Diagnostic Instructions Perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure. Review Strategy Based Diagnosis for an overview of the diagnostic approach. Diagnostic Procedure Instructions provides an overview of each diagnostic category. DTC Descriptors Glass Breakage Sensor 2 Signal For symptom byte information, refer to Symptom Byte List. Circuit/System Description

The glass breakage sensor will not set a DTC. On vehicles with RPO UTU or UTV, this DTC indicates a fault with the content theft deterrent sensor module. The body control module performs various communication fault detection tests to determine if a software, hardware, or communication concern exists with the ultrasonic intrusion sensor. The sensor being disconnected, a poor connection at the connector, or the vehicle battery being discharged could all cause the communication to be interrupted. This interruption stops the self test from completing which causes DTC B19F6. This is not because of the sensor failing, it is because of a previous or existing open connection between the sensor and the BCM. Restoring this connection and then arming the theft system will complete the test and allow the DTC to be cleared. Conditions for Running the DTC The ignition is OFF. The vehicle is in Park. Conditions for Setting the DTC The body control module cannot establish communications with the ultrasonic intrusion sensor. Action Taken When the DTC Sets The intrusion and inclination alarm output is disabled. Conditions for Clearing the DTC A current DTC is cleared when the conditions for setting the DTC are no longer present and the system has been armed. A history DTC will clear after 40 malfunction-free ignition cycles. Diagnostic Aids

It is important to check alarm trigger history to understand what set an alarm event. The same trigger occurring multiple times may indicate a different issue. The sensor being disconnected, a poor connection at the connector, or the vehicle battery being discharged could all cause the communication to be interrupted. This interruption stops the self test from completing which causes DTC B19F6. This is not because of the sensor failing, it is because of a previous or existing open connection between the sensor and the BCM. Restoring this connection and then arming the theft system will complete the test and allow the DTC to be cleared.
