Review of the informal group discussions through day 2 of the group session.

Proposal to clarify ADS Active Mode and methods to activate ADS using test equipment or by modifying software of in-vehicle ADS-related ECUs, clarify test objects for ESA at component-level or system-level, and clarify test methods when ADS cannot be activated in an anechoic chamber, when testing in a non-active state using warning indicators or diagnostic functions, or when errors occur upon activation of ADS. This is a preliminary proposal intended for presentation at IWG EMC meetings in Autumn 2026.

Proposal for conducting the ADS Active Test Specified in Annex 6 to clarify ADS Active Mode, clarify methods to activate ADS using test equipment or by modifying in-vehicle ADS-related ECU software, clarify test objects for ESA at component-level or system-level, and clarify test methods when ADS cannot be activated in an anechoic chamber, including testing in a non-active state using warning indicators and diagnostic functions, and testing when errors occur upon ADS activation. The proposal defines ADS Active Mode as representative ADS functions remaining operational using sensors whose inputs can be simulated within the anechoic chamber environment, with alternative test methods including application based on ESA or subsystem test results, testing with ADS not activated using steady-state driving conditions with pass/fail criteria verifying no communication errors, ECU malfunction, freeze, shutdown, or ADS system malfunctions occur, and testing with simulated sensor outputs using data from real-world driving or representative driving scenarios.
