- Content
- This document describes the functional safety (FuSa) assurance data to be included when communicating safety-related A_PDUs using either the Multi-PG service or the FD Transport service within an SAE J1939-22 protocol stack. It specifies the following:
-
The parameters that make up the FuSa assurance information
-
The behavioral requirements when producing and consuming FuSa assurance information
-
The technical requirements for different FuSa profiles intended to meet different application requirements
-
The trailer formats for the different FuSa profiles that can be incorporated into Multi-PG and FD Transport services
This document does not specify the assignment of a FuSa profile to any values of the TOS and TF fields when using the Multi-PG service, or to any value of the AD TYPE field when using the FD Transport service; instead, SAE J1939-22, or an OEM in the manufacturer-specific ranges of these fields, specifies the assignments for these fields. -
