DTC Descriptor
DTC B1019 00
System Configuration Error
Circuit/System Description
The inflatable restraint sensing and diagnostic module monitors the number of
safety components installed on
the vehicle. When the ignition is turned ON, the inflatable restraint sensing
and diagnostic module evaluates the
number of safety components installed and compares it to the number of
components the inflatable restraint
sensing and diagnostic module expects to see on the vehicle with its current
calibration. If there is a mismatch
between detected components and the components programmed with the inflatable
restraint sensing and
diagnostic module calibration, DTC B1019 will set. The components (if equipped)
that the inflatable restraint
sensing and diagnostic module 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 inflatable restraint sensing and diagnostic module has not
been completed and the inflatable
restraint sensing and diagnostic module does not detect the passenger presence
system (if equipped), the correct
number of sensors, or deployment loops, that is expected with this calibration.
Action Taken When the DTC Sets
- The inflatable restraint sensing and diagnostic module requests the
instrument cluster to illuminate the
AIR BAG warning indicator.
- The DTC must be cleared before running the setup inflatable restraint
sensing and diagnostic module.
- Air bag indicator will continue to flash until inflatable restraint
sensing and diagnostic module 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 inflatable restraint sensing and diagnostic module scan tool deployment
loop, impact sensor, and passenger
presence (if equipped) data will match what the inflatable restraint sensing and
diagnostic module 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, or if the passenger presence is not detected.
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
inflatable restraint sensing and
diagnostic module.
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 inflatable restraint
sensing and diagnostic module.

Circuit/System Verification
NOTE:
DTC B1019 can set after the inflatable restraint sensing and diagnostic
module
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 inflatable restraint sensing and
diagnostic module will set DTC B1019.
- Ignition ON.
- Verify no other K36 Inflatable Restraint Sensing and Diagnostic Module
DTCs are set.
- If other K36 Inflatable Restraint Sensing and Diagnostic Module DTCs
are set
Diagnose those DTCs first. Refer to Diagnostic Trouble Code (DTC) List -
Vehicle
- If no other K36 Inflatable Restraint Sensing and Diagnostic Module
DTCs are set
- Verify the enabled impact sensors identified in the scan tool data list
match the number of actual impact
sensors installed on the vehicle.
- If the number of enabled impact sensors do not match
- Verify the correct K36 Inflatable Restraint Sensing and Diagnostic
Module calibration file is
loaded in the K36 Inflatable Restraint Sensing and Diagnostic Module.
- If the K36 Inflatable Restraint Sensing and Diagnostic Module
calibration file is correct and
the vehicle contains an incorrect number of sensors, identify which sensors
are missing to
make the vehicle match the K36 Inflatable Restraint Sensing and Diagnostic
Module impact
sensor calibration scan tool data list.
- If the calibration file is incorrect
- Reprogram the K36 Inflatable Restraint Sensing and Diagnostic Module.
Refer to Inflatable
Restraint Sensing and Diagnostic Module Programming and Setup
- If the number of enabled impact sensors match
- Verify the enabled deployment loops identified in the scan tool data
list match the deployment loops
installed on the vehicle.
- If the number of enabled deployment loops do not match
- Verify the correct K36 Inflatable Restraint Sensing and Diagnostic
Module calibration file is
loaded in the K36 Inflatable Restraint Sensing and Diagnostic Module.
- If the K36 Inflatable Restraint Sensing and Diagnostic Module
calibration file is correct and
the vehicle contains an incorrect number of loops, identify which deployment
loops are
missing to make the vehicle match the K36 Inflatable Restraint Sensing and
Diagnostic
Module impact sensor calibration scan tool data list.
- If the calibration file is incorrect
- Program the K36 Inflatable Restraint Sensing and Diagnostic Module.
Refer to Inflatable
Restraint Sensing and Diagnostic Module Programming and Setup
- If the number of enabled deployment loops match
- Verify a passenger presence system is equipped on the vehicle.
- If a passenger presence system is not equipped on the vehicle
Replace the K36 Inflatable Restraint Sensing and Diagnostic Module.
- If a passenger presence system is equipped on the vehicle
- Verify the scan tool Passenger Presence System Enable Status parameter
is Enabled.
- If the Passenger Presence System Enable Status parameter is not
Enabled
Refer to Inflatable Restraint Sensing and Diagnostic Module Programming and
Setup
- If the Passenger Presence System parameter is Enabled
- Verify the scan tool Passenger Presence System Learn Status parameter is
Learned.
- If the Passenger Presence System Learn Status parameter is not
Learned
- Verify the scan tool can communicate with the passenger presence system.
- If the scan tool will not communicate with the passenger presence system,
refer to Scan Tool
Does Not Communicate with Low Speed GMLAN Device
- If the scan tool communicates
- Ignition OFF, disconnect the scan tool. It may take up to 2 min for all
vehicle systems to power
down. Ignition ON.
- Verify DTC B1019 is not set as current.
- If the DTC is set as current, refer to Inflatable Restraint Sensing and
Diagnostic Module
Programming and Setup
- If the DTC is not set as current
- All OK.
- If the Passenger Presence System Learn status is Learned
- Replace the K36 Inflatable Restraint Sensing and Diagnostic Module.
