🔌 Function

The module monitors oil-injection and warning-system inputs, then activates the warning horn circuit when a low-oil or oil-system fault condition is detected.

Common signs of failure:

• Warning horn does not sound during test or fault condition

• Constant false oil alarm

• Intermittent oil warning with verified oil level

• Alarm module fault after sensor and wiring checks

• Oil warning circuit not responding to test input

• Heat or water damage to module casing

• Incorrect alarm behaviour after engine harness inspection

📦 Condition

• Genuine used part

• Removed from running engine where applicable

• In good working condition unless otherwise stated
