clock reset FORD E SERIES 2015 4.G Owners Manual

Dual Batteries (If Equipped)
Your vehicle may be equipped with a frame-mounted battery located on
the passenger side frame rail, behind the front passenger door. This
battery is connected in parallel with the battery in the engine
compartment. Both batteries are used to start the vehicle.
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. Flexible fuel vehicles (FFV) must also relearn the ethanol
content of the fuel 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 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. Release the parking brake. With your foot on the brake pedal and with
the A/C on, put the vehicle in D (Drive) and allow the engine to idle for
at least one minute.
7. Drive the vehicle to complete the relearning process.
•The vehicle may need to be driven 10 miles (16 km) or more to
relearn the idle and fuel trim strategy along with the ethanol content
for flexible fuel vehicles.
•Note: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.
•For flexible fuel vehicles, if you are operating on E85, you may
experience poor starts or an inability to start the engine and
driveability problems until the fuel trim and ethanol content have been
relearned.
If the battery has been disconnected or a new battery has been installed,
the clock and radio settings must be reset once the battery is
reconnected.

3. Cycle the ignition to the on position with the engine off.
4. Turn the hazard flashers on then off three times. This must be
accomplished within 10 seconds.
If the reset mode has been entered successfully, the horn will sound
once, the system indicator will flash and the message center (if
equipped) will displayTRAIN LEFT FRONT TIRE. If this does not
occur, please try again starting at Step 2.
If after repeated attempts to enter the reset mode, the horn does not
sound, the system indicator does not flash and the message center (if
equipped) does not displayTRAIN LEFT FRONT TIRE, seek service
from your authorized dealer.
5. Train the tire pressure monitoring system sensors in the tires using
the following system reset sequence starting with the left front tire in
the following clockwise order:
•Left front (Driver’s side front tire)
•Right front (Passenger’s side front tire)
•Right rear (Passenger’s side rear tire)
•Left rear (Driver’s side rear tire)
6. Remove the valve cap from the valve stem on the left front tire;
decrease the air pressure until the horn sounds.
Note:The single horn chirp confirms that the sensor identification code
has been learned by the module for this position. If a double horn is
heard, the reset procedure was unsuccessful, and must be repeated.
7. Remove the valve cap from the valve stem on the right front tire;
decrease the air pressure until the horn sounds.
8. Remove the valve cap from the valve stem on the right rear tire;
decrease the air pressure until the horn sounds.
9. Remove the valve cap from the valve stem on the left rear tire;
decrease the air pressure until the horn sounds.
Training is complete after the horn sounds for the last tire trained
(driver’s side rear tire), the system indicator stops flashing, and the
message center (if equipped) displays:
TRAINING COMPLETE.
10. Turn the ignition off. If two short horn beeps are heard, the reset
procedure was unsuccessful and must be repeated.
