Cái này cháu ko rõ có áp dụng được ko vì vụ relearn này theo manual của Powershift. Esc ko sử dụng powershift nên ko rõ quy trình có áp dụng dc ko. Cụ tham khảo thêm manual của Esc ạ.
Cảm ơn cụ!
Em copy lại phần relearn cho Escape để các cụ tiện tham khảo:
How to do a Ford throttle body relearn procedure
Ga điện tử: If you’ve replaced your Ford electronic throttle body or you’ve disconnected the battery, you must do a Ford throttle body relearn to establish a new baseline idle. Starting in early 2000’s, many car makers including Ford started installing fly by wire electronic throttle bodies. In those vehicles, the “gas” pedal isn’t connected to the throttle body by a cable. The pedal simply provides an electronic signal, telling the throttle body how much acceleration you’re requesting. A motor and gear reduction set inside the throttle body opens and closes the throttle plate to accomplish your request.

If the buildup occurs gradually, the PCM “learns” the new home position. But when your battery goes dead or you disconnect it to work on your vehicle, the PCM “forgets” the adapated home position. If you don’t do a relearn procedure, the PCM will “hunt” for a new baseline idle. It will eventually learn it on its own, but it may take over a week of driving, during which time you will experience high and low idle speeds and possibly rough idle.
FORD USER GUIDLE To begin this process:
1. With the vehicle at a complete stop, set the parking brake.
2. Put the gearshift 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.
² The vehicle may need to be driven to relearn the idle and fuel trim strategy.
² If you do not allow the engine to relearn its idle trim, the idle quality of your vehicle may be adversely affected until the idle trim is eventually relearned.
When the battery is disconnected or a new battery installed, the transmission must relearn its adaptive strategy. As a result of this, the transmission may shift firmly. This operation is considered normal and will not affect function or durability of the transmission. Over time the adaptive learning process will fully update transmission operation to its optimum shift feel.
