Go google and type in--- fault code b1650 on toyota 2014 model--and there is a site --www.toyotapart.com which has a pdf down load and explanation of the fault
it concerns the passenger initialization of the air bag systems and how they are locked out if there are no passengers
it requires a special procedure to reset it
it covers recalls as well
I would suggest that you down load the pdf version, study it then take the car to a service dealer senter and have it fixed under warranty

DTC B1650 occupant classification system fault. 2007 DTC B1650 occupant classification system and the vehicle has been in a rear end collision and i tried to have the OCS reset but in vain, please help

If it is like a Chrysler, you will need to go to the dealer and have them redo the OCS. This has to do with the passenger airbag system and how much force it will send the air bag with.

DTC B1650 occupant classification system fault. 2007

If the vehicle has been in a rear end collision, expect this. If not, it just may need to have the Occ Class Sys reset. Toyota Dealer only.
