ECUHELP KT200II user Feedback: Trying to read Mercedes ACM 2.1, getting no connection !! Checked pinout 10 times. Do you have any ideas what’s going on?
This is the ECU that this user is trying to read:
Possible reason and solution:
there are 2 different connections for acm: one is k line and another one is can, check for the correct pinout for you, as there are 2 different acm modules and both says acm 2.1.
