DTC Descriptors
DTC B1019 00: System Configuration Error
DTC B1019 3A: Incorrect Component Installed
Circuit/System Description
The passenger air bag ON/OFF indicators are used to
notify the driver when the Passenger Presence System
(PPS) has enabled or disabled the I/P inflator module.
When the ignition is turned ON, the ignition voltage is
supplied to the passenger air bag ON/OFF indicators
and to the PPS module. The instrument panel cluster
(IPC) grounds all indicator control circuits to the
passenger air bag ON/OFF indicators for illumination.
The IPC receives serial data messages from the
supplemental inflatable restraints system to turn ON the
indicators as necessary.
After the SDM is programmed, the SDM setup procedure
is required. During this set up procedure, the SDM will
compare the content that was just programmed to the
actual components that are installed on the vehicle. If
the SDM detects that there are too few or too many
components on the system, DTC B1019 00 will set and
not allow the setup procedure to complete.
Conditions for Running the DTC
Ignition voltage is between 9-16 volts.
Conditions for Setting the DTC
B1019 00
• The SDM was programmed with the wrong options for
the vehicle.
• The wrong components were installed for the content
of the vehicle.
• SDM connector may have bent pins or shorting bars
causing the SDM to learn deployment loops that are
not actually present.
B1019 3A
• The vehicle was configured for passenger presence
system (PPS) but the SDM does not detect that the
PPS indicator is present due to loss of power at
indicator.
• The vehicle is not configured for PPS and the SDM
detects that the PPS indicator is present.
Action Taken When the DTC Sets
• The SDM commands ON the AIR BAG warning lamp
via serial data communications.
• The SDM disables all deployments when B1019 00
DTC is set current, not for B1019 3A.
Conditions for Clearing the DTC
• The correct SDM must be installed.
• The correct components must be installed.
• The PPS indicator operates as indicated in the "SIR
System Description and Operation".
Diagnostic Aids
If the SDM has been replaced, make sure that the
correct part number was installed for this vehicle. If after
programming the SDM and the B1019 00 sets current,
check for bent pins or shorting bars at the SDM
connector.
