CUSTOMER CONCERN The SRS warning lamp is on with DTCs B1782 and B1650. CAUSE Scan-data seat-weight values isolated a failed left-rear occupant-classification sensor in the passenger seat assembly. CORRECTION Remove and replace the passenger-seat assembly containing the failed occupant-classification sensor, perform occupant-classification zero-point calibration, clear DTCs B1782 and B1650, and verify the SRS warning lamp remains off.
