21180731 Alarm Kit | Genuine Volvo Penta Part

🔧 Product Description

A genuine Volvo Penta malfunction-indicator alarm kit that adds both a visual MIL warning lamp and an audible alarm to a compatible engine-management system. It alerts the operator when the electronic control system detects an emissions, sensor or engine-control malfunction. The kit is installation- and harness-controlled rather than mechanically engine-controlled. Connector style, system voltage and the presence of a compatible MIL output must be confirmed from the engine wiring parts list for your engine.

🚤 Compatibility

• Engine Family: V
• HP Range: 200-430 HP
• Year Range: Approximately 2000s - 2010s

🔌 Function

The kit converts the engine-control malfunction output into a clearly visible warning lamp and audible alarm at the operator station.

⚠️ Common Signs of Failure

• A stored engine fault does not produce a visible or audible warning
• Lamp remains illuminated without a current fault
• Buzzer is silent or sounds continuously
• Connector corrosion causes intermittent warnings
• Incorrect voltage or wiring logic damages the warning circuit

🛠️ Service Notes

• Confirm the presence of a compatible MIL output on your specific engine-control system before ordering - the fitment note itself flags that connector style and voltage must be checked against the wiring parts list for the broad V6/V8 range this covers
• Combines a lamp and a sounder in one kit - if you are replacing only one half of an existing warning arrangement, confirm you actually need the combined kit rather than a lamp-only or sounder-only equivalent
