SPN 520210 — factory code Foton, International, KAMAZ and others

Do not driveTo the nearest safe stop

SPN 520210 is a manufacturer number outside the standard J1939 table: different makes can put different things under it. Below — how it is worded by Foton, International, KAMAZ, MAZ, Meritor (ex-WABCO), SITRAK, Volvo, WABCO ABS/ESC and YaMZ, and what the second half of the code (FMI) means.

Foton

FMI 12Engine control unit fault. Effect: Diagnostic functions may be limited.

International

FMI 3HVAC Blower Output — Blower output circuit over voltage
FMI 4HVAC Blower Output — Blower output circuit under voltage
FMI 6HVAC Blower Output — Blower output short circuit

KAMAZ

FMI 255CAN: DashDspl timeout (instrument cluster)

MAZ

FMI 3CAN message DashDspl error - CAN bus message timeout. Blink code: 4-3-4. Repair: Check the CAN line connection to the other CAN devices.

Meritor (ex-WABCO)

FMI 10ESC Module CAN Messages/Blockdata Counter Failure
FMI 12ESC Module Failure Flag 'Internal Error'
FMI 13Failure Detection 'OverEquipped' for ESC module
FMI 14CAN Incompatibility of the ESC Module

SITRAK

FMI 2Number of injections limited by runtime. Scan tool code: P1011. Effect: Power limited, the engine runs unevenly.
FMI 20Number of injections limited by the high-pressure pump delivery balance. Scan tool code: P100F. Effect: Oil pressure lamp on, engine speed may be limited.
FMI 21Injection frequency limited by the system. Scan tool code: P1010. Effect: Power limited, the engine runs unevenly.
FMI 22Number of injections limited by runtime. Scan tool code: P1011. Effect: Power limited, the engine runs unevenly.

Volvo

FMI 5LCM output current to the lamp is below 500 mA. Open supply wire between the LCM and the lamp, open wire between the lamp and the ground point, or lamp failure.
FMI 6LCM output current to the lamp is above 5.2 A. Wire shorted to ground between the LCM and the lamp. Possibly several lamps are connected, or a higher-wattage lamp is installed.

WABCO ABS/ESC

FMI 1ESC Initialization Not Complete
FMI 2ESC System Configuration
FMI 5ESC CAN Datalink Fault
FMI 9ESC CAN messages missing, data erratic or incorrect
FMI 12ESC System Failure
FMI 13ESC Initialization required
FMI 14ESC Module Mounting Fault

YaMZ

FMI 3DashDspl CAN message fault (CAN bus message timeout). Blink code: 4-3-4. Repair: Check the CAN line connection to the other CAN devices.

Can I keep driving

Do not drive. Stop as soon as it’s safe to do so — don’t keep going.

What happens if you keep driving

Time you have: To the nearest safe stop

The code is flagged critical: the manufacturer considers it unsafe to keep driving without checking.

This code alone cannot say what will fail next, so stop at the first safe opportunity and look at it on the spot.

That said, the manufacturer flags this code as critical — if in doubt, it is safer to stop and check on the spot.
