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
