My SRS code experience

I had replaced my driver side rear window. Afterwards, my Seatbelt light came on. I bought a Peake Reset SRS tool, and 3 codes came up including "System Power". I tried to re-set the alarms with the Peake Research Tool, but they wouldn't re-set. After reading several forums, and ready to rip out seats and panels again, I came upon some VERY GOOD ADVISE: CHECK YOUR BATTERY CHARGE, IT CAN CAUSE ALL TYPES OF SRS ALARMS. So I did and after a 5 hour battery charge, I re-tested and now only one alarm was present. I performed the re-set and the alarm and light went out! Simple. A little knowledge saves a lot of muscle!
