Attachment III - Technical Information
OVERVIEW2005 through 2007 Freestyle, Five Hundred, and Montego vehicles may exhibit a momentary engine idle RPM surge when stopped or during low speed driving maneuvers such as in a parking lot or driveway. The idle RPM surge may be intermittent. Diagnostic trouble codes (DTCs) P0505, P0506, or P061B could be present and the Check Engine lamp may turn on. This may occur due to a buildup of deposits in the throttle body from normal Positive Crankcase Ventilation (PCV) system operation. The original Powertrain Control Module (PCM) strategy may not adequately compensate for the throttle body deposits.
If an affected vehicle exhibits a momentary engine idle RPM surge condition caused by throttle body deposits, dealers are to remove and clean the throttle body, and then reprogram the PCM using IDS version 75.03A or higher. This is a one-time repair and must be performed at no charge to the vehicle owner.
SERVICE PROCEDURE
NOTE:
Replacement of the throttle body to intake manifold gasket is not required while performing this procedure, unless the gasket is damaged.
1. Remove the throttle body. For additional information, refer to Workshop Manual (WSM), Section 303-04.
Remove and clean the throttle body to intake manifold gasket. Replace the gasket only if it is damaged.
2. Using Motorcraft(R) Choke and Linkage Cleaner or equivalent, spray the throttle body plate and bore. Using a small, soft, solvent resistant brush, clean the edges of the throttle plate and the mating sur[ace of the throttle bore to remove all engine deposit build up. Reapply choke and linkage cleaner. See Figure 1.
CAUTION:
The throttle body pivot shaft bores contain lubrication that can be compromised if cleaner is sprayed directly into shaft pivot bores.
3. Install the throttle body. For additional information, refer to WSM, Section 303-04.
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.
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.
4. Reprogram the Powertrain Control Module (PCM), to the latest calibration using IDS release 75.03A 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.
