Winters are very weak those years. The most recent one was quite normal - as winter should be. Plenty of snow. Yes, they are using salt on the roads but this tendency, as far as i know, is declining heavily. Snow/no snow, salt/no salt is one thing. Zero anti-corrosion protection as per design - is the second thing. After all corrosion is not only about salt. It is happening 24/7.

Hi guys! Hello, I would like to share my observations about the anti-corrosion protection of our Ford Edge cars. Or more precisely - about the factory lack of this protection. My ST just turned 4 years old. The car is very nice, I like it, there will be no newer generations, Ford doesn't give a damn about cool projects, because what's more important to them is 'diversity BS' and battery-powered Mustangs (hahahah). So, when my ST was 3 years and 9 months old, I decided to give it a proper chassis maintenance. At the beginning, it was supposed to be a thorough cleaning and basic protection (wax for closed profiles, polyutherane for visible surfaces). After washing and drying the chassis and dismantling the covers, it turned out that the Ford Motor Company had practically neglected the topic of anti-corrosion protection! This is a scandal. The joints of the sheet metal elements of the bodywork are not protected against the ingress of water and oxygen - a real invitation to corrosion! There could only be one decision: dismantling the covers, covers, rear suspension, drive, diff, shaft, exhaust, tank. Then comprehensive sandblasting of the entire chassis, application of polyurethane primer, mastic to protect the joints of sheet metal, and then rubber on the chassis and in the wheel arches. Top with hot injected waxes. At the same time, the elements of the rear suspension and the tow hook were sandblasted (rubber elements, threads, etc. protected) and covered with a special varnish. Top it all with a layer of wax. The car was in the service center for 2 months (I wasn't in a hurry). The effect is fantastic and I'm glad I decided to protect this nice car. My main message here is: shame! Shame on FoMoCo for such a scandalous approach to such an important topic as anti-corrosion protection. I can't call it anything other than intentional aging of the product. Take care of your lovely STs! I'd like to share with you a video report i was given from the guys that were doing all this work. It's in Polish - pls, use YT auto translation - it's working quite nicely. Cheers.

Story continues: analyzing wiring schematics from @Haz and comparing with Service Manual i have - built based on my Edge ST VIN. Steps to be followed as per my understanding: 1. Install light switch module ( HEADLAMP SWITCH) with one that has rear fog switch button. Already done. 2. check if wire (CLF57) connecting HEADLAMP SWITCH module, pin 2 (REAR FOG) is in place and go to BCM pin 8 (REAR FOG). What if there is no wire? To run a wire is not a problem from HEADLAMP SWITCH side. But how about BCM side? My VIN based Service Manual says BCM C2280G connector pin 8 is "not used". If there is no metal contact there then what? If it is only about putting metal pins in the connector (harness side) and crimp a wire then the question is - where to get suitable pin from? If BCM side pin is missing then... Don't tell me i have to take the whole BCM out of the car, open it and solder/whatever new connection inside:) Then another question to you guys - how the heck to take it out? Or even how to have some access to BCM? I saw BCM during installation of HEADLAMP SWITCH - it is so deep under the dash and there is zero room for hands not mentioning any manipulation around connectors! 3. Check if there is wire (SBB67) going from BATTERY JUNCTION BOX connector C1035A, pin 6, to BCM connector C2280B, pin 21: By looking at the wiring schematic it looks like this wire (SBB67) is specific for REAR FOG lamps - is it truth? But then 50 Amps fuse?! Or maybe this schematic is simplified and inside BCM this wire powers more things? At least I'm bit positive here and my VIN based Service Manual shows C2280B bin is occupied: 4. Check is there is, if not, run new wire from BCM connector C2280F, pin 25, all the way to the back of the car to connector C438 (if exist...) and to DIY lamps - do it yourself as i haven't found OEM lamps that fit in place of original reflectors in my bumper (USA ST, 2022):( Then the other wire (negative) to some ground point in the back. And here again, my VIN based Service Manual shows BCM connector C2280F, pin 25 is not used: ...so the same question on how to install it:/ 5. Adapting the whole system to make it work - will it work straight away after the connections are made or some adaptation/programming is necessary? ForScan - how, what modules, etc - but for the moment i need to win points 1-4... When i get back home i'll try to find some time and do detailed checks and make how-to story for anyone interested to follow the same path. Please put some light on the topics highlighted above. Those missing wires and empty slots in BCM worries me the most. Thanks!

bloody internet... Possible to put them here as a photos, not links to external websites?

