Trailer warning lamp
The trailer warning lamp within the instrument pack utilises a green LED and a clear legend. When a trailer is fitted to the vehicle, and the direction indicators are operated, the BCU detects additional current draw and illuminates the LED, providing the driver with a visible warning.
When the ignition is switched on the BCU illuminates the LED to provide a self-check, providing there is no fault it will remain illuminated for 3 seconds or until the ignition is switched off. This self-check is every time the ignition is switched on, not only if a trailer is connected.
The power input for the LED is supplied by the instrument pack via fuse 13. The BCU provides the earth path to illuminate the warning lamp.
