Air Bag Warning Light ON


B0025 Possible Causes


Faulty Right Roof Rail Air Bag,Right Roof Rail Air Bag harness is open or shorted,Right Roof Rail Air Bag circuit poor electrical connection,Faulty Sensing and Diagnostic Module (SDM)


B0025 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 the right roof rail air bag. The SDM performs continuous diagnostic tests on the deployment loops to check for proper circuit continuity and for shorts to ground or voltage. A shorting bar is used within the right roof rail air bag connector which will short together both high and low circuits when the connector is disconnected. This will help to prevent unwanted deployment of the air bag during servicing.
