DESCRIPTION AND OPERATION

Transfer box neutral warning lamp

The transfer box neutral warning lamp illuminates to inform the driver that the transfer box is in neutral. The warning 
lamp utilises an amber LED with a clear legend which is to ISO design standards. There is no self-check for this 
warning lamp. If the transfer box neutral warning lamp is illuminated the audible warning speaker will also chime.

There are two configurations for this warning lamp:

l

NAS, Canada and Japan = warning lamp enabled.

l

Rest of World = warning lamp disabled.

The instrument pack provides the power input and the BCU provides the signal to illuminate the warning lamp. The 
transfer box in neutral information is provided by a switch on the transfer box, this sends an analogue signal to the 
BCU. The BCU commands the warning lamp on using the serial link to the instrument pack.
