hds will show you the weight value when you reset the opds. if you dont see weight value change when some one set on the seat then opds fault,if you see weight value change then try anther srs unit i have seen problem in srs that give you opds fault

Could be a bad srs unit, bad opd unit, or simply bad weight sensor(s). Have to diagnose and pinpoint man.

Did try SRS ,OPDS ,come back with same DTC. did try to disconect OPS , than shows new DTC's.When disconect SWS from OPDS box, makes no change.My original question-- is how to check weight sensors ?how they work ?

Replaced seat.I couldn't figure out how to check sensor it self.Problem in sensor(s), I am 100 pct. positive, not in wiring.It fail at some reason.
