Some 2003-2004 F-Super Duty and Excursion vehicles equipped with the 6.0L engine built on or before 9/29/2003 may experience a P006A or P132B Diagnostic Trouble Code (DTC) with a lack of power condition, surge, or turbocharger flutter after performing Field Service Action (FSA) 06E17, or after recalibrating the vehicle with the inferred Exhaust Pressure (EP) strategy. ACTION This procedure is to be used only on vehicles that have received the inferred EP calibration update. There are a variety of reasons why a customer could experience a lacks power condition with the inferred EP calibration. These can include causes a person may not directly see as impacting the condition or codes set. For example; a Mass Air Flow (MAF) / Manifold Air Pressure (MAP) code can be related to a MAF sensor or a MAP sensor problem. However, those codes can be caused by other items such as: intake leaks, exhaust leaks, Exhaust Gas Recirculation (EGR) problems, and aftermarket modifications. Care should be taken to follow the entire procedure outlined below. Skipping a step may lead to being unable to properly diagnose one of these other conditions setting a code. SERVICE PROCEDURE

Actuator Recalibration When replacing the HVAC control module it will be necessary to allow the HVAC control module to perform a calibration process. When installing the HVAC control module be sure to perform the following: Important: Do not adjust any controls on the HVAC control module while the HVAC control module is self-calibrating. If interrupted, improper HVAC performance will result. 1. 2. 3. 4. 5. 6. 7. Place the ignition switch to the OFF position. Disconnect the scan tool. Install the HVAC control module. Connect all previously disconnected components. Start the vehicle. Wait 40 seconds for the HVAC control module to self-calibrate. Verify that no DTCs have set as current DTCs. When replacing the HVAC actuator it will be necessary to allow the HVAC control module to perform a calibration process. When installing the HVAC actuator be sure to perform one of the following: Important: Do not adjust any controls on the HVAC control module while the HVAC control module is self-calibrating. If interrupted, improper HVAC performance will result. Preferred Method (w/ Scan Tool) Clear all DTCs. Place the ignition switch in the OFF position. Install the HVAC actuator. Connect all previously disconnected components. Start the vehicle. With the scan tool, initiate the Motor Re-calibration feature of the Heating and Air Conditioning Special Functions menu. 7. Verify that no DTCs have set as current DTCs. Important: Do not adjust any controls on the HVAC control module while the HVAC control module is self- calibrating. If interrupted, improper HVAC performance will result. 1. 2. 3. 4. 5. 6. Alternate Method (w/o Scan Tool)

To improve the transmission shift feeling during specific operating modes, the Engine Control Module (ECM) (SAE term: Powertrain Control Module/PCM) calibration has been revised. These improvements include: S Reduced downshift lag when accelerating at speeds from 10 to 20 mph. S Less gear hunting when driving on/off accelerator pedal at 20 to 30 mph (for example: during heavy rush–hour traffic). S Improved response rate during heavy acceleration from a stop. NOTE: S Version 12.2a or later Diagnostic Tester software is required to perform this procedure. S Before proceeding, verify the ECM (PCM) calibration has NOT been updated by checking for the Authorized Modifications Label (shown in step 1 of the Repair Procedure). S Harsh ATM shifting may result if any Repair Procedure steps are omitted (specifically steps 5 and 11 on page 6). Repair Procedure 1. Check for the Authorized Modifications Label affixed to the vehicle in the location shown in Figure 1. Confirm if ECM (PCM) calibration has been updated. If not the latest ECM (PCM) calibration — go to step 2. 2. Connect the Diagnostic Tester to the vehicle and select CURRENT ECU CAL from the ECU REPROGRAM MAIN MENU. Determine the vehicle’s current ECU calibration (see Figure 2). – The sample screen prints seen below are the 12.1a software version and may differ from subsequent software versions.

GENERAL INFORMATION If the HVAC control module is replaced, the Calibration Diagnostic and Cooldown tests will need to be performed. Once this group of tests have successfully passed, they can be performed individually. The engine must be running during the test to provide hot coolant for the heater, A/C compressor operation and to assure that the actuators are calibrated correctly. The HVAC control module is capable of troubleshooting the system in approximately 120 seconds . If a condition is detected, an error code is displayed. The error code cannot be erased until the condition is repaired and the diagnostic test is performed. CAUTION : Do not remove the actuators from the Heater-A/C unit assembly with power applied. Removal should only be done with the Ignition OFF. The actuators have no mechanical stops to limit the travel. If the actuator rotates and is not connected to the unit assembly, it will become out of calibration. Actuator Calibration
