Diagnostic Instructions
DTC Descriptors
DTC B1019 00: SDM System Configuration Error
DTC B1019 3A: SDM System Configuration Error Incorrect Component Installed
Circuit/System Description
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 V.
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 is not configured for PPS and the SDM detects that the PPS indicator is present.
Action Taken When the DTC Sets
| • | The SDM requests the instrument panel cluster (IPC) to illuminate the AIR BAG warning lamp. |
| • | The SDM disables all deployments when B1019 00 DTC is set as current. |
Conditions for Clearing the DTC
| • | The correct SDM must be installed. |
| • | The correct components must be installed. |
Diagnostic Aids
If the SDM has been recently replaced, make sure that the correct part number was installed for this vehicle. If after programming the SDM DTC B1019 00 sets as current, check for bent pins or shorting bars at the SDM connector.

Circuit/System Verification
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 unoccupying the passenger seat.
Circuit/System Testing
Note: When removing connectors inspect for damage or corrosion. Damage or corrosion in the following requires repair or replacement of the affected.
| • | PPS module wiring harness connector |
| • | SDM wiring harness connector |
B1019 00
- Ignition ON, verify the scan tool parameter End Model Part Number is correct for the vehicle.
| ⇒ | If the part number is incorrect, reprogram the SDM. |
Note:
| • | 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 |
- 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 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. |
- Connect 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.
- Verify DTC B1019 does not set.
| ⇒ | If DTC sets, replace the SDM. |
Repair Instructions
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
