FDIM Touchscreen Hardware Test Routine

WARNING: This page is about a different car, the 2018 Lincoln Navigator. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: This test is designed to check the function of the SYNC® 3 FDIM hardware only. It is very important that no other issues are present with systems or components that interface with the FDIM.
The FDIM hardware test helps determine whether the FDIM module hardware is functioning as designed or has an identifiable concern. As each block of tests is completed, the results are provided and directions given for the next step. At the completion of the test, a recommendation is provided where the "SYNC® 3 FDIM replacement IS NOT recommended", "SYNC® 3 FDIM replacement IS recommended" or if the concern is the result of non-warrantable damage.
Within the test routine there may be several actions or tests that may have been carried out previously in a different procedure or Pinpoint Test (PPT). However, please follow the directions provided as this test routine specifically checks the operation of the module hardware.
Through the course of this test, the diagnostic may find that an APIM replacement may be the appropriate repair. In this case the APIM Hardware Test is not required.
The tools required for this test are:

Rotunda Integrated Diagnostic Software (IDS) software
Vehicle Communication Module (VCM)

A20: THE FDIM PASSED THE HARDWARE TEST - REPLACEMENT IS NOT RECOMMENDED
NOTE: Select Log View (at the top of the information) to print a copy of the test results, if desired.

NOTE: If the concern persists, please refer to the appropriate Service Information for further diagnostics. In some cases, with additional diagnosis or assistance from Ford resources, it may be determined that even though the FDIM passed this Hardware Test, replacement is still necessary in an attempt to resolve a customer reported concern. In these cases, the FDIM Hardware Test must still be fully completed, a test validation code generated and the code included on the Ford paid claim.
- Test results: The results of the test show that the FDIM hardware test passed and that the FDIM has no identifiable issues. Replacement of the FDIM in an attempt to resolve the customer reported concern is therefore NOT recommended.
- For a Ford paid repair, obtain the FDIM Hardware Repair Validation Code by selecting the "Click for Details" button below. This validation code is required to claim the FDIM hardware test labor operation.
No fault found.

If this is a Ford paid repair ensure that the FDIM hardware test validation code is included on the claim form.
