Dear all,
What i have now are
1) carsoft 7.4 full kit
2) Com post laptop
and i was sucessfully connected to my slk230, luckily, it is now fault in the ME event. And i tried to removed the MAF plug, it show a fault too.....
Refer to some old threads, i understand carsoft7.4 can only connect to ME and some live data only. We need to use a digital 38pin connector or even a paper clip to connect to other pins "AT THE CAR SIDE" to see others system, eg. VD (varous roof) pin#21; PSE pin#20.......etc.
But i have a question here, what i should connect "at the carsoft box side"
Carsoft 7.4 and the multiplexor will read many of the R170 systems, not just ME.
On the Carsoft menu there is an option to run full diagnostic which runs through every available system in sequence. If you detect an error then you run the individual diagnostic test to get the trouble code data. The multiplexor switches the pins and no need to use any paper clips. For your model car (presume GB build) you connect to the 38 pin connector.
Plenty of picture is the very long 38 pin Carsoft thread.
Please post a picture of the equipment you have.
If you have the unit with the two buttons and the digital display then you have to select the channel manually.
The blue automatic multiplexors don't have buttons or displays, but just some LEDs.
This is what i have, i borrow it from my friend who got a W202 C230K, M111 engine too, the carsoft7.4 kit of cos made in china, with a Com port cable, black box, and comport to 38pin plug cable. it can only work in ME diagnositic only....... how can i connect to other system (eg. Varous Roof)with this kit ?
Second thought - the plugs for the 38 pin lead and the COM port seem very similar. On my multiplexor, the plug for the 38 pin (or OBd II) lead is a big 37 pin plug. It would seem you have too few leads to carry many K-lines from the various modules. Have you unscrewed the D-plug shell to see how many wires are in the plug? If only 2 or 3, then it won't work with more than 1 or 2 modules in the car.
I was sent the same unit you have and I had the exact same problems! I told the ebay seller (from Hong Kong I think) it was not a multiplexer, I returned it and the ebay seller refunded me in full. I then went and bought another multiplexer from ebay and it was the real deal... I.e. allowed me to connect to all systems, not just ME.
Hope this helps!
