Code B1019 2017 GMC Sierra Description
The B1019 diagnostic trouble code (DTC) for a 2017 GMC Sierra indicates a SDM (Sensing and Diagnostic Module) system configuration error. The SDM is a crucial component of the vehicle's airbag system, responsible for monitoring various sensors and deploying airbags in the event of a collision. When this code is triggered, it means that the SDM has detected a fault in its configuration, which could potentially compromise the proper functioning of the airbag system.
Common Causes of B1019 2017 GMC Sierra
- Faulty SDM module
- Damaged wiring or connectors in the airbag system
- Software glitches in the SDM module
- Malfunctioning sensors that provide data to the SDM
- Impact or collision that may have damaged the airbag system components
Symptoms of B1019 2017 GMC Sierra
- Airbag warning light illuminated on the dashboard
- Inoperative airbags or seat belt pretensioners
- Erratic behavior of airbag system (e.g., random deployments)
- Loss of communication with the SDM module
- Stored fault codes related to the SDM system
How to Fix B1019 2017 GMC Sierra
- Begin by conducting a thorough diagnostic scan to retrieve the specific fault codes and pinpoint the exact cause of the SDM system configuration error.
- Inspect the wiring and connectors in the airbag system for any signs of damage or corrosion. Repair or replace as necessary.
- Check the sensors that provide data to the SDM for proper operation. Replace any faulty sensors.
- If the issue lies with the SDM module itself, it may need to be reprogrammed or replaced with a new unit.
- Once the repairs are completed, clear the fault codes and perform a test to ensure that the SDM system configuration error has been resolved.

Tech Notes for B1019 2017 GMC Sierra
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.

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.
