Endless error messages from ElanScan

Postby DeanG » Fri 20.07.2007, 01:25

ElanScan has been giving me a seemingly endless series of:

No reply
No frame start byte recieved
...

Does anyone know what is going on? I did a search but didn't find any information in this forum.

Confusing, if you were getting a Bad Echo error then I would put this down to a dodgy connection or incorrect com port setup.

Sound like the request is being sent out, but for some reason the ECU is not sending a response or Elanscan does not recognise the response.

cue Alan or Geoff or someone with computer smarts to give the simple answer.

I assume you know ignition has to be on (engine can be stopped or running) for the car to reply to the program and to receive info.

Is it a USB interface or is a USB-serial in use? If so the timing of the request and response could be getting messed up. The only way around this is to use a FTDI based USB-RS232 converter and set the latency to 1ms in the advanced serial settings.

If its not that then check the wiring of the data line is ok, a good contact is made at the ALDL plug (no bent pins and the pins are in the right place). Check the interface's wire isn't damaged, too long or coiled (scraping the bottom of the barrel with that last one)
It takes 43 muscles to frown and 17 to smile, but it doesn't take any to sit on your arse with a blank look on your face.

Dean's got one of my USB interfaces and had been communicating. When did it start happening Dean? I'd check the latency timer settings - see here!

I'll give my setup a check later today. We just came home from a longish drive and the car ran well. I'll post the results of the set up later today.

Thanks.

A bit late on the post but here it goes. I checked the setup of the port and it was identical (except I am using COM3). Today I played with ElanScan a bit. I have tried starting Elanscan then the engine and the reverse. I'm still getting the error messages.

Hi all

Just bought one of these...

...getting it started on Vista was a bit of a g1t...but I seem to get readings/scan/graphs OK now... 8)

...But still getting a stream of error messages at the same time, have I done something wrong? should I be concerned?

Martin,

Have you followed the "idiots guide" I put on the 'manuals' site under 'elanscan'?

(Idiots guide is NOT meant to be derogatory - just that I have included every possible step to get to the final result)

Direct link to the instructions - https://b64c533c-a9e4-41d4-a41f-7b1948b ... 7d9af8.pdf

The downloads for the drivers are on the page referenced above, if you need them.
Dave

Just the one now, but this one's mine! - and it will be finished eventually.....

go on - click this link - you know you want to!

Dave

I didn't use your idiots guide but I completed all those steps and it still will not collect - I got the drivers from the FTDI site as per the Elan videos on youtube.

I will try your version for the drivers and see if that makes a difference

Thanks

Martin

Hey Martin,

Since it worked for you in the past, I'm assuming you double checked all these things are true too?

Has continuous 1-2 code when you use paper clip
Goes into service mode when you short out pins A & B
Has ~5V on pin G wrt pin A when you turn the ignition on
Has ~5V on pin B wrt pin A when you turn the ignition on

If they are all true, and if your experience of getting No Reply is similar to mine in the video from this old thread, then I've got bad news. I had to get a new ECU (and then it worked). You can dig into Section EMK 4 from the engine management manual to go through the trouble shooting flow charts there too, and hopefully we missed something easy, like a blown fuse, but when I had similar symptoms, it pointed to something faulty in the ECU.

Good Luck,
