Scania - Knorr EBS module
Hello to all. I've got this Scania PB bus with a bad EBS control module. I've disassembled and found a capacitor to be in shortcut and burned a small portion of the board. I dont have any idea what capacitor value might be. Any suggestions?
Also I dont know if there were other components missing in that spot...

let me know what is the issue!,

for repairing  any ECU first we should know external wiring diagram. So we know the function every pin.
For example we know power supply B+, 15 On and - . From there we check the connection to internal diagram of ECU. I guess the first think you should find why the capacitor burn, may be there is some short circuit . For the value let us find later.

if any question let me know. Do not hesitate to ask me. I will help as much as I can. just for your info I usually work on Actros ECU, like GM,FM,HM etc
