a vehicle 60 days after WRS1 is completed.

Issue Description

WRS1 is the VAL check for battery state of health for
vehicles assigned to ARB6 Recall, and WSA1 is the
follow up for WRS1, so that vehicles can be monitored every 60 days and so that the PC can be paid for
the monitoring.
ARB6 and ARB7 are conducted in 2 phases:
Phase 1: The battery SoH check - for ARB6 this is
done via WRS1/WSA1, whereas for ARB7 it is conducted via OTA data. If batteries fail the check and
need to have modules replaced, they will be added to
ARB5 Recall.
Phase 2: Ultimately, ARB6 and ARB7 final remedy
will be to install optimized BMCe software on the affected vehicles, which is expected in Q1 2025. ARB6/
ARB7 should not be closed on the affected vehicles
until that time.
