🔌 Function

Reads the engine's sensors and controls fuelling, timing and the protection shutdowns so the engine holds its rated output.

⚠️ Common Signs of Failure

• Engine will not start, or cuts out, with nothing wrong at the fuel side
• Engine will not reach its rated output or holds a reduced power setting
• Alarms or warning lamps with no matching sensor fault
• Instruments dropping out or reading erratically
• Corrosion or water tracking in the unit's connectors

🛠️ Service Notes

• The rating is what selects this unit: sibling 3819890 covers 175 kW at 2400 rpm and 1085 Nm, and fitting the wrong one leaves the engine on the wrong power curve
• Confirm the rating from the engine plate before ordering, since several units in this group share the same 1.146 kg weight
• Isolate the batteries before unplugging it, and check the harness and earths before condemning the unit
