It works on the C4. I assume the reason is that it has the drive by wire on the 99 C4 vs. throttle cable.

I tired mine again with a very high end custom laptop and it still didn't work. It will do the engine codes but won't hook up to anything else.

DPorto, I mentioned earlier but in case you missed it, my '99, also a C4 with e-gas, works as expected on a Windows XP Parallels VM on my Macbook Air.

Sorry to hear yours isn't working right. I'm surprised they won't replace just as a good customer support move. Mine works but often gets confused if I cycle the key while the app is running. Also, I don't think they say it in the instructions but using a usb extension cord is a big fail (just doesn't work right).

I've found I get the best customer support when I voice my problem on there Twitter feed. No company wants that kind of exposure. Good luck. Keep us posted, we're listening

Will it clear codes and show current values?

I have the durametric pro-version and have a 1999 C2 (march build date) ROW specs and RHD. I was able to clear a fault code in the airbag system that I caused when removing the inner doortrim with side airbag and accidentaly switched the ignition on. I have just double checked and can confirm that my durametric talks to the airbag system. Maybe I'm very lucky?

FWIW, I have a 99' cable wire, my enthusiast edition worked for the airbag light. I was using an old laptop running win 7, I tried my 2in1 with 10 last year and it did not work.

Durametric working with 7 and not 10 happened with both the 996 and ctt.

Ya, I was just going to confirm that I can clear codes and get values on my '99 C2 (3/98 build date)as well. Haven't tried the airbag yet but all else seems to work fine.

On the engine management system only, it won't connect to anything else

Hi guys,

Regarding the first question of this thread, did you found a solution?

Here my issue:
No communication possible with my air-bag module (My mechanic was not able too, with pro cables...)
Air-bag light always ON
Can't lock the door.
And I have battery voltage on pin 3 of the ODB connector (between 3 and 4 and 3 and 5), when ignition ON.

My car is a Boxster 1998.

I disconnected the non-OEM auto radio... but same.
I replaced the SRS (air bag module), same issue.

Anyone could help me to find how to troubleshoot my voltage on Pin 3? or confirm that is not normal on 986? And I am on the right path to solve this air-bag light issue...

Thank you.

You may have to try the dealers. I've seen cases where the cars were not the problem and the dealers were able to read and reset the codes without problems.

Thank you Ahsai.

Currently the Porsche dealer is not close to my home.
And I need to go through the safety check first... to be "legal"... no license plate yet...

It is the reason why I am trying to do it by myself... And, I want to understand too... :-)

According my reading, my best chance is to validate if my auto-radio was the cause, is to use a short circuit detector on the ODB 2 (a VAG-Saver like tester) or use the 1k Ohm method...
This should tell me is I really have a short-circuit (with or with-out the auto-radio).

But I agree that to clear the airbag code I will not be able to do it, without pro cable... or at the dealers.
btw my cheap PIWI cable stop working some weeks ago... perhaps because of this issue... another one is on the way, but if I have still this voltage/short-circuit, I want to be sure before try again and destroy another cable...
My other standard ODB2 reader still works (but can't read air-bag module as expected, then I guess, this one is not trying to read K2 line...)

Any comments are appreciate Ahsai or anyone!

Thank you.

The airbag is on the second K-line, which is connected to pin 3 of the OBDII port. K-line idles high (bit "1"). When the scanner wants to send a bit "0", it pulls the K-line to ground using an unprotected transistor. If the K-line is shorted to +12v, that will kill the transistor when the scanner tries to pull that 12v to ground.

To test if pin 3 is shorted to the +12v, connect a ~500ohm resistor between pin 3 and +12v, then another 50ohm (5w or hgher) resistor between pin 3 and the ground. Now measure pin 3. If it only has ~1v, your K-line is fine. If it's still at 12v, the K-line is shorted to 12v. Be careful the 50ohm resistor will get hot if the K-lime is shorted to 12v.

Thank you Ahsai for this very precise answer.

I will try to test that asap.

I will post my findings!

Have a great week end!
