Problem:
One of our customers downloaded Xentry XDOS 2025.03 from mhhauto forum.
He was using a VXDIAG VCX Plus with Mercedes License C6 on latest firmware (VCI 1.9.6.0, DoIP 1.9.2) and drivers (3.2.6.240827, VCI version 202409).
When starting XENTRY Diagnosis Cars AKT (rapid short test) everything works perfectly well, VIN gets identified and short test is performed.
When starting XENTRY Diagnosis Cars and trying to connect the Multiplexer to the car, he gets an error during Step 1 out of 6.
“Initialization of the Multiplexer has failed.
Possible causes and remedie:
– The connection between the multiplexer and the diagnostic socket has an open circuit.
– The link between the diagnostic unit and the multiplexer is interrupted. The power supply at the diagnostic socket (circuit 30 and (or) circuit 31) is faulty.”
VCX has a stable connection to the computer.
How to fix it?
Here is the clue:
VXDIAG VCX is compatible with 2025.03 xentry xdos.
For the Xentry software provided by VXDIAG:
This is a common communication issue, which may be caused by C6 driver or hardware.
In this case, VCX Plus has a stable connection to laptop which means the hardware has no problem. The driver might be the problem.
Make sure you have installed the C6 driver in vx manager and keep it up-to-date.
For 3rd-party xentry software:
The cause is unknown. This is the customer’s feedback.
“I reset my windows and whole system and reinstalled XDOS 2025.03 using the new Fullfix of Samik 4.8.4 and now everything works as intended.
If someone else is experiencing that issue maybe the best is to reinstall the whole system instead of wasting time in error handling.”
We recommend using the xentry software from VXDIAG.
