After changing battery in 2003 Lincoln Town Car the power driver's seat, and power mirrors not working. How can this be reset?

When changing a battery alternate power supply should be hooked up so modules an radio don't lose settings .

To get working again you would need to hook up a factory scan tool ,check codes , see if the control module for those systems can talk with the scan tool etc.... IF not , module would need to be replaced .

1. Verify the customer's concern.

1. Visually inspect for obvious signs of mechanical or electrical damage.

1. If the inspection reveals obvious concerns that can be readily identified, repair as necessary.

1. If the concern remains after the inspection, connect the diagnostic tool to the data link connector (DLC) located beneath the instrument panel and select the vehicle to be tested from the diagnostic tool menu. If the diagnostic tool does not communicate with the vehicle:
   • check that the diagnostic card is correctly installed.
   • check the connections to the vehicle.
   • check the ignition switch position.

1. Carry out the diagnostic tool data link test using the diagnostic tool. If the diagnostic tool responds with:
   • SCP+, SCP- or ISO circuit fault; all electronic control units no response/not equipped refer to Section 418-00 .
   • No response/not equipped for Driver Door Module (DDM), refer to Section 419-10 .
   • No response/not equipped for Driver Seat Module (DSM), refer to Section 419-10 .
   • If the DDM is not listed for a communication concern, turn the ignition switch to RUN, make sure all doors are closed, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs, then execute the Self-Test Diagnostics for the DDM. If the DDM exits diagnostic state during the self-test and returns to normal operation state, refer to Section 419-10 .
   • If the DSM is not listed for a communication concern, turn the ignition switch to RUN, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs, then execute the Self Test Diagnostics for the DSM. If the DSM exits the diagnostic state during the self-test and returns to a normal operating state, refer to Section 419-10 .

1. If the DDM DTCs retrieved are related to the concern, go to the Driver Door Module (DDM) Diagnostic Trouble Code (DTC) Index to continue the diagnostics.

1. If the DSM DTCs retrieved are related to the concern, go to the Driver Seat Module (DSM) Diagnostic Trouble Code (DTC) Index to continue the diagnostics.

1. If no DTCs related to the concern are retrieved, go to the Symptom Chart to continue the diagnostics.
