Scope
This document provides vehicle-level data collection, data analysis, and data verification procedures that may be used to verify that an instrument under test (IUT) satisfies the vehicle-level requirements specified in the SAE International (SAE) J2945/1 standard. For the purposes of this recommended practice, “vehicle-level requirements” primarily consist of those requirements which can be verified external to the vehicle. The IUT for these procedures is a configured dedicated short range communications (DSRC) vehicle-to-vehicle (V2V) device as defined in SAE J2945/1 and is installed on a light vehicle. While the IUT is conceptually separated from the vehicle it is installed on, the tests outlined in this document are primarily vehicle-level so the terms “vehicle” and “IUT” can generally be considered interchangeable. Additionally, non-vehicle-level complementary tests, not included in this document, are required to verify that the entire set of requirements specified in SAE J2945/1 is satisfied.
This document also includes a traceability matrix to provide traceability between SAE J2945/1 sections and the test procedures. This can be used to ensure thoroughness of testing coverage.
The SAE J2945/1 sections that are included in the scope of this revision in this document are indicated in Table 1. SAE J2945/1 major section numbers that are indicated as N/A do not contain any requirements (subsections may include requirements). Sections that are not in scope, such as standards profiles, are expected to be tested and verified as part of device-level certification, prior to vehicle-level testing, which is the primary focus of this document.
Rationale
This document provides companion vehicle-level test procedures to the SAE J2945/1 Standard to support validation and compliance testing. The document will be a recommended practice in which the test methodologies are specified for validation of both functional and performance requirements in SAE J2945/1. Sample test results based on the test procedures are also being included for informational purposes.

* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
