Pinpoint Test A: BCM TPMS Pinpoint Test

WARNING: This page is about a different car, the 2016 Ford Transit Connect. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Within this test you may notice that certain test steps or actions may have been done previously in a Service Information Pinpoint Test (PPT). Please be sure to fully complete each test step presented as they are used collectively to determine the final repair recommendation. In addition, these test steps and results are recorded to assist Ford engineering teams in the analysis of IPC concerns.

This test checks the function of the BCM to determine if it has an identifiable concern. This test should only be conducted after completing basic diagnostics, applicable Service Information Pinpoint Test (PPTs) and then only if directed by the Service Information.

The BCM hardware test incorporates the following:

A process using the Professional Technician Society (PTS) website and the Integrated Diagnostic System (IDS).
The BCM on-demand self-test, other tests and steps that are used to validate the BCM functionality.
Upon completion of the test, a repair recommendation is provided which will be either; "BCM replacement is Not recommended" or "BCM replacement is recommended".
Once the test completes, a Repair Validation Code (RVC) is also generated. The RVC code is required for Ford paid repairs to claim the labor associated with completion of this test and if applicable, the labor and part for the replacement of the BCM.

The tools required to complete this test are:

Rotunda Integrated Diagnostic Software (IDS).
Vehicle communication Module (VCM) or (VCM II).
