2019 Cadillac Truck Escalade AWD V8-6.2L Diagnostic Instructions Page 298


* Air bag indicator will continue to flash until SDM setup procedure is complete.



Conditions for Clearing the DTC



* The condition for setting the DTC is no longer present.



* A history DTC will clear once 100 malfunction-free ignition cycles have occurred.



Diagnostic Aids



The SDM scan tool deployment loop and impact sensor data will match what the SDM has been programmed to expect to see on the vehicle. B1019



DTC will set if a deployment loop or impact sensor is added or removed from the system.



DTC B1019 will set when an open/high resistance DTC sets for a deployment loop or impact sensor. This causes mismatch between the learned and



actual components connected to the SDM.



DTC B1019 can set with no other DTCs if an unused deployment loop or impact sensor circuit is shorted to ground. This causes a mismatch between



the learned and actual components connected to the SDM.

Circuit/System Verification



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.



1. Ignition ON, verify no other SDM DTC are set.



锟斤拷 If another SDM DTC is set, diagnose those DTCs first. Refer to Diagnostic Trouble Code (DTC) List - Vehicle (See: Diagnostic Trouble



Code Descriptions/Diagnostic Trouble Code (DTC) List - Vehicle)



2. 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.



锟斤拷 If the number of impact sensors do not match verify the correct SDM calibration file is loaded in the SDM.



锟斤拷 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.



3. 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.



锟斤拷 If the number of enabled deployment loops do not match verify the correct SDM calibration file is loaded in the SDM.



锟斤拷 If the SDM calibration file is correct, modify the vehicle to match the SDM enabled deployment loop calibration scan tool data list.
