Description / Abstract:

This document provides detail for incorporation of Test Bypass (TB) functionality in SPA components and systems, and describes the messaging protocol for TB. Test Bypass is the mechanism by which test data may be injected into the running SPA system, or by which operational data may be extracted from various test points within the system during integration and test. The concept of TB was developed to further enhance the rapid assembly, integration, and test (AI&T) for SPA compliant vehicles. More general discussion on TB functions and interfaces is available in the SPA Guidebook.

This document defines the current state of practice for TB. This standard is applicable to all SPA devices and systems that support a bypass function for testing purposes. Further development of this method will be updated within this standard. Other developments that address testing functions will be defined in other documents.
