B0014 Chevrolet Left Side Deployment Loop
– Faulty Sensing and Diagnostic Module (SDM)
During a side or frontal crash of sufficient force the inflatable restraint Sensing and Diagnostic Module (SDM) will allow current flow through the deployment loop in order to deploy the side impact module. A shorting bar is located in the electrical connector of the side impact module. The side impact module high control circuit and low control circuit are shorted together by the shorting bar when the electrical connector is disconnect. The shorting bar help prevent unwanted deployment of the inflator module during servicing.
The SDM performs continuous diagnostic test on the deployment loops to check for proper circuit continuity and for shorts to ground or voltage. If the results of any deployment loop circuit test is below specifications the code B0014 Chevrolet and the appropriate symptom byte will set.
