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. |
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.

Circuit/System Testing
B1019 3A
- With a scan tool, verify DTC B1370 is not set as current in the SDM.
- If equipped with PPS, verify the appropriate PPS indicator segments illuminate by occupying and un-occupying the passenger seat.
B1019 00
- Ignition ON, verify the scan tool End Model Part Number is correct for the vehicle.
⇒ | If the part number is incorrect, reprogram the SDM. |
- Observe the scan tool PPS Options parameter to determine how the vehicle PPS is currently configured in the SDM. Verify the actual vehicle equipment and the current configuration indicated by the scan tool parameter are the same.
• | If not equipped with PPS, the scan tool parameter should display Not Present and the PPS indicator should not be present on the vehicle |
• | If equipped with PPS, the scan tool parameter should display Auto, Manual, or Auto + Man and the PPS indicator should be present on the vehicle |
⇒ | If the original configuration does not match the actual vehicle equipment, reprogram the SDM with the correct configuration. |
- Ignition OFF, disconnect the harness connectors at the SDM and verify the connector is in good condition and has no bent pins, terminals or shorting bars
⇒ | If damage is found, repair the bent pins, terminals or shorting bars as needed and perform the Setup New SDM procedure. |
- Reconnect the harness connector at the SDM
- Ignition ON, verify the scan tool System Configuration matches the actual components installed on the vehicle.
⇒ | If the System Configuration does not match the actual components installed, reprogram the SDM with the correct components. |
- Ignition ON, clear all PPS and SDM DTCs.
- Operate the vehicle within the Conditions for Running. Verify DTC B1019 does not reset.
⇒ | If DTC resets, replace the SDM. |
