How to adjust the maximum sweep of your windscreen wipers using
FoCCCus.
Wiper Motor Module (WMM) calibration. The basic instructions are here:
https://www.drive2.com/l/4474628/Noting that:
When you select "WMM Calibration" (under the BCM tab) the FoCCCus progress bar will stall at 50% (appearing like FoCCCus has crashed.) Ignore that stall as it is actually waiting for you to pull down three times on the
wiper control stalk to initiate the calibration.
Once you do the three downward pulls (within 5 seconds), both
wiper arms will go to roughly 3/4 of a full sweep. Carefully move them outwards with your hands to the desired maximum wipe position. (The Ford Escape workshop manual specifies 41.5mm from the windscreen surround trim edge, measured where the arm connects to the
wiper blade. This position was too close to the
wiper top tip going off the windscreen, so I sent mine with the top tip around 10mm in from the windscreen edge. It could be because the Escape is left hand drive and has the wiper setup mirrored to the Kuga.)
IF YOU PULL THE WIPERS TOO FAR DO NOT FORCE THEM BACKWARDS- YOU WILL DAMAGE THE
WIPER MOTOR! Instead start the procedure again- do not complete the next step.
When the wipers are in the desired position, pull down on the
wiper control stalk once more to permanently store that position.
Close down FoCCCus and open
ForScan to delete all the DTC's that FoCCCus generates.
Job done.
PS: For reference, below is the text from the Ford Escape Workshop Manual instructing how to perform the above procedure using the Ford tool.

WARNING: Before beginning any service procedure in this section, refer to Safety Warnings in Section 100-00 . Failure to follow this instruction may result in serious personal injury.
NOTICE: Do not set the ignition to OFF during the procedure. Setting the ignition to OFF causes the wiper motors to accept the current windshield wiper arms position as the initialized position.
NOTE: Low battery voltage may prevent the BCM from entering Learn Mode.
NOTE: If the FCDIM displays Low Battery Audio Off or the FDIM displays Battery Saver System Off, start the vehicle and set the ignition to OFF to reset the BCM .
NOTE: Make sure the windshield is clean and dry before carrying out this procedure.
1 Ignition ON.
2 Cycle the windshield wipers on and then off. Make sure the windshield wiper arms park in the correct position.
3 Using a scan tool, place the windshield wiper motors in Learn Mode using the WMM Calibration.
4 Press the wiper and washer lever arm down 3 times within 5 seconds. The windshield wiper arms move to a preset or pre-initialization position.
5 NOTICE: If the wiper arms are pulled closer to the A-pillar than the specified distance during this step, do not attempt to move the wiper arms back toward the pre-initialization position manually. Damage to the wiper motor can occur.
NOTE: Pre-initialization can be reset by selecting INTERMITTENT on the wiper/washer switch and then selecting OFF.
Gently pull the windshield wiper blades out toward the A-pillar moulding until the distance between the wiper arm and the A-pillar moulding is 41.5 mm (1.63 in).
6 Press the wiper and washer lever arm down 1 time. This sets the current windshield wiper arm position as the approved position and the wiper arms move back to the PARK position.
7 Using the scan tool, finish the WMM Calibration by placing the windshield wiper motors in Normal Mode.
8 Carry out a low speed windshield wipe and make sure the windshield wiper motors and arms park in the correct position.
9 Carry out a high speed windshield wipe on a wet windshield and make sure the wiper blades do not contact the A-pillar.
