Reset adaptive values

[JohnB]

Battery cable trick worked on my D2 or I thought. The ECU was storing a hard fault with a dead O2 sensor that clearing the code would not turn the light off.
Touching the battery cables together for like 10 seconds cleared it.
D1 this can't be done.

I got to where I could use the cmd function to find the folder but it tells me that the COM3 is denied (though that's where the USB is plugged in).

Help? I got a used and tested MAF and plugged it in and my short term fuel % shot to 25% and the motor is shaking all over the place and running like crap.

Smoothed out after a couple restarts and a drive.

can you post a screenshot or at least the text of what is going on when you try it?

I tried to read all the post but they were so over my head not sure if I understand them correctly. If my p38 has an abnormally high idle on start-up(2,000rpm) and then drives fine after warmed up, will resetting the adaptive values possibly help fix this? I searched and found other post with similar problems and their fix was going to the shop and having the idle reset. Is this the same thing?

Couple of screenshots - I got to the command and got it to recognize the folder - but it just sits there "connecting" forever - like 20 minutes last try.

hhoward told me to keep the reader disconnected but plugged in with the window open, that's when I got it to the "connecting" screen but nothing further. I have the same OBD link he does (the one you provided previously Robert, the red one). If I try it with the link connected I get a "permission denied" result.

it needs to be plugged in to the car, the car needs to be on but not running (it may actually work while running, never tried it) and the usb plug needs to be in the laptop

each time it prints a "." it is basically pinging the car ecu with a security access request.

the "." indicates it is communicating with the usb cable, so you've got the com port right

 

[AbnMike]

Car on, not running, OBD reader plugged into the port and the laptop (at that port) but nada...I mean I can try and let it sit as long as it takes, but it was quite some time before. It only printed the one "." and no more.

Tomorrow I'll try to make a video of the procedure I use and post a link here.

 

[AbnMike]

It seems like it wants to do something, but while you guys get more than one dot. I get one dot and then nothing else.

 

[robertf]

its been 4 months since I looked at the code. had to refresh my memory

if its just printing the one then it sounds like its not talking to the scan tool, it should print one every few seconds if the scan tool is responding

here is my pc trying to talk to a nonexistant scan tool on a legit com port:

C:\Users\rf\Dropbox\GEMS>gems com1 reset

Connecting to:com1
.


here is a non existant com port

C:\Users\rf\Dropbox\GEMS>gems com13 reset

Connecting to:com13
com13: No such file or directory
.


so it sees a legit com port, but is not talking to it.
Id suspect the driver. If you have any experience with serial comm programs you can connect to the obd2 tool @ 38400 8N1 and send it an ATZ command. it should respond with "OK" if it doesn't. something is wrong. I'd uninstall and reinstall the driver

You have to remember you're talking to a point and click guy. I understand the words you wrote separately, but together not so much.

The driver to the OBD tool? It works, scans, updates, and whatnot when it's connected via my laptop. A different driver? And no, no experience whatsoever with serial comm programs.

Thanks though!

Edit: If I try to run the command with the scanner connected via the interface, it gives me a permission denied, which makes sense since the scanner is in use. But when I leave it plugged in but hit the "disconnect" button on the interface, and then run the cmd prompt, I get one dot and nada.

I'm occupied till Sunday, but I'll try to throw in some quick diagnostics and update it

 

[Injuhneer]

I finally got around to testing this and am also getting the "Permission denied" message. I am on Win 10 and made sure the cmd is admin. I'll look into it further but may go back to the Win7 laptop just for testing.

Here is a screen shot of my OBDwiz connection.

Yeah, did that months ago after the upgrade.

I guess I can try OBDWiz. I didn't need it to get the device paired and active. It behaves as if the device is denying access.

I haven't forgotten about this. I wrote this in unix and it happened to compile for windows. I know the interface sucks. I started moving it to c# so it'll be native windows with a buttons and icons and stuff requiring no command line crap. Just a bit of a relearning curve for shitty Microsoft development

No worries sir. The problem I am having is a Win 10 bit of silliness.
