## ⚙️ Key Features

-   Genuine Volvo Penta software-programming reference
-   Used in selected SCR / exhaust-aftertreatment systems
-   Associated with control-unit and SCR pump-unit programming
-   Engine- and emissions-calibration specific
-   Not supplied as a standalone physical part
-   Engine type: 10.8L inline six-cylinder turbocharged industrial diesel with SCR aftertreatment

## 🔌 Function

Loads the correct engine- and emissions-specific parameters into the SCR control unit or associated aftertreatment component so dosing, monitoring and diagnostic functions operate as calibrated.

## ⚠️ Common Signs of Failure

-   SCR or emissions-system faults after control-unit replacement
-   Incorrect or missing dosing-system parameters
-   No communication with the programmed aftertreatment component
-   Persistent calibration or configuration fault codes
-   Engine derate caused by incomplete or mismatched software

## 🛠️ Service Notes

-   Software parts are engine and installation specific — the engine serial number and the software level currently installed must be established before ordering or loading
-   Loading is done through Volvo Penta diagnostic equipment by an authorised dealer; this is not something that can be fitted on board without that access
-   Have the existing parameter settings and the fault memory read out and recorded before any update, so the installation can be restored afterwards
-   Make sure the batteries are in good condition and a stable supply is maintained throughout, and do not interrupt the process once it has started
-   After loading, clear and re-read the fault memory and check that engine and control functions behave correctly before the boat goes back into service
