INTRODUCTION
Consumer products are often repaired by service workshops, which service a wide range of
products developed by different manufacturers.
For highly complex products, fault diagnosis becomes increasingly difficult and time consuming.
To facilitate diagnosis, manufacturers often develop built-in diagnostic software that
communicates with an external diagnostic unit through a service diagnostic interface (SDI).
To avoid the need for a service workshop to purchase several different diagnostic units from
different manufacturers for different products, a standardized SDI is proposed for use by all
manufacturers of any products requiring a diagnostic interface. The result will be that only one
SDI is needed in the service workshops.
The SDI should be suitable for diagnosis in a facilities or household appliances network in which
different products from different manufacturers are connected together. The interface should
also allow for future development.
The standard SDI should
– be usable in future products,
– be easily connectable to a product or a network,
– be inexpensive,
– not limit product design.

SERVICE DIAGNOSTIC INTERFACE FOR CONSUMER
ELECTRONICS PRODUCTS AND NETWORKS –
IMPLEMENTATION FOR ECHONET
1 Scope
This International Standard specifies requirements for service diagnostic software to be
implemented in products that incorporate a digital interface. It does not specify requirements for
carrying out remote diagnosis or for manufacturer-dependent software.
The SDI (Service Diagnostic Interface) requires an external controller (exclusive or
general-purpose/PC) into which service diagnostic software can be loaded. Part of the controller
software should be standardized while another part of this controller software should be unique
to the manufacturer.
To reach a common approach in servicing all products from all manufacturers, it is necessary to
standardize specific items to be tested in products and in controllers’ diagnostic software.
The SDI is based upon the ECHONET specification version 2.11, ECHONET Lite specification
version 1.01 and APPENDIX Detailed Requirements for ECHONET Device objects Release B
because this interface will be used in future products. The use of this connection and existing
communication protocols enable implementation in products at low cost, with maximum
flexibility and efficiency.
The SDI consists of
• specific hardware and software requirements of the device under test (DUT);
• specific requirements of the controller:
– the service software;
– an ECHONET interface;
• the connection between the controller and the DUT.
This standard provides the minimal requirements necessary to carry out computerized diagnosis.
It covers the standardized software of the controller as well as the standardized software and
provisions in the DUT.

4 Different types of service diagnostics
4.1 Stand-alone products
For stand-alone products, a connection is made between the diagnostic controller and the DUT,
where the DUT is from any manufacturer and of any type.
4.2 Facilities or household appliances network
In a facilities or household appliances network, a connection is made between the diagnostic
controller and a network of facilities or household appliances. Several different facilities or
household appliances are interconnected and not all of them are necessarily from the same
manufacturer.
In this case, the SDI shall list the products on the network, detect which facilities or appliances
are causing problem, and diagnose the product concerned.
4.3 Remote diagnosis
In addition to the configurations described in 4.1 and 4.2, a link can be made (for example, via
telephone, the Internet, etc.) between the diagnostic controller in the workshop and a
DUT/network at the customer’s home. Therefore, if a product has both an ECHONET interface
and a remote connection capability, this product should be able to transfer the diagnostic data,
as described in this standard, through the remote connection.
5 SDI requirements
