With a 2013, follow the battery re-learn procedure in the manual. 2016-2017 needs a reset with an OBDII device or FORScan and it is also recommended to set the battery type particularly if switching to AGM as this changes Ford's charging algorithm. Battery type parameter/BMS reset is not applicable to 2011-2015 models.
2011-2015 Battery Relearn Procedure
Because your vehicle’s engine is electronically controlled by a computer, some control conditions are maintained by power from the battery. When the battery is disconnected or a new battery is installed, the engine must relearn its idle and fuel trim strategy for optimum driveability and performance. To begin this process:
1. With the vehicle at a complete stop, set the parking brake.
2. Put the gearshift lever in P (Park), turn off all accessories and start the engine.
3. Run the engine until it reaches normal operating temperature.
4. Allow the engine to idle for at least one minute.
5. Turn the A/C on and allow the engine to idle for at least one minute.
6. Drive the vehicle to complete the relearning process.
2016-2017 Battery Management System
– Battery Charging or Jump Starting:
• To charge or jump start the vehicle, connect the positive cable to the battery positive post and then connect the negative cable to a vehicle ground and not the battery negative post
• Connecting directly to the negative battery post can have an adverse effect on the Electrical Energy Management system
• If the battery is jump started or charged, the BCM must recalibrate the battery state of charge
• It takes 8 hours in sleep mode, with the vehicle undisturbed, no doors opened or keyless entry buttons pressed, and the total vehicle current draw less than 300mA, to calibrate the battery state of charge to a high accuracy
– Battery Replacement
• If the vehicle battery is replaced, it is very important to perform the BMS Reset using a diagnostic scan tool.
• If the battery monitoring system reset is not carried out, it holds the old battery parameters and time in service counter in memory and it tells the system the battery is in an aged state and may limit the Electrical Energy Management system functions
• NOTE: DO NOT reset the battery monitoring system using the diagnostic scan tool if the battery is not being replaced. This reset is reserved for new battery installation. Resetting the battery monitoring system will clear the learned battery data, the battery time in service, and will affect the aging algorithm parameters, which have been learned since the installation of the battery.
