I bought a USB diagnostic tool Chinese BMW Scanner for my car, 2001 BMW 330i coupe, automatic gearbox.
The software is well recognized, the drivers too.
I plug-in the diagnostic tool on the car,
then I run the program,
finally I put the key in ignition.
and when I run “Car Ident” I have these two errors: “Connection error with IDE” then “Connection error with EWS.”
BMW Scanner recognized only 2 modules (DME and EGS).
I have access to live data from DME module.
All other modules are “not found”.
I try different software version, I also try two laptops (on Windows Vista 32bit, and Windows XP SP3), same problem…
And in a forum, someone says like this:
“In E46 2002 only with OBD2 connector BMW SCANNER didn’t want to connect with modules except engine.
The solution was to disassemble device and bridge 7&8 pin.Since now it has been working flawlessly.”
Then I decided to have a try.
Here, Pin 7&8 are not bridged but pin1 & 2 bridged. So I disassemble device and bridge 7&8 pin.
Check pin assignment of OBD connector and then you will see
Another thing is that by using OBD1—>OBD2 adaptor everything works because in round connector communication lines are bridged and all is transferred to pin7 in OBD2 connector.
It works perfectly on my e46 (330ci auto gearbox) and my e39 (525tds). And I hope this post will be used to other people too, cause I didn’t find any correct solution except this.
