Yanhua Mini ACDP MSD80 Read Flash Data Error?

 Here comes the problem:

I was working on a 2008 5 series MSD80. It’s Cas3++ ISTAP. I started with reading ISN from DME using Yanhua Mini ACDP. Wired everything as prompted. Cannot read ISN, cannot read flash data.
ECU info, read no problem
Read ISN/PSW, read flash data error message
Backup flash- error too
ECU reset- no problem
Upgrade program- success
Back to Read ISN/PSW- Read Flash Data error again.
Question: what could be the problem & what is the suggestion for the next step?

Suggestions & Solutions:

Suggestions:

Some may have a similar error when paired with MSV80.0 DME. Make sure you have a good network connection.

One of our customers failed at 53% in the ISN reading process because his Hotspot speed is too unstable.

Make sure you have updated the app to the latest version.

Backup FLASH separately

If failed, do the Upgrade program, then read again.

If all the above failed, try the solutions below.

 

Solution 1:

use the on board adapter instead of wiring it with the resistors
wiring sometimes not working 100%.
These boards never fail.

Reference:

Solution 2:

Get it done on bench.
For example you can read on bench with autel im608 and gbox.

You can use gbox plus apb15 to read isn from dme, then program the key thru obd since you have the ISN from dme.
It is part of gbox2. It is db15 cable the name. no solder nothing apb15 is like the K line.

The diagram was similar to acdp only can H and can L moved took less than 10 minutes.
i.g Go to immo > bmw> 5 series > e60 cas3 > engine > next it showed read isn and it showed what you needed and how to set up
