The SRS is not something you should touch or fix via DIY. Unless you know exactly what you're doing, messing with it could lead to injuries and possibly death if the bags accidentally deployed while you're in its path. Best leave it to the pros.
usually the SRS is connected with the seatbelts, but still a thing to consider since electrical yan.The best thing to be certain is to bring it to casa and have their computer diagnostic check it, sana may naipit lang dyan or what, before saken kase ABS lang lagi nailaw sa odyssey ko and their diagnostic is always reliable, sensor malfunction, nung napalitan, wala na problem.
