unexpected Connection |
| FMI 3 | Injector control voltage too high, or the injector driver capacitor shorted to battery positive. Repair: Replace the EECU. Check the wiring (J 1/10, J 1/11, J 1/12, J 1/22, J 1/23, J 1/24, J 1/41, J 1/42). If the wiring is in order, replace the EECU control unit. |
| FMI 4 | Injector driver capacitor — short to ground. Repair: Replace the EECU. |
| FMI 6 | Injector control voltage too low. Repair: Check the wiring (J 1/10, J 1/11, J 1/12, J 1/22, J 1/23, J 1/24, J 1/41, J 1/42). If the wiring is in order, replace the EECU control unit. |
| FMI 14 | Axle or wheel speed sensors swapped. Repair: Check that the speed sensors are connected correctly: front left (X2/4, X2/5), front right (X3/4, X3/5), rear left (X4/5, X4/6), rear right (X4/8, X4/9). |
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.
