Known problem for SRS light might be cause by bad seat belt buckle. Honda seat belt buckle and belts are lifetime warranty(not cover if broken because of abuse). Have your honda dealer scan it for code. They might charge you $55 to scan for the code(ex:09-3 driver seat buckle failure), but if it is a for buckle or belt code then everything is free including the scan(labor and part).
good luck

Your 1991 model Accord has automatic front retracting shoulder belts and, more than likely, the power retractor motor has gone bad on the passenger side front. If the shoulder seat belt is not in the retracted position, up close against the seat, when the car is running, the seat belt light will stay lit on your dash. Have the seat belt motor inspected and replaced if necessary.

It is a wear and tear factor on the belts and messing with them can only lead to problems with safety and testing

have your brakes checked. the seat belt may be covered under warranty, ck with the dealer. I worked at a Honda Dealer in the 80's and I think their seat belts were covered for the life of the car. I could be wrong
