B0014 2018 GMC Sierra Code - Driver Seat Side Air Bag Deployment Loop

Quick Answer

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. Common causes include Faulty Driver Seat Side Air Bag, Driver Seat Side Air Bag harness is open or shorted, Driver Seat Side Air Bag circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code B0014 2018 GMC Sierra Description

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 disconnected. The shorting bar helps prevent unwanted deployment of the inflator module during servicing. The SDM performs a 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 are below specifications the code B0014 and the appropriate symptom byte will be set.

Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” Service

Never probe the electrical connectors on air bag, side air curtain modules or seat belts.
Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive load limiting retractors, safety belt inflators, or probe the electrical connectors.
Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 minutes. For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.

Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.
