Attachment III - Technical Information
OVERVIEWAn incorrect Body Control Module (BCM) calibration may have been programmed into the affected vehicles. This may result in degraded Air Conditioning system performance, including slow to cool and lack of cooling. Before delivering any of the vehicles involved in this program, dealers are to reprogram the BCM using IDS level 81.01 or higher.
SERVICE PROCEDURE
Important Information For Module Programming
NOTE:
When programming or reprogramming a module, use the following basic checks to ensure programming completes without errors.
^ Make sure the battery is fully charged before carrying out the programming steps and connect IDS/scan tool to a power source.
^ Inspect Vehicle Communication Module (VCM) and cables for any damage. Make sure scan tool connections are not interrupted during programming.
^ A hardwired internet connection is strongly recommended.
^ Turn off all unnecessary accessories (radio, heated/cooled seats, head lamps, interior lamps, HVAC system, etc.), close doors.
^ Disconnect/depower any aftermarket accessories (remote start, alarm, power inverter, CB radio, etc.).
^ Follow all scan tool on-screen instructions carefully.
^ Disable IDS/scan tool sleep mode, screensaver, hibernation modes.
^ Create all sessions Key On Engine Off (KOEO). Starting the vehicle before creating a session will cause errors within the programming inhale process.
Module Reprogramming
NOTE:
Reprogram appropriate vehicle modules before performing diagnostics and clear all Diagnostic Trouble Codes (DTCs) after programming. For DTCs generated after reprogramming, follow normal diagnostic service procedures.
1. Reprogram the Body Control Module (BCM), to the latest calibration using IDS release 81.01 or higher. Calibration files may also be obtained at the www.motocraft.com.
Recovering a PCM/Body Control Module (BCM) when programming has resulted in a blank module: NEVER DELETE THE ORIGINAL SESSION!
1. Obtain the original IDS that was used when the programming error occurred during Module Reprogramming (MR) or Programmable Module Installation (PMI).
2. Disconnect the VCM from the data link connector (DLC) and the IDS.
3. Reconnect the VCM to IDS and then connect to the DLC. Once reconnected, the VCM icon should appear in the corner of the IDS screen. If it does not, troubleshoot the IDS to VCM connection.
4. Locate the ORIGINAL vehicle session when programming failed. This should be the last session used in most cases. If not, use the session created on the date that the programming failed.
NOTE:
If the original session is not listed in the previous session list, click the "Recycle bin" icon at the lower right of the previous session screen. This will load any deleted sessions and allow you to look through them. Double-click the session to restore it.
5. Once the session is loaded, the failed process should resume automatically.
6. If programming does not resume automatically, proceed to the Module Programming menu and select the previously attempted process, Programmable Module Installation (PMI) or Module Reprogramming.
7. Follow all on-screen prompts/instructions.
8. Near the end of programming, the IDS will prompt you to select certain parameters. It is important to make a selection for ALL parameters listed. If the correct selection is already highlighted, you must still choose that selection before clicking the "Tick" mark to complete the configuration.
