ISSUE
Some 2007-2010 MKZ and 2010 Fusion Sport vehicles equipped with a 3.5L engine may exhibit a rough, rolling idle, or idle speed dropping below specification. This condition typically occurs most often in hot ambient temperatures with the A/C on when idling for extended periods.
ACTION
Follow the Service Procedure steps to correct the condition.
SERVICE PROCEDURE
1. Reprogram the powertrain control module (PCM) to the latest calibration using IDS release 61.04 and higher. This new calibration is not included in the VCM 2009.5 DVD. Calibration files may also be obtained at the website.
2. Perform transmission control module (TCM) initial learning procedure. Refer to Workshop Manual Section 307-01A.
NOTE
VEHICLES EQUIPPED WITH A PCM AND TCM, REQUIRE A COORDINATED REPROGRAMMING. THIS COORDINATED REPROGRAMMING PROCEDURE MUST BE FOLLOWED EXACTLY AS OUTLINED BY THE IDS/PDS SCAN TOOL(S). FAILURE TO FOLLOW THE KEY CYCLE PROCEDURE WITHOUT WAITING FOR THE IDS PROMPTS, WILL CAUSE THE COORDINATED REPROGRAMMING TO FAIL. THE PCM WILL BE UPDATED BUT THE 1CM WILL NOT BE UPDATED AND THE NEW FILES WILL NOT BE INSTALLED. IT IS CRITICAL TO FOLLOW THE IDS/PDS PROMPTS.
NOTE
AUTHORIZATION DECAL NOT REQUIRED.
