Calibration Research Tips: Ford/Lincoln Park Assist Operation Check - UPDATE
I-CAR · February 20, 2025 · Ford, Lincoln
Summary
This article clarifies that Ford and Lincoln vehicles do not require a traditional calibration for ultrasonic park assist and active park assist sensors, but instead require specific operation checks. These checks include the Azimuth System Check (using fabricated PVC pipe targets) and the Elevation System Check (using a scan tool) after procedures such as bumper cover or sensor removal and installation.
What to do on the job
Perform the required Azimuth and Elevation System Checks using fabricated PVC targets and a scan tool whenever a Ford or Lincoln bumper cover or park assist sensor is removed or replaced.
How to use it
Use this document to justify the labor and setup time required for fabricating PVC targets and performing the Azimuth and Elevation System Checks. When writing an estimate or supplement for bumper R&I or sensor replacement on Ford/Lincoln vehicles, reference these OEM-required 'General Procedures' found under the Instrumentation and Warning Systems section of the Workshop manual to prove that these post-repair operation checks are mandatory safety steps, even though they are not labeled as traditional 'calibrations'.
