SPN 520206 — LCM output current to the lamps is below 0.1 A (Volvo)

Safe to driveDrivable, but watch it yourself

SPN 520206 is a manufacturer number outside the standard J1939 table: different makes can put different things under it. Below — how it is worded by Volvo, and what the second half of the code (FMI) means.

Volvo

FMI 5LCM output current to the lamps is below 0.1 A. Open supply wire between the LCM and the lamps, open wire between the lamps and the ground point, or lamp failure.
FMI 6LCM output current to the lamps is above 1.7 A. Wire shorted to ground between the LCM and the lamps. Possibly several additional lamps are connected, or higher-wattage lamps are installed.
FMI 12LCM output current to the lamps is below 1.2 A. Open wires between the LCM and the lamps, open wire between the lamp and the ground point, or lamp failure.

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.