@IWRBB - sorry mate for not answering! I have no notifications. So those pictures/info come from factory service manual i bought when i bought my car. Manual has been built based on my car's VIN. However i found more versions are covered (including 2.0 liter engine and 8F35 tranny). Yes, you're right - essential if you want to do anything around your car.

@Jetboy47 - could you share code address in ForScan you used to disable that bloody start-stop BS? I have ST 2022 and looking to get rid of SS as hell. No, i'm not going to use "elimintaor". Partially because importing it to europe will add even more $ to already ever priced gadget IMHO. Thanks!

Do I need this module? I'm using my ST in europe and i don't give a siht about all those Ford-Touch (whatever they call it) services, apps, etc.

@boostededge - are your photos still available or the links are dead? I can't see the photos. Could you consider updating your post? I have 2022 ST and I'd love to check PTU on mine this summer. Time for full fluid service in my ST:) Thanks!

I've found the following locally: KT4Z-15A-449-A The question now is the difference between KT4Z-15A-449-A and KT4Z-15A-449-B. I know 448 is for the passenger side, 449 is for driver side. But i'm not sure about the last letter - A or B. It seems version with "A" is hard to find and 99% of searches give part numbers with "B" at the end. Visually, on the photos, both looks the same.

Hi guys, i swapped from trusty Ford S-Max 2.5T (inline 5) manual transmission to 2022 Edge ST. I'm living in hilly areas and most of the time is was using my engine for braking while crusing down the hills. Noe, on Edge ST with AT i can't find the way to use engine for braking. If I use paddles to manually shift down for higher revs i still can not feel braking. Maybe a little, but nothing close to my previous MT car. Will wear brake pads and rotors within months:/

Headlamp switch is installed already though i haven't run the wires yet. When i saw the location of BCM... WTF? How to get there?! Anyway, the headlight switch I got from Aliexpress, this offer: https://www.aliexpress.com/item/1005005880630914.html and looks just fine - all the functions work properly but the one for rear fog lights due to no time to run wires. @Wubster100 - I thought this indication will come on it the digital form - icon on the LCD. I'm away from home so can't check it.

I know the thread is oldish but for others wondering how to get the AT out of the "manual mode" - press and hold the right hand side paddle (keep some 2-3 seconds) and it will blink on the dash and switch back to full auto. This is what i can see in my 2022 ST. Cheers!

I think i'll take that risk and order one to check. If i buy from Poland i can send it back easily if not ok. Will post.

Than you guys for reference. I'll change the left one as in my country rear fog lamp must be at driver's side.

I got reply from this shop: https://www.fordoriginalparts.pl/product-pol-14418-SWIATLO-PRZECIWMGIELNE-LEWE-TYL-EDGE-18-EU-_-2270321-_-KK7B-15K273-AB-_-KK7Z-15200-D.html?query_id=1 They said it will not fit 2022 ST:( And aliexpress offer is the same part number.

@Haz - MANY THANKS for explaining it in detail! The only this which is now making me uncertain is the fact that i don't have Euro-spec car. What does "AP" mean under "regional identifier"? And is ST-line share the same part number with ST? Do you still have a tool to check engineering part and service part based on VIN? Could you please check this one for me? 2FMPK4AP7NBA24289. That would be the ultimate confirmation. Thank you, Wilki

Guys, any ideas where to get rear fog light for 2022 ST from?

Guys, in my county rear fog light is obligatory. As my ST is imported from the USA i have no rear for lights. Additionally had small parking lot adventure and my left rear red reflector is gone. Do you know if any ST was equipped with rear fog light? What is the part number for 2022 ST? I can find zero information on this subject. I have schematics and replaced light switch module already. Need to run the cable and find this bloody lamp. Please shed some light. I found this: https://pl.aliexpress.com/item/1005006877583781.html Can't tell if it fits USA version as i know those lamps/reflectors installed in europe EDGE models (diesels only) don't fit in ST:(:(:( Thank you

2022 Edge ST here: the same thing - trying to identify the correct fuses for dashcam. I looked at Repair Manual for my car and fuse number 35 on BCM is "Passanger Airbag Deactivation (PAD) indicator", rated 5 amps. Fuse nember 36 says: "Passanger Door Module (PDM)", rated 30 Amps. Looks like pretty different arrangement... There is nothing about switched fuses/relays in the description.

