- I scanned my car for SRS light and was given code B1650 which says the most common repair is zero point calibration w/B1785 and B1786. It also says other associated ones are preform Occupant Classification System (OCS) initialization and Programmed Passenger Presence (PPS) sensor module w/B1785/B1786. I can't find anything online about these or what to do. I'm sure I can replace the PPS sensor but idk about the zero point calibration or OCS. Any tips or advice?
hey, I think the zero point calibration might require the toyota techstream software to reset that, if it doesn't do it on its own. Should do that by itself. Just replace the bad part, reset the computer by either using your obd2 scanner or disconnect the negative battery cable, wait like 5-10 minutes, reconnect.
I did look up the code and it points at the passenger seat wiring/sensor. And yeah if it was in water, then it could've caused that to be damaged.
Here's what I found are the possible causes..
B1650 TOYOTA Possible Causes
Faulty Occupant Classification System
Faulty Airbags Sensor Assembly Center
Faulty Right Front Seat Wire
Sorry for the late reply.. hope my advice helps ya.
