After not being able to find anything useful about this problem, I decided to make this video to explain how to fix the common issue of the SRS (airbag) light coming on in many 2001-2005 Honda Civic and possibly other Honda and Acura cars in and around those years. Note that in the US apparently this is covered under a lifetime seatbelt waranty but in Canada it's not covered.
Also, I have included a partial codes list for the SRS light in case you get a different code than the typical 9-3. If your code is not 9-3 then this will probably not fix your problem. These are codes that I found online, I do not have the service manual (or the pages referred to in the list).
1-1 Open in driver's airbag inflator (see page 23-55)
1-2 Increased resistance in driver's airbag inflator (see page 23-55)

1-4 Short to power in driver's airbag inflator (see page 23-59)
1-5 Short to ground in driver's airbag inflator (see page 23-61)
2-1 Open in front passenger's airbag inflator (see page 23-63)
2-2 Increased resistance in front passenger's airbag inflator (see page 23-63)
2-3 Short to another wire or decreased resistance in fr passenger's airbag inflator (23-64)
2-4 Short to power in front passenger's airbag inflator (see page 23-66)
2-5 Short to ground in front passenger's airbag inflator (see page 23-67)
3-1 Open in left side seat belt tensioner (see page 23-69)

4-4 Short to power in left side seat belt tensioner (see page 23-81)
4-5 Short to ground in left side seat belt tensioner (see page 23-83)
5-_ Internal failure of SRS unit (see page 23-85)
6-_ Internal failure of SRS unit (see page 23-85)
7-_ Internal failure of SRS unit (see page 23-85)
8-_ Internal failure of SRS unit (see page 23-85)
9-1
Internal failure of the SRS unit. If intermittent, could mean internal failure of the unit or a faulty indicator light circuit. Refer to Troubleshooting Intermittent Failures (see page 23-38). Otherwise see page 23-85.
9-2
Internal failure of the SRS unit. If intermittent, could mean internal failure of the power supply (VB line). Refer to Troubleshooting Intermittent Failures (see page 23-38). Otherwise see page 23-85.
9-3 Faulty driver's seat belt buckle switch
9-6 Faulty left front sensor (see page 23-88)
9-7 Faulty right front sensor (see page 23-91)
10-1 Seat belt tensioners (and airbag(s)) deployed (see page 23-85)
