WARNING: This page is about a different car, the 2012 Buick Regal. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:

DTC B1019 can set after the 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 SDM will set DTC B1019.

  1. Ignition ON.
  2. Verify no other SDM DTCs are set.
    • If no other SDM DTCs are set 
  3. Verify the impact sensors called out in the scan tool data list match the number of actual impact sensors installed on the vehicle.
    • If the number of impact sensors do not match 
    1. Verify the correct SDM calibration file is loaded in the SDM.
      • If the SDM calibration file is correct and the vehicle contains an incorrect number of sensors, indentify which sensors are missing to make the vehicle match the SDM impact sensor calibration scan tool data list.
      • If the calibration file is incorrect
    2. Reprogram the SDM. Refer to Inflatable Restraint Sensing and Diagnostic Module Programming and Setup
    • If the number of impact sensors match 
  4. Verify the enabled deployment loops called out in the scan tool data list match the deployment loops installed on the vehicle.
    • If the number of enabled deployment loops do not match 
    1. Verify the correct SDM calibration file is loaded in the SDM.
      • If the SDM calibration file is correct and the vehicle contains an incorrect number of loops, indentify which deployment loops are missing to make the vehicle match the SDM impact sensor calibration scan tool data list.
      • If the calibration file is incorrect
    2. Reprogram the SDM. Refer to Inflatable Restraint Sensing and Diagnostic Module Programming and Setup
    • If the number of enabled deployment loops match 
  5. Replace the K36 inflatable restraint sensing and diagnostic module.
