Volvo: SRS reset on 92 Volvo 940, volvo 940, dtcs

Question
How do I reset the SRS fault light on a 92 Volvo 940 Turbo? I replaced a seat belt with the ignition on (to move the seat) and the SRS light came on. I downloaded one solution, dealing with the A and B diagnostic blocks under the hood. The B block has only one contact in it and no button. I tried connecting the wire from the A block and read the code 1-2-2, but I couldn't clear it by holding down the button for 5+ sec as the download said.

Answer
Hello,
The DTCs may be erased only when all have been displayed at least once and the first DTC has been repeated.
Press the test button for at least 5 seconds. The LED will light 3 seconds after the button has been released. Press the button again for at least 5 seconds.
