SPN 520235 — factory code KAMAZ and SITRAK

Safe to driveDrivable, but watch it yourself

SPN 520235 is a manufacturer number outside the standard J1939 table: different makes can put different things under it. Below — how it is worded by KAMAZ and SITRAK, and what the second half of the code (FMI) means.

KAMAZ

FMI 312V sensor supply voltage
FMI 412V sensor supply voltage

SITRAK

FMI 11ECU monitoring module: sensor supply voltage above the upper limit. Scan tool code: P1600. Effect: OBD limits torque immediately.
FMI 20ECU monitoring module: sensor supply voltage below the lower limit. Scan tool code: P1601. Effect: OBD limits torque immediately.

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.
