Problem:
Autel IM508 failed to read ISN from BMW F20 EDC17C50 on bench. Use 13,5V and 3A but ecu takes only 0,55A. Error “Initial communication failed”
Solution:
If failed to read EDC17C50 ISN, try
1).
I read exactly that ECU yesterday. 14.5v and 2a with im608 and gbox2. Power 608 vci or use a break out.
2).
Take the power supply for ecu from the banana pins on Gbox2 and it works
You must connect power for ecu from the banana plugs of gbox.
3). or connect like this