I've just checked my 2022 Edge ST As-Built file in search for on how to disable auto start/stop function hoping your way7 will work. So on 2022 Edge ST memory cell 726-48-02 is: 6400 0364 0042. As you can see, the second digit is 4 not 1 or 0. This makes me unsure if it is safe to try to change 4 to 0 in this memory cell. Any hints? Thanks!

Sergey - have you got some detail on this installation? DaMiFo - have you got some guidelines on how to activate rear fog light functionality in BCM and IPC? In my country rear fog light is mandatory.

Guys, any update on this subject? Mine 2022 Edge ST has ice blue only and no options for color change on SYNC4:(:( And it is 2024 now, hoped they have released software update to activate this option.

Bogi here, wanted to say hello to everyone. Just bought 2022 Edge ST, imported from US. Happy to study your inputs and happy to share my findings.

Very interesting thread here. I just got my 2022 ST and am very interested in PTU related issues. So far i know PTUs on 2019+ Edges are way different to the one in previous years. I hope i will be able to look under my car in some days and provide with real photos. For the moment this what i found regarding PTUs for confused owners, like me. PTU description: The Power Transfer Unit (PTU) is a gearbox that attaches to the transmission. The PTU directs power from the transmission differential case through a dog clutch to a hypoid ring gear. A hypoid pinion gear is meshed to the ring gear and splined to the output flange. A dog clutch is used to transfer drive torque from the input shaft to the ring gear. When the dog clutch is released, no torque is transferred through the ring gear and pinion to the rear driveshaft. When the dog clutch is engaged, normal AWD function is achieved by directing torque to the rear wheels as needed to prevent or control wheel slip and improve handling There are two different models of the PTU. The low torque PTU is paired with the 8F35, 8F40, and MMT6 transmissions. The high torque PTU is paired with the 8F57 transmission. The low torque and high torque PTUs are similar in design and operation. And some drawings: Item & description: 1 - Vent tube. Unique routing for each powertrain. 2 - PTU to transmission bolt for 8F35/40 & MMT6. One-time use. 2 - PTU to transmission bolt for 8F57.

Unique parts for each powertrain. 7 - Oil temperature sensor harness bracket (If equipped). 8 - Oil temperature sensor harness bracket bolt PTU cooling system - if equipped: Item & description 1 - Fan and bracket assembly 2 - Fan and bracket assembly bolt Item & description 1 - Oil-to-Coolant cooler stud. One-time use, part of 7P159 kit. 2 - Oil-to-Coolant cooler. Part of 7P159 kit. And operating modes description: Power Transfer Unit (PTU) Operation The PTU has four (4) distinct modes of operation: Connected, Connecting, Disconnected, and Disconnecting. Each mode is commanded by the AWD module. The PTU contains a reversible DC motor and two hall effect position sensors. The motor moves the shift fork which connects or disconnects the dog clutch collar. PTU Position sensor A monitors the position of the actuator cam. PTU Position sensor B monitors the position of the shift fork. Some PTU models are equipped with an oil temperature sensor Connected Mode Connected Mode is the default mode for the PTU. The AWD module will command Connected mode at the beginning of each key cycle. In connected mode, the fork and dog clutch collar are positioned towards the RH side of the PTU. The dog clutch is engaged. The driveshaft is rotating at an overdrive ratio compared to the front axle shafts. Torque is available at the RDU. Connecting Mode To connect the PTU, the two halves of the Dog clutch must be within 40 RPM of each other. The AWD module calculates the speed differential based on transmission OSS, RDU Driveshaft Speed, and PTU gear ratio. The actuator motor will energize and rotate the gear reduction drive and the actuator cam against the actuator fork. When the dog clutch teeth line up, the cam pushes the actuator fork into position and the clutch engages. It can take approximately 100 - 150ms for the dog clutch to engage after the command is sent. Disconnected Mode The AWD module will command disconnected mode based on vehicle conditions. The purpose of the disconnected mode is to reduce drag losses from spinning the driveshaft when conditions indicate AWD will probably not be needed in the near future. In disconnected mode, the fork and dog clutch collar are positioned towards the LH or transmission side of the PTU. The dog clutch is disengaged. Disconnecting Mode To disengage the PTU, no torque can be routed through the dog clutch. That is, the RDU must be completely disengaged. Depending on vehicle conditions, the AWD module may keep the PTU engaged for the remainder of the key cycle. The actuator motor will energize and rotate the gear reduction drive and pull the actuator cam away from the actuator fork. When the dog clutch collar has moved far enough to the LH or transmission side, the dog clutch teeth disengage. Wondering if i have one on mine. Have fun guys!
