brewerbry, Here are the sequence of screens to get to the Thorax Airbag setting:


Let me know if you have any further questions.

Looks like you guys are Foxwell experts, so I'll share my troubles here. I've got an NT530. Used to to clear COV codes. Next morning got PDLS warning (though lights do auto-level on start), and Auto-start/stop warning. After reseting the codes they come back again on ignition. Those were non issues before i reset codes with NT530. How do i debug PDLS / auto-stop systems with NT530?

Did oil change today. NT530 doesn't like 20210227 date, wouldn't take any 2021 year date input. Anyone had any luck with it?

brewerbry

Unfortunately for us 981 owners, we do not get all of the programming menu options that the 987 does - all we get is the passenger occupancy sensor programming so no luck for us to code out the thorax airbag.

The one good piece of data is that you can determine the actual live resistance value for the thorax airbag and potentially fool the ecu by inserting a resistor of the same value - that is the route I will try. FYI my driver's thorax airbag resistance value was 2.7 ohms.

brewerbry

I am not sure - what model is your car and what is the cov code?

rubenhak

oh, apologies. I just realized I'm on 987 forum. I've got a 2013 C2S (991). Initially it was a fault with change over valves. Are you referring to the actual error code number?

Kuro Neko

Ha!
I too tried to enter 20210227 as the date I coded my steering wheel Sport and Launch Control lights, and was similarly unable to get it to accept this date.
I tried swapping the YYYYMMDD sequence to YYYYDDMM - as I know the US gets it **** backwards sometimes - and this did not work either.
So, I just accepted the default 20130203 date as prompted.
No issues (except for historical review of changes I guess).

On the plus side, engine rev limited look good, and steering wheel lights coded fine:

rubenhak

While that's ok for steering wheel, the date is quite important component for service indicator.

What is engine rev limiter? Are you guys changing the engine rev limits with this?

Kuro Neko

Agreed!


Sorry, incorrect phrasing.
I think the correct term is 'Over Rev', and indication as to the number of RPM attained within RPM range considered excessive.
An issue for manual, but less so for PDKs for obvious reasons...

rubenhak

So you guys are reprogramming to allow revving beyond red line?

Kuro Neko

No, merely to review the number of revolutions that have passed in the 'Over Rev' range in the history of the car (based on the hour meter).
I am not sure you can resent the redline this way...

rubenhak

oh, now understood

rubenhak

After updating Foxwell NT530 I got quite impressed with with it. Could enter proper oil change date. Register battery (which also clears errors with auto stop/start & PDL). Also found enormous list of tests and special functions in each of the menu. To update you would need a quite old computer with something like Windows 7 or similar running on it.

Kuro Neko

Agreed, as I've been a Chromebook user for six years now.
I suppose I could visit someone stuck in the 1990s...
Note too, the USB connector on the device dates from a similar era.

As you suggest, there is a pile of options for coding, including LED / Incandescent front indicators, and being able to turn on or off the sidelight to indicator repeaters.
It has an option for High Beam and Fog Light switch or similar, but I've not investigated what this does yet.
I cannot see any DRL entries though.

One day someone should document all the Customer-Specific Settings for each Control Module...

I explored the light options a bit - there is an option for the type of lights in the rear - blank, LED, incandescent. Mine was set to blank, I decided to change it to LED - that gave me a bulb out warning message and double-fast blink whenever I used either turnsignal, despite the 987.2 coming with LED lights. SO - I went back into the menu and selected incandescent and everything was fine again. that sort of confirms my thinking that a lot of the de-codes and reverse engineering required for these tools is coming from a single source, there are a number of reversed-function faults like this in the iCarScan X431 tool..

I also didn't see anything about running lights, but that might have been a selection done with the PCM on some cars - it is that way on my '11 Cayenne.

Would it be possible to buy the tool off Amazon and use it for a PDK service then return it? I know it's not the best thing to do, but I rather not have two OBII readers on hand (even though I could probably sell the one, not sure how soon though).
