Pinpoint Test EA: BCM Exterior Lighting Functional Test (C1MCA)

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 BCM 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 Tests (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).

EA2: TEST ENTRY REQUIREMENTS
NOTE: Low vehicle battery state-of-charge can affect the BCM operation and all network communications. Battery state-of-charge can be monitored on the scan tool. A red battery icon indicates low vehicle battery state-of-charge.

NOTE: Certain vehicles are equipped with a Battery Management System (BMS) that shuts down select electrical features to preserve the battery charge. This may affect the operation of certain systems which may be noticed by the customer. If the Battery Management System (BMS) activates, it displays Low Battery Features Temporarily Turned Off in the message center. For additional information of the electrical energy management system, refer to Charging System .
- Carry out the following steps:
  - connect a battery charger and set to the appropriate charge rate based on the battery SOC.
  - apply the parking brake.
  - if equipped with an automatic transmission, place the vehicle in Park (P), or if equipped with a manual transmission, place the vehicle in Neutral (N).
  - connect the VCM I or II to the IDS desktop or laptop (do not start IDS).
