ABS module replacement
I will be replacing my ABS module with a used one in good condition. Has anyone here done this before? Is there anything I need to know before I get started? I have the TopDon RLink J2534 to do the programming. Any help would be greatly appreciated.

ABS-moduulin vaihto käytettyyn yksikköön onnistuu yleensä, mutta tärkein asia on koodaus ja kalibrointi. Vaikka moduuli olisi “hyvässä kunnossa”, se pitää lähes aina sovittaa auton VIN-koodiin ja jarrujärjestelmän asetuksiin J2534-laitteella kuten sinun TopDon RLinkillä.
Ennen vaihtoa kannattaa varmistaa, että uusi moduuli on täysin samaa osanumeroa tai ainakin täysin yhteensopiva. Vaihdon jälkeen tarvitset usein myös ABS:n bleed-proseduurin ja mahdollisesti steering angle sensor -kalibroinnin.
Hyvä käytäntö on pitää akku vakaana ohjelmoinnin aikana, koska jännitehäiriöt voivat aiheuttaa moduulin https://roobets.fun/ brickaantumisen.

Translation:
Replacing an ABS module with a used unit is usually a success, but the most important thing is coding and calibration. Even if the module is “in good condition”, it almost always needs to be matched to the car’s VIN code and brake system settings with a J2534 device like your TopDon RLink.
Before replacing, it is worth making sure that the new module is exactly the same part number or at least fully compatible. After replacing, you will often also need to perform an ABS bleed procedure and possibly a steering angle sensor calibration.
It is a good practice to keep the battery stable during programming, as voltage disturbances can cause the module to brick.

I have used modules from multiple different years. My truck is a 2012 and I have tried units from 2010-2014 trucks. I programmed mine with Forscan by uploading the factory AS BUILT file to the new (to me) module. Here is what I have learned...
You will need a module from a similar truck - see list below.
-2009/2010 are unique in that there are no Ecoboost trucks and they use a power steering pump. If you use a module from one of these in a 2011 and later you will get other faults/errors as the later trucks have electric power steering and the 09/10 module doesn't talk to the rack (which it needs to do for error free operation). I used a module from a 2010 and it cleared my braking/ABS faults but I got a steering angle/hill descent fault because it wouldn't talk to the steering rack - I have another thread on this site talking about this issue.
- using an Ecoboost module on a 5.0 or 3.7 (naturally aspirated) truck will clear the ABS faults but will give a general braking system warning because the module will not see a signal from the vacuum pump (something the Ecoboost trucks need and ABS module checks that it is on). The naturally aspirated trucks don't have a vacuum pump.
So to summarize:
2011-2014 Ecoboost trucks need a module from an Ecoboost truck
2011-2014 5.0 and 3.7 trucks need a module from a similar truck
2009-2010 trucks need a module from a 2009 or 2010 truck, not the newer years.
