Safe to driveDrivable, but watch it yourself
SPN 520196 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, Volvo and YaMZ, and what the second half of the code (FMI) means.
| FMI 17 | EGR valve: negative deviation |
| FMI 17 | EGR system control error - Negative deviation above normal. Blink code: 6-1-1. Repair: Check the EGR actuators and sensors and their wiring. |
| 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 17 | EGR system control fault (Negative 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.
