⚙️ 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

📦 Condition

• Genuine Volvo Penta part

• Supplied in original or equivalent packaging
