Description

Volvo Penta After-Treatment System Workshop Manual Groups 2 & 3

This workshop manual covers the Volvo Penta After-Treatment System (EATS) for Groups 2 and 3. Publication number 47711053, dated 12-2018. It is written for Volvo Penta workshops and qualified personnel who service, diagnose, and repair the SCR/AdBlue/DEF exhaust after-treatment system on supported engines.

The document brings together general information, safety instructions, component replacement procedures, fault tracing, diagnostic trouble code descriptions, electrical measurements, VODIA test procedures, and wiring diagrams for the ACM (After-treatment Control Module) and its connected components.

Across these chapters, the manual gives a technician the complete diagnostic and repair picture for the Volvo Penta EATS: how the SCR system is laid out, what each DTC means, how to test individual sensors and actuators with a multimeter and break-out box, how to replace the tank, pump, dosing valve, heated hoses, and sensors, and how to run the VODIA tests that confirm the repair. Fault code tables list SPN, FMI, DTC conditions, probable causes, and step-by-step actions, while the measurement tables give expected voltages and resistances at the ACM connector for level/temperature sensors, dosing valve, pump pressure sensor, reverting valve, and tank heating valve.

What This Manual Helps You Do

With this Volvo Penta After-Treatment System workshop manual, a qualified technician can:

• Identify and interpret EATS diagnostic trouble codes (P-codes and U-codes) using the SPN/FMI tables.
• Trace faults through the ACM connector with the break-out box and multimeter, using the supplied measurement tables.
• Replace the AdBlue/DEF tank, tank fittings, pump unit, dosing valve, pump filter, heated hose, exhaust temperature sensor, and solenoid valve with correct torque values and safety steps.
• Clean a contaminated AdBlue/DEF tank and decide whether components must be replaced or can be cleaned, based on contamination level.
• Check for diesel or oil contamination in the AdBlue/DEF solution and verify urea concentration with a refractometer.
• Run VODIA tests: Urea Pressure Build Up Test, Urea Dosing Test, Urea Hose Electrical Heating Activation, Urea Heating Valve Diagnostic Test, and Urea forced blowout.
• Understand the EATS inducement strategy (EU and EPA/CARB) for low tank level, high temperature, quality, and component faults.
• Read the ACM2 pump wiring diagram and the SCR system schematic to trace electrical and fluid paths.

Why This Manual Matters

The Volvo Penta after-treatment system is sensitive to incorrect AdBlue/DEF quality, contamination, and electrical faults. Using the correct DTC information and test procedures avoids unnecessary component replacement and prevents damage to the SCR catalyzer. The safety section also covers the specific handling requirements for AdBlue/DEF, SCR catalyzer, and particulate filter, which protects both the technician and the system.

This is a workshop-level document. It assumes the reader has fundamental knowledge of the product and can carry out mechanical and electrical work to trade standard. It is not a beginner’s guide.
