Code B1019 2014 GMC Sierra Description

The Inflatable Restraint Sensing and Diagnostic Module (SDM) monitors the number of safety components installed on the vehicle. When the ignition is turned ON, the Inflatable Restraint Sensing and Diagnostic Module evaluates the number of safety components installed and compares it to the number of components the Inflatable Restraint Sensing and Diagnostic Module expects to see on the vehicle with its current calibration. If there is a mismatch between the detected components and the components programmed with the Inflatable Restraint Sensing and Diagnostic Module calibration, Diagnostic Trouble Code (DTC) B1019 will be set. The components (if equipped) that the Inflatable Restraint Sensing and Diagnostic Module will detect include inflatable restraint deployment loops, impact sensors, passenger presence system components, seat position sensors, disable switches, and seat belt switches.

Code Tech Notes

B1019:3A SDM System Configuration Error Incorrect Component Installed

Diagnostic Trouble Code (DTC) B1019 can be set after the Inflatable Restraint Sensing and Diagnostic Module (SDM) has been replaced and/or reprogrammed before the setup procedure is completed. The setup procedure cannot be completed if DTC B1019 is set as current or history. If a short or open is detected in a deployment circuit prior to the setup procedure being performed, the inflatable restraint sensing and diagnostic module will set DTC B1019.

What is the Cost to Diagnose the Code?

Labor: 1.0

To diagnose the B1019 2014 GMC Sierra code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.

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.
