Safe to driveDrivable, but watch it yourself
SPN 520195 is a manufacturer number outside the standard J1939 table: different makes can put different things under it. Below — how it is worded by KAMAZ, MAZ, SITRAK, Volvo and YaMZ, and what the second half of the code (FMI) means.
| FMI 15 | EGR valve: positive deviation |
| FMI 15 | EGR system control error - Positive deviation above normal. Blink code: 6-1-1. Repair: Check the EGR actuators and sensors and their wiring. |
| FMI 2 | Implausible temperature sensor reading at cold start, combination 0. Scan tool code: P1000. Effect: Fan and warm-up control may misbehave. |
| FMI 8 | Error of the first fresh air temperature sensor at cold start. Scan tool code: P1000. Effect: Fan and warm-up control may misbehave. |
| FMI 5 | LCM output current to the lamp is below 0.1 A. Open supply wire between the LCM and the lamp, open wire between the lamp and the ground point, or lamp failure. |
| FMI 6 | LCM output current to the lamp is above 3.1 A. Wire shorted to ground between the LCM and the lamp. Possibly several lamps are connected, or a higher-wattage lamp is installed. |
| FMI 15 | EGR system control fault (Positive deviation above normal). Blink code: 6-1-1. Repair: Check the EGR actuators and sensors and their wiring. |
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.
