Re: Unable to connect with car

Hello Kev,
tests have been done on a 2001 VW Golf 1.9L ALH diesel engine, 2002 New Beetle 1.6L AYD.
I`m sure it is a Pico software issue because Putty and other software are able to get pid`s from those ECU`s. In my logs i see that Pico does not even able to send ATZ command to interface...
Still hope we will "crack it" :D
Thank`s!

Thank you again for the feedback.

I can see at 17 seconds in the video the Baud Rate is set at 9600 using Putty and at 3:11 the Baud Rate is set at 38400 using ScanMaster.

I have checked and can confirm these baud rates are supported with NVH and so I am at a loss once again.

I will try to pursue a VAG vehicle of the era you mention but I feel I need to use your ELM 2.2 lead to keep variables to a minimum

I will add our findings to the bug report and ask the software engineers to review the video's and trace files

Onward and upwards, take care......Steve

Hello Steve, Thank`s for reply.
I want to tell you again, that this problem is not from the interface, because as I say before I try to connect with different interfaces but no positive result.
I managed to sniff the com port while Pico was communicating with ECU with some serial port monitor. Attached the logs. You can open the file with the software from here https://cdn.eltima.com/download/serial_port_monitor.exe - free trial for 14 days. Your software engineers can get something from that.

Thank you for implication! BR.

Hello!
It`s a success! :D ... but not on EDC15 VAG ECU`s ! :(
I was able to connect to a EDC16U1 VAG ECU on K-Line protocol. I think the problem is in establish comm with EDC15 ECU`s, something is different this ECU`s. Steve if you can get a VAG EDC15V ECU I am 100% sure you will encounter my problem regardless of interface type you will use. So it is not the hardware interface problem it is something with these ECU`s K-Line communication. Hope you will find the time and resources to investigate this problem and solve this. Thank You! BR

Hi VASTech,
I am in no way a VAG specialist so I do not know where to start looking for an EDC15V but happy to see what I can find for Steve. If you can give me some idea of what age and model range have them fitted I will see what I can find for him.

Kev.

Hey Kev.
EDC15 are fitted in many diesel vehicles including VAG Golf MK4, Polo, Bora, Passat from 1998-2005.
Thank You!
