B0019 – Passenger Frontal Deployment Loop Stage 1

B0019 Possible Symptoms

Air Bag Warning Light ON

B0019 Possible Causes

Faulty Passenger Frontal Module,Passenger Frontal Module harness is open or shorted,Passenger Frontal Module circuit poor electrical connection,Faulty Sensing and Diagnostic Module (SDM)

B0019 Description

During a side or frontal crash of sufficient force the inflatable restraint Sensing and Diagnostic Module (SDM) will allow current to flow through the deployment loop in order to deploy an inflatable restraint module. There are 2 shorting bars used within the module connector which will short together both high and low circuits, when the connector is disconnected. This will help to prevent unwanted deployment of the inflator module during servicing.
