Code C1700 Mercury Description
The parking aid system is enabled when the ignition switch is in the RUN position and REVERSE is selected.

This will be indicated by the parking aid disabled warning CHECK BACKUP AID displayed in the message center. The parking aid module is on the International Standards Organization (ISO) 9141 network and can be diagnosed with a diagnostic tool.
