If the fault is not included in this table, please contact your local BTSR reseller, giving a detailed
description of the kind of fault and the conditions in which it occurred. In the case where the BTSR
Technical Service intervention would be required, before calling it is suggested to take note of the
code printed on the faulty sensor(s) and/or on the SMART 200 MTC terminal, as this information will
make diagnoses for the BTSR technicians easier.
Example:
Sensor Code:
V8 S3.0 0501 00874
