Center Air Bag Sensor Assembly (Prius)

Center air bag sensor assembly delivers an input signal to Hybrid Vehicle (HV) control Electronic Control Unit (ECU) if an airbag is deployed. Hybrid vehicle control ECU is referred to as HV ECU. The HV ECU then delivers input signal to Engine Control Module (ECM). If air bags are deployed, ECM will stop fuel pump operation by opening the circuit opening relay. This operation is referred to fuel cut control. If fuel cut control has been activated, turning ignition switch from OFF position to ON position cancels the fuel cut control operation and fuel pump will operate. Center air bag sensor assembly may also be referred to as air bag sensor assembly.
