2010 Cadillac Truck Escalade EXT AWD V8-6.2L Page 380
Conditions for Running the DTC
Ignition voltage is between 9-16 V.
Conditions for Setting the DTC
The setup for the SDM has not been completed and the SDM does not detect the correct number of sensors or deployment loops than is expected
with this calibration.
Action Taken When the DTC Sets
* The SDM requests the instrument cluster to illuminate the AIR BAG warning indicator.
* The DTC must be cleared before running the setup SDM.
* 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.
瀚慖f another SDM DTC is set, diagnose those DTCs first. Refer to Diagnostic Trouble Code (DTC) List - Vehicle (See: Diagnostic
