SPN 611 — System Diagnostic Code #1

Safe to driveDrivable, but watch it yourself

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 3Injector 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 4Injector driver capacitor — short to ground. Repair: Replace the EECU.
FMI 6Injector 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 14Axle 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).

Can I keep driving

Safe to drive. Below — how much time you have and what happens if you keep going.

What happens if you keep driving

Time you have: Drivable, but watch it yourself

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.
