I had these SRS Airbag System Codes scanned on a car.

B1615 Front airbag sensor (LH)

B1650 occupant classification system malfunction

What are the diagnostic procedures?
Or parts potentially needing to be replaced based on these codes?

Yes, this is the sensor in the passenger seat which has gone bad, here is how to change it out:

B1615: This code usually indicates a malfunction in the front occupant classification sensor.

B1650: This code typically points to a problem with the occupant classification system.
