VALTRA FAULT CODES

: Modern Valtra models with SmartTouch display active service codes directly on the main interface.

: A flashing red "Stop" symbol on the dashboard indicates a critical fault, such as low oil pressure or alternator failure, requiring an immediate stop .

| System | Error Code | Description | Likely Cause | | :--- | :--- | :--- | :--- | | | SPN 97 FMI 3 | Water in Fuel Indicator – High Voltage | Water in fuel filter sensor faulty or actual water contamination. | | | SPN 3242 FMI 4 | Aftertreatment Diesel Exhaust Fluid (DEF) Tank Level – Low Voltage | DEF tank level sensor failure or wiring short. | | | SPN 4360 FMI 15 | SCR System – Reagent Dosing Valve – High Temperature | DPF regeneration interrupted or dosing valve stuck. | | Transmission | MID 138 PID 177 | Transmission Fluid Temperature – Above Normal | Overloaded operation, low fluid, or cooler blockage. | | | MID 140 SID 35 | CVT (Variomatic) Ratio Error | Clutch wear, pressure sensor fault, or calibration required. | | Hydraulics/Electrics | MID 217 SID 247 | Rear Remote Valve – Position Sensor – Out of Calibration | Remote valve lever needs recalibration via SmartTouch. | | | MID 144 PID 168 | Battery Voltage – Below Normal (FMI 1) | Alternator failure, loose belt, or dead cell. |

Often seen on T-series models, this typically points toward hydraulic or transmission malfunctions, sometimes linked to low oil levels. F-Codes (Operational & Brake):

Commonly referred to as EEM3 or EEM4 codes, these relate to the Sisu Diesel engine management system:
