Pinpoint Tests D: BCM Interior Lighting Functional Test

WARNING: This page is about a different car, the 2019 Ford F-150. 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 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).

D2: 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 article
- 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).

D28: RESET THE BCM USING THE AS BUILT/CONFIGURATION DATA

NOTE: Completing the reset of the module using "As-Built" or "Configuration" data returns the module to the original factory configuration. All programmable parameters for this module are reset to the factory default. The status of these parameters should be noted before the completion of this reset so they can be reprogrammed into the module correctly when the test is complete.

REFER to the Module Configuration article to complete the module reset using the "As-built" or "Configuration" data.
- Start a new IDS session and identify the vehicle as normal. Do not use manual vehicle selection.
- From the Toolbox tab, select Module Programming > As-Built > BCM. Select tic to continue.
- On the VIN verification process screen, select the tic to continue.
- Select no when asked if directed here from another procedure.
- Select "Continue" to reset the module to original factory settings.
- Select "Automatic" for the as built method.
- Follow the on-screen instruction to complete the process.

Yes	No
Go to D32.	Go to D31.

D31: THE BCM PASSED THE HARDWARE TEST - REPLACEMENT IS NOT RECOMMENDED
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 BCM passed this Hardware Test, replacement is still necessary in an attempt to resolve a customer reported concern. In these cases, the BCM 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 BCM hardware test passed and that the BCM has no identifiable issues. Replacement of the BCM resolve the customer reported concern is therefore NOT recommended.
- For a Ford paid repair, obtain the BCM Hardware Repair Validation Code. This validation code is required to claim the BCM hardware test labor operation.
No fault found. If this is a Ford paid repair ensure that the BCM hardware test validation code is included on the claim form.
D32: DESCRIBE THE FAILURE

* - Indicates Mandatory Field

Please provide the symptom that led to the BCM replacement.* Enter value

Go to D33.
D33: THE BCM HARDWARE TEST FAILED - REPLACEMENT IS RECOMMENDED
- Test results: The results of the test show that the BCM failed.
- For a Ford paid repair, obtain the BCM Hardware Repair Validation Code. This validation code is required to claim the BCM (part), the BCM R & I labor and the BCM hardware test labor operations and must be included on the claim form.
INSTALL a new BCM. Order a replacement BCM and include the validation code on the form. If this is a Ford paid repair ensure that the BCM hardware test validation code is included on the claim form.
