FORD:
2012 Focus
This article supersedes TSBs 11-5-11 and 11-7-22 to consolidate previously released articles, update Title, Issue Statement and Service Procedure.
ISSUE
Some 2012 Focus vehicles built on or before 8/12/2011 may exhibit various automatic transmission and engine drivability concerns. The vehicle may also exhibit diagnostic trouble codes (DTC) U0422, POOD2, P068A, P0850, P2610, P2832, P286F or P2877.
ACTION
Follow the Service Procedure steps to improve the condition.
SERVICE PROCEDURE
1. Reprogram the powertrain control module (PCM) and transmission control module (TCM) to the latest calibration using IDS release 74.05 and higher or 75.01 and higher. This new calibration is not included in the VCM 2011.9 DVD. Calibration files may also be obtained at the website.
2. Perform Transmission Adaptive Learning following Workshop Manual, Section 307-01 General Procedures.
NOTE
REPROGRAMMING POWERTRAIN CONTROL MODULE (PCM) AND TRANSMISSION CONTROL MODULE (TCM) WITH LOW VEHICLE BATTERY VOLTAGE AND/OR LOW IDS BATTERY VOLTAGE MAY RESULT IN A BLANKED PCM AND/OR TCM.
NOTE
THE PCM AND TCM ARE A MATCHED SET. PROGRAMMING THE PCM WILL AUTOMATICALLY UPDATE THE TCM.
NOTE
PLEASE ADVISE THE CUSTOMER THAT THIS VEHICLE IS EQUIPPED WITH AN ADAPTIVE TRANSMISSION SHIFT STRATEGY WHICH ALLOWS THE VEHICLE'S COMPUTER TO LEARN THE TRANSMISSION'S UNIQUE PARAMETERS AND IMPROVE SHIFT QUALITY. WHEN THE ADAPTIVE STRATEGY IS RESET, THE COMPUTER WILL BEGIN A RE-LEARNING PROCESS. THIS RE-LEARNING PROCESS MAY RESULT IN FIRMER THAN NORMAL UPSHIFTS AND DOWNSHIFTS FOR SEVERAL DAYS
The Calibration Update Contains Improvement Actions And Enhancements:
^ RPM flare on deceleration coming to a stop
^ Rough idle on deceleration coming to a stop, high engine idle or idle fluctuations
^ Vehicle speed control inoperative during one drive cycle
^ Engine no-start with engine coolant temperature (ECT) open circuit faults
^ Intermittent false initialization to 21 °C (70 °F) on the instrument cluster's ambient temperature display upon engine start up
^ Intermittent no-crank/no-start condition after performing normal Powertrain Control/Emissions Diagnosis (PC/ED) pinpoint test (PPT) diagnostic procedures
^ Automatic transmission enhancements for smoother accelerations, reduced hesitation, better low speed drivability, and improved shift scheduling
WARRANTY STATUS: Eligible Under Provisions Of New Vehicle Limited Warranty Coverage And Emissions Warranty Coverage
IMPORTANT: Warranty coverage limits/policies are not altered by a TSB. Warranty coverage limits are determined by the identified causal part.
