Proposal to remove subjectivity and clarify manufacturer requirements for demonstrating equally effective triggering performance in vehicles with a maximum mass between 8,000 and 12,000 kg.

Proposal to amend UN R169 by inserting definitions for non-volatile and volatile memory, and modifying the Last Stop trigger criteria. The amendment allows threshold criterion (a) data to be written to volatile memory only, transferring to non-volatile memory when other triggers occur or the master control switch deactivates. This reduces memory wear in vehicles with frequent stops exceeding 20 seconds.
