🚤 Compatibility

Typically suits:

• Volvo Penta HPCU-B

• Engine Family: HPCU

⚙️ Key Features

• Identification plug marked ESS-ID6
• Sixth and highest address in the six-plug identification set
• Listed for one HPCU application
• Supplied from the Cables and Fuses group

🔌 Function

Sets a fixed identity on the connector it is fitted to, so the control system knows which unit in the group it is talking to and addresses each one separately.

⚠️ Common Signs of Failure

• Control system reports a missing or duplicated unit address
• Unit drops off the network intermittently, often worse over rough water
• Plug body cracked or the locking latch broken so it backs out of the socket
• Green or white corrosion on the pins when the plug is withdrawn

🛠️ Service Notes

• Identification plugs are not interchangeable between positions - fitting the wrong address is the usual cause of a duplicated unit fault, so record which socket each one came out of before disturbing the loom
• Check the socket pins and the loom connector before condemning the plug; a spread or corroded socket pin gives the same symptoms

📦 Condition

• Genuine Volvo Penta part
• Brand new
• Supplied in original or equivalent packaging
