I want to read my dme msv90 ISN by mini acdp. I have got the MSV90 ISN reading authorization, then connect OBP+ ICP adapter with msv90 by a wiring harness, and connect to acdp basic master, then read isn using “OBD Read MSV90 DME ISN (Supports F chassis)” function, but I receive the prompt “Reading version info error”. See images attached and help me.

You don’t need to dismantle MSV90 DME, just plug ACDP device to the OBDII port of your car.
Then select “OBD Read MSV90 DME ISN (Supports F Chassis)” option to read ISN.
