I'm going to guess it displaced the software update vs replace it. Maybe they will do them both at the same time, but given that the software update requires a battery swap etc. vs this service action which is just a firmware update to specific components.
WE won't really know I guess until someone has the actual instructions.
You're right, we won't know until we know, yet the language in this latest reads as unambiguous to me:
"On January 27, 2023, the service action was paused
in an effort to help improve the customer experience and to avoid requiring additional customers to make repeat trips for service. This recall will replace
the service action..."
The use of "will replace" instead of "be prioritized over" indicates a one-for-one swap. The fact they even bother to mention the service action in the recall letter (twice now) further indicates the recall isn't just displacing the service action, but replacing it – why else mention a non-related service campaign in a recall document?
But again, this begs the questions: •What software was contained in the original service campaign that a revisit would be necessary? •If this is in fact the whole package, can they tune it to be completed in a more expedient manner? •And the 12 volt battery supply question...
Because a couple different service advisors mentioned the addition of a stateside server, and the original email mentioned process improvements, perhaps this was a well -timed opportunity to stand down and retool?
Looking forward to seeing somebody who received the 3.1 update to post their BMS and VFD software version info.
