EDIS System (4.6L Town Car): Notes

NOTE: Start all diagnostics with Quick Test procedure. See the appropriate TESTS W/CODES article. Service all codes prior to proceeding with these repair procedures unless directed here by a specific CIRCUIT TEST. These tests are dependent on results received in CIRCUIT TESTS.

NOTE: The EDIS Diagnostic Cable (Rotunda 007-00059) should be used to diagnose this system. This cable is equipped with additional circuits and components used to enhance and modify signals for testing purposes. If an aftermarket test cable is used, or diagnosis is being performed using only a DVOM, ensure technician is familiar with system wiring diagram and system operation.
