NOTE: A Special Service Message is a formal communication issued by Land Rover and carries
the same importance of a Technical Service Bulletin. An SSM is a quick method of
communicating "Need To Know" information to the technical service community. SSM's may
be issued in advance of a technical bulletin or may be the only communication on a given
topic. All information contained in Land Rover technical communications are intended for
use by trained, professional technicians with the knowledge, tools, and equipment required
to complete the procedure correctly and safely. It informs the Technicians of conditions that
may occur on some vehicles, or provides information that could assist in correct vehicle and
