PCS2_a051 warning came up after PCS replacement

[melb7425]

I recently had my PCS replaced a few months ago. Had another PCS2_a051 warning come up, but no noticeable charge difference. Anybody have this issue and had to get another PCS?

Check your invoice and see what rev they put in it last time. I hear the G version is the good one.

Maybe. I was told they are working on a new revision which has an expected August release. They are making me wait for it.

I’ve had the same alert twice pop up in May. My truck was plugged in, but not charging. Both times it went away on its own. My PCS was replaced with Rev F in December.

I’ve also noticed an AC hum when charging. I have a service appointment on the 17th to take a look.

I'm getting the same alert after PCS replacement. I can still charge. Service appointment is for Monday.

Thoughts on my pcs error I see on both tessie and on service mode. I still charge perfectly fine at full speed. Should I schedule a service visit? According to my order parts page and my vin I have 1777777-T2-G installed in my truck from the factory.

I think a051 is a communication error in the
PCS - HVC - BMB communication chain which could be a software bug, wire harness, or device cluster assembly issue (along with the modules themselves).
It's a different thing than the DCAC charging/ outlet failures.
Request a service appointment and they can probably remotely check if it's a bug or hardware issue.
