   • If damage is found, repair the bent pins, terminals or shorting bars as needed and perform the Setup New SDM procedure.
4. Reconnect 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 the SDM with the correct components.
6. Ignition ON, clear all PPS and SDM DTCs.
7. Operate the vehicle within the Conditions for Running. Verify DTC B1019 does not reset.
