SSM 49758 - 2021 Mustang Mach-E - 28 April 2021 - P0AA6 In Battery Energy Control Module (BECM)

Some 2021 Mustang Mach-E vehicles may exhibit an illuminated Powertrain Malfunction (wrench)indicator with diagnostic trouble code (DTC) P0AA6 stored in the Battery Energy Control Module (BECM). Because of the importance of the Mustang Mach-E early experience, please contact the technical assistance center for diagnostic support.

END SSM

This is really odd. No diagnostic support...just saying to contact the hotline immediately. This is the same voltage isolation fault code that @westcoastgr8 had. I guess others are seeing the same issue?

There was another SSM released related to FDRS not showing modules to update as part of an SSM because they were updated at the factory or OTA.

I thought I had a HVBJB issue, and they are currently replacing the BECM which is part of 22B08 recall coming out this week. There are other threads on this.
Only a two week service recall (I hope).
