Engine oil pressure warning lamp
The engine oil pressure warning lamp within the instrument pack utilises a red LED and a clear legend. The LED
illuminates when the engine oil pressure is below the specified pressure (see table), providing the driver with a visible
warning that the engine oil pressure has fallen below the specified minimum reading.
There is no self-test performed at ignition on for this warning lamp.
The power input for the LED is supplied by the instrument pack via fuse 27. The oil pressure switch located on the
engine provides the earth path to illuminate the warning lamp, it will remain illuminated until the engine is started and
the oil pressure exceeds the appropriate threshold and opens the switch contacts.
