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

Category : Electrical
Symptom : 208000 Climate Control
Content : Issue: A customer may report that one or more of the
capacitive buttons on the lower Interactive Control
Display Module (ICDM) are activating involuntarily
when not selected. Affecting InControl Touch Pro Duo
infotainment systems only.
Cause: An aftermarket device placed in close
proximity of the lower screen causing electrical
interference with the buttons on the ICDM. An example
of such a device could be an air ionizer.
Action: If such a device is not evident in the vehicle,
please establish with the customer if they use any
device other than a mobile phone that may interfere
with the operation of the ICDM and ask if they can
remove it from the vehicle while continuing to monitor
for a re-occurrence of the concern. If the concern
returns without the presence of any aftermarket
accessory continue with diagnosis using Pathfinder and
with reference to the TOPIx Workshop Manual.
Note: If the concern appears while a Land Rover
approved portable accessory is in use, please submit an
Electronic Product Quality Report.
