Circuit/System Verification
Verify that DTC B1015 is not set.
If the DTC is set, program the object alarm module. Refer to Object Alarm Module Programming and Setup (See: Accessories and Optional
Equipment/Collision Avoidance and Parking Assist Systems/Parking Assist Control Module/Testing and Inspection). If the DTC resets, replace the
object alarm module.
Repair Instructions
Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.
Control Module References (See: Testing and Inspection/Programming and Relearning) for Object Alarm Module replacement, setup, and
programming.

DTC B1019
Diagnostic Instructions
* Perform the Diagnostic System Check - Vehicle (See: Testing and Inspection/Initial Inspection and Diagnostic Overview/Diagnostic System
Check - Vehicle) prior to using this diagnostic procedure.
* Review Strategy Based Diagnosis (See: Testing and Inspection/Initial Inspection and Diagnostic Overview/Strategy Based Diagnosis) for an
overview of the diagnostic approach.
* Diagnostic Procedure Instructions (See: Testing and Inspection/Initial Inspection and Diagnostic Overview/Diagnostic Procedure
Instructions) provides an overview of each diagnostic category.
DTC Descriptor
DTC B1019 00
- System Configuration Error
Circuit/System Description
The inflatable restraint sensing and diagnostic module (SDM) monitors the number of safety components installed on the vehicle. When the
ignition is turned ON, the SDM evaluates the number of safety components installed and compares it to the number of components the SDM
expects to see on the vehicle with its current calibration. If there is a mismatch between detected components and the components programmed with
the SDM calibration, DTC B1019 will set. The components (if equipped) that the SDM will detect include inflatable restraint deployment loops,
impact sensors, passenger presence system components, seat position sensors, disable switches, and seat belt switches.
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.
