Attachment III - Technical Information
OVERVIEWContamination build up on the internal electrical contacts of the engine cooling fans may cause the fans to be inoperative. Dealers are to verify the engine cooling fan operation, replace if necessary, and reprogram the PCM using IDS version 78.04 or higher. A revised cooling fan strategy will periodically cycle the fans at high speed to clean the contamination from the contacts and prevent future contamination build-up.
NOTE:
This FSA must be performed prior to performing FSA 11A02 (MyFord Touch Performance Upgrade) on affected Explorer vehicles to ensure proper cooling fan performance during the 11A02 software download procedure.
[NEW!] COOLING FAN INSPECTION
NOTE:
Maximum fan speed is required to ensure sufficient cleaning of the internal electrical contacts.
1. Using IDS, start a new session and select Data Logger. Using the Output State Control, command the Cooling Fan Speed Desired (FAN_CTRL # or FAN_DSD # - above 90%) PID to High speed for 2 minutes and verify cooling fan operation.
[NEW!] NOTE:
For Flex, MKS, MKT, Taurus equipped with a 3.5L Ecoboost engine and all Explorer vehicles, use PID "FAN_DSD".
For Flex 3.5L DOHC and MKT 3.7L vehicles, use PID "FAN_CTRL".
- Cooling fan operates properly: Proceed to "PCM Reprogramming"
- Cooling fan does not operate properly: Proceed to "Cooling Fan Replacement"
^ After the cooling fan is replaced, proceed to "PCM Reprogramming"
[NEW!] COOLING FAN REPLACEMENT
All Vehicles
1. Remove the cooling fan assembly. Refer to Workshop Manual (WSM), Section 303-03.
Explorer, Flex, and MKT Vehicles Only
2. Disconnect the cooling fan electronic module electrical connectors. See Figure 1.
3. Remove the screw and detach the cooling fan electronic module from the cooling fan. See Figure 1.
4. Install the cooling fan electronic module by inserting both bottom tabs into the new cooling fan assembly shroud pockets and install the screw.
^ Tighten the screw to 7 Nm (60 lb-in).
5. Connect the cooling fan electronic module electrical connectors.
All Vehicles
6. Install the new cooling fan assembly. Refer to WSM, section 303-03.
7. Proceed to "PCM Reprogramming".
PCM Reprogramming
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 PCM to the latest calibration using IDS release 78.04 or higher. Calibration files may also be obtained at the website.
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.
9. The last screen on the IDS may list additional steps required to complete the programming process. Make sure all applicable steps listed on the screen are followed in order.
