Code B1019 Description

The B1019 diagnostic trouble code (DTC) indicates that there is a configuration error within the Sensing and Diagnostic Module (SDM) system of the vehicle. The SDM system is responsible for monitoring and deploying the airbags and seat belt pretensioners in the event of a collision. When a configuration error occurs, it means that the system is not properly set up to perform its intended functions. This can lead to serious safety concerns as the airbags may not deploy or deploy incorrectly during a crash, putting the occupants at risk.

Tech Notes for B1019

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.

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.
