Perhaps nothing. Is the garage detached? What size breaker feeds the garage?

Depending on when it was done and what other services extend to the garage, maybe nothing.

Prior code allowed such a circuit if no other metallic service (metal water pipe,cable TV, telephone) are extended to the garage. Also ground rod(s) required at the garage. Under those conditions the neutral and ground are bonded at that sub panel.

Aha, attached garage, different story. Needs to be a 4 wire circuit, no ground rods, no bond between neutral and ground.

Is there a breaker in the main panel feeding the sub? What size?

Again.......it all depends on when the job was done. For a sub-panel in a detached structure for many years it was code acceptable to run a "3-wire" feeder and bond the neutral. Just like it was code to run a "3-wire" circuit to an electric dryer or range.

SER should have an insulated neutral and a bare ground as well as the two hots.
