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.

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.
