ABS Module

[paunionutz]

Hey everyone,


I have a 2017 XC90 that suddenly stopped turning on—no crank or anything. When I scan the car, the ABS module (VDDM), ECM, and TCM are all missing from the network. After some digging, I found out that the VDDM acts as a CAN master, and the signal goes to that module first before reaching the ECM and TCM.

My question is: does anyone know if it’s possible to replace this module (VDDM/ABS module) with a used unit and perform a VIDA reload on it? A new one costs around $700, while a low-mileage used one is about $160.


Thanks in advance!

Look under driver seat (you have to remove it). You will find a little black box (is OBD firewall). If you have sunroof, probabily you will find that box floded. If is floded, remove it from conector, clean the conector and the car will start without it. You can open it and see of is coroded. If is not coroded, you can wash it an put it back.  After you remove the seat, remove the carpet and the black foam under the carpet. OBD firewall is part of propulsion CAN  at your car
