How to solve Cummins INSITE 8.2 Connection Error 5204 5202 5201 5200

With DPA5 adapter,I try to connect with Cummins insite and i have error code 5204 or only no connection and not blinking the leds


This is the error 5204 popped up when connect Prostar 2005 with cummins engine:

ECM connection

Error number: 5204

Please check the following conditions:

The cables are between the data link and the ECM are properly connected

The cables are in good condition

The correct adapter type is selected

The correct communication protocol is selected

Select retry, cancel or help for additional troubleshooting steps



Here is what have been tried but failed!

Try to connect whit J1939…..same issue

On truck does not even get the engine and the others only couple line and very slow, might be some thing with them trucks

Some things odd2006 models connect through J1939 and works.
Tried on 3 trucks already that are 2005 and older the connect thought J1708 it says engine 128
And when doing the J 1939 test on them it says something like data error

Check the driver is installed well

J1939 & J1708 are added to the software

Finally, SOLVED!

The solution is this, connect, then scan to diagnostic connector but not to USB, open the Cummins insite and push connect, when the Insite begin to connect, immediately connect the USB and ready….

The final tip- Error Messages for communication failures:

If the “Auto Configure” and/or “Data link Adapter Connection Test” do not find the adapter when connected, manually configure the Cummins INSITE 6 Data link adapter connection.
