3.1 Recall plan

a specific implementation plan developed by the producer for the recall activity

NOTE: The contents of the implementation plan include but are not limited to producer information, recalled product information, recalled product scope, defect description and possible consequences, recalled maintenance measures, emergency response methods, product improvement measures, and recalled notification methods. [Source: GB/T 39603-2020, 3.2, modified]

3.2 Recall report

the act that the producer submits the recall plan in accordance with the regulations of the competent authority

3.3 Recall number

a set of normalized codes for recall campaign management

3.4 Recall process tracing

the activities to track and trace the implementation of product recalls by recording the time, place, measures and other information of the recall of defective products

3.5 Traceability system of recall process

a system that, based on file records, computer software, hardware equipment and communication network, carries out information management on the data related to the recall process traceability

3.6 Enterprise terminal of traceability system

a system that carries out product recall implementation information collection and review, and synchronizes data to the traceability system management end

NOTE: The enterprise terminal of traceability system in this document is an integral part of the traceability system of the recall process of automobile products, which is managed by the producer of automobile products.

3.7 Management terminal of traceability system

a system that receives, verifies, stores and counts the product recall implementation information synchronized by the enterprise end of the traceability system, supports activities such as monitoring and alarming of the running status of the connected traceability system at the enterprise end

NOTE: The management terminal of traceability system in this document is an integral part of the traceability system for the recall process of automotive products and is managed by the automotive product recall technical organization.

3.8 Service terminal of traceability system

a system that provides recall information query, push and data sharing services to government departments, industry enterprises, the public and other relevant parties […]

5.2.3 Functional requirements for service terminal of traceability system

5.2.3.1 The service terminal of traceability system shall provide the public with vehicle recall information query services.

5.2.3.2 The service terminal of traceability system shall push vehicle recall information to subscribers. Improve the efficiency of vehicle recall information dissemination.

5.2.3.3 The service terminal of traceability system can share relevant vehicle recall information with relevant parties.

7.1 Data synchronization method

The recall process information is transmitted between the enterprise terminal and the management terminal of the traceability system through a data interface.

7.2 Data synchronization content

The contents and requirements of the recall process information synchronized from the enterprise terminal to the management terminal of the traceability system are as follows:

- Recall number: shall meet the requirements of GB/T 39061;

- VIN of the recalled vehicle: shall meet the requirements of GB 16735 and GB 16737;

- Time for recall: shall meet the requirements of GB/T 7408;

- Vehicle maintenance record number: shall be accurate, true and unique;

- Name or number of recall dealer: shall be consistent with the recall filing information;

- Contact details for recipients of recall notices.

7.3 Data synchronization time

After the implementation of the vehicle recall is completed, the producer shall synchronize the recall process information to the management terminal of traceability system through the enterprise terminal of traceability system no later than 24:00 of the next day.

7.4 Data storage requirements

Traceability system data storage meets the following requirements:

a) The enterprise terminal of traceability system shall be kept for no less than 10 years;

b) The data on the management terminal of traceability system shall be kept permanently;

c) The traceability system management shall adopt distributed storage and provide backup.

7.5 Data synchronization interface requirements

7.5.1 Interface protocol

The traceability system data synchronization interface protocol shall meet:

a) Adopt HTTPS transmission protocol;

b) Use POST request method;

c) Data format is JSON format;

d) Character encoding is UTF-8.

7.5.2 Exchange process

The producer opens the data interface on the enterprise terminal of the traceability system and authorizes the data interface access authority to the management terminal of the traceability system.

The management terminal of traceability system sends a data synchronization request message to the enterprise terminal of traceability system. […]

8.3 Data sharing interface requirements

8.3.1 Interface protocol

The traceability system data sharing interface protocol shall be implemented according to 7.5.1.

8.3.2 Exchange process

The data interface of the service terminal of traceability system is opened. Grant data interface access to data users.

The data user sends a data synchronization request message to the service terminal of traceability system. The service terminal of traceability system shall respond to the request message within 3s. Synchronize vehicle recall information with data users. If the data user does not receive the response message within 3s, it shall interrupt the transmission and make a new request.

The service terminal of traceability system sends the vehicle recall information to the data user. After the information is sent successfully, a success ID is returned.

8.3.3 Message structure

The data sharing request message and response message structure between the data user and the service terminal of traceability system shall comply with the provisions of Annex C.

9.1 Performance requirements for enterprise terminal of traceability system

The enterprise terminal of traceability system shall meet the following requirements:

a) The average response time of the data interface does not exceed 5s;

b) The data interface throughput rate is not less than 500kB/s;

c) The annual downtime does not exceed 3% of the year.

9.2 Performance requirements for management terminal of traceability system

The management terminal of traceability system shall meet the following requirements:

a) The average response time of the data interface does not exceed 5s;

b) The data interface throughput rate is not less than 2000kB/s;

c) The annual downtime does not exceed 1% of the year.

9.3 Performance requirements for service terminal of traceability system

The service terminal of traceability system shall meet the following requirements:
