Honda SRS fault code. Need help deciphering

It’s a '97 CR-V.

SRS light is on and I pulled the codes by jumping the terminals on the SCS connector and counted the blinks.

I got “51”



What does it mean?

5-1 = Internal failure of the SRS unit.

Corrective action = SRS unit replacement.

Sorry, but that’s what my '97 Honda manual says.
