DTC B1150/23 Occupant Classification System Malfunction
DESCRIPTION
The occupant classification system circuit consists of the center airbag sensor assembly and the occupant classification ECU.
If the center airbag sensor assembly receives signals from the occupant classification ECU, it determines whether or not the front passenger airbag, the front seat side airbag RH, and front seat belt pretensioner RH should be operated.
DTC B1150/23 is recorded when a malfunction is detected in the occupant classification system circuit.
