21652649 Module | Genuine Volvo Penta Part

🔧 Product Description

Factory-programmed electronic control module for a specific Volvo Penta petrol engine calibration. The module controls fuel delivery, ignition timing, idle strategy, protection functions and onboard diagnostics; modules that look identical are not interchangeable unless the software and engine serial application match.

⚙️ Key Features

• Genuine Volvo Penta programmed control module
• Current replacement for 21367589
• Factory programmed
• Serial-specific calibration
• Requires correct connector, software and engine serial number
• Installation may require programming, configuration or relearn procedures
• System type: Programmed engine control module

🔌 Function

Processes sensor inputs and controls injectors, ignition coils, idle, protection strategies and fault diagnostics.

⚠️ Common Signs of Failure

• No-start or loss of injector/ignition control
• No ECU communication
• Engine enters protection or limp mode
• Water intrusion, corrosion or overheated connector terminals

🛠️ Service Notes

• Isolate the batteries before unplugging or fitting any module, and never disconnect one with the ignition on or the engine running
• Before condemning a module, check its supply, its earth and the harness continuity; a poor earth or a chafed lead gives exactly the same symptoms as a dead unit
• Handle the module by its casing, keep the connector pins clean and dry, and push connectors home squarely until the lock engages — bent or corroded pins cause more trouble than the modules themselves
• Mount it in the original position and orientation using the original brackets or clips, so it stays clear of heat, moving parts and standing water
• Many engine and control modules have to be configured or programmed to your particular engine before they will work correctly, so allow for a Volvo Penta dealer with the correct diagnostic equipment where that applies
