WARNING: This page is about a different car, the 2011 Buick Regal. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
DTC B1019 can set after 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.
- Ignition ON, verify no other SDM DTC are set.
- If another SDM DTC is set, diagnose those DTCs first. Refer to Diagnostic Trouble Code (DTC) List - Vehicle
- With the scan tool observe the SDM impact sensor configuration scan tool data list. Verify the impact sensors called out in the scan tool data list match the number of actual impact sensors the vehicle is built with.
- If the number of impact sensors do not match verify the correct SDM calibration file is loaded in the SDM.
- If the SDM calibration file is correct, the vehicle contains less/more sensors than it is supposed to. Modify the vehicle to match the SDM impact sensor calibration scan tool data list.
- With the scan tool observe the SDM enabled deployment loop configuration scan tool data list. Verify the enabled deployment loops called out in the scan tool data list match the deployment loops the vehicle is built with.
- If the number of enabled deployment loops do not match verify the correct SDM calibration file is loaded in the SDM.
- If the SDM calibration file is correct, modify the vehicle to match the SDM enabled deployment loop calibration scan tool data list.
- If the SDM impacts sensor and enabled deployment loops match the vehicle build and the DTC is still current, replace the K36 SDM.
