  Q: What Steps Should Be Taken Before Performing Maintenance on the Suspension Control Module on Lincoln Town Car?

  A:

  The main power system of air suspension must be cut off by toggling the air suspension switch on the LH side of the luggage compartment to stop vehicle damage and injury before starting any maintenance work. Electric modules are harmed when coming into contact with static electrical charges during exposure. The performance of essential components and systems depends heavily on suspension fasteners which become a source of costly maintenance expenses in case they fail. Installation needs new parts to use either an original equivalent part or the exact replacement part with the same number. Avoid using less-qualified replacements or substitute designs at any time. Torque specifications must be followed during parts reassembly to achieve correct retention of these components. To commence the air suspension service switch must be turned OFF before removing the battery ground cable. Disconnect the electrical power point and courtesy lamp of the lower instrument panel while removing the pushpins and extracting the panel insulator. The air suspension control module can be extracted after removing the lower instrument panel insulator by removing the retaining screws and securing these screws at 3 Nm (27 inch lbs.) when reinstalling. Disconnect all electrical connectors then pull out the rear air suspension control module from its position. The reverse steps of your removal process will finish this work.

  Q: How to service the Suspension Control Module on Lincoln Town Car?

  A:

  Vehicle owners need to upload the module configuration data to available scanning tools because this data becomes necessary for the new module post-installation. During production the new air suspension module comes factory-set with B2477 (Module Configuration Failure) DTC that automatically clears after a successful configuration process. The scan tool should erase DTC B2477 only when necessary after configuration completion. The first step involves taking out the two pin-type retainers from the instrument panel lower insulator before placing the insulator away. First remove the panel after disconnecting the footwell lamp and the power point electrical connector. Pull out the electrical connector from the air suspension module after releasing the spring clips to unattach the module from its mounting bracket. Installation of the new module requires a download from the scan tool for its configuration data before reinstallation according to removal steps.
