PPS module. The instrument panel cluster (IPC) grounds all indicator control circuits to the After the SDM is programmed, the SDM setup procedure is required. During this set up 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 B1019 3A The vehicle was configured for passenger presence system (PPS) but the SDM does not The vehicle is not configured for PPS and the SDM detects that the PPS indicator is Action Taken When the DTC Sets The SDM commands the AIR BAG warning lamp ON. 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. The PPS indicator operates as indicated in the SIR System Description and Operation.

With a scan tool, verify DTC B1370 is not set as current in the SDM. If DTC is current refer to DTC B1370. 2. If equipped with PPS, verify the appropriate PPS indicator segments illuminate by occupying and un-occupying the passenger seat. If the PPS indicator segments do not illuminate properly, refer to Passenger Presence

Circuit/System Testing B1019 00 1. Ignition ON, verify the scan tool End Model Part Number is correct for the vehicle. If the part number is incorrect, reprogram the SDM. 2. 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 If the original configuration does not match the actual vehicle equipment, reprogram 3. 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 4. Connect the harness connector at the SDM. 5. 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 IMPORTANT: When removing connectors inspect for damage or corrosion. Damage or corrosion in the following requires repair or The PPS module SDM The PPS module wiring harness connector SDM wiring harness connector IMPORTANT: If not equipped with PPS, the scan tool parameter should If equipped with PPS, the scan tool parameter should
