Peake SRS tool purchased, used, help.

[DueceMcCracken]

So I bought the peake tool, I used it, I cleared a few codes, then one came back 100 miles later.

Driver side seatbelt circuit?

When I turn on my car my seatbelt light is lite for a few seconds and then just turns off regardless of me wearing the seatbelt.

The previous owner did some electrical stuff, LCD's, stereo, etc.

So is there a seatbelt connector or something I should check out?

What could cause this?

I have limited computer access so please excuse my lack of searching.
