Piwi diagnostic program for Porche Taykan

[carlos vilarinho]

Just out of curiosity but is this the way to activate piwi….????

In order to try to program the module I need piwi to be able to enter the module and so far with this piwi I cannot enter BCM 1. It seems that the module is corrupted or the module in which the error messages are most identified. I need to know what solutions I have... If it was a short somewhere with a wire, (I don't have a blown fuse) which makes things even stranger! I'm starting to think about charging the batteries and disconnecting them again, and then disassembling the entire interior of the car, from the banks to the instrument panel, panel etc… check the wiring harnesses again and remove all the plugs from the seats at the panels,dashboard….etc…, at the car been inside just with the modules and the wires and check if everything is in order…!! in my opinion and from what the errors mention it is linked to the power module... I honestly have no idea what to do now... piwi points to the BCM area but I can't use it to automatically code any module... on the other hand On the other hand, it is not possible to verify where information is passing or not and where this connection is being cut off… I don’t know what to do now…

Carlos,

On your point above:- it is not possible to verify where information is passing or not

You can investigate the other tabs, like the actual values and Maintenance Repairs to see if there is any information.

Whitex described a technique :- Try coding BCM only via CAN (0x9 option), have you tried that?

yes,?so far I have only tried to do automatic coding via can(0x9), I have also changed piwi to engineer mode…, tomorrow morning I will be in the car again and I will check the other tabs and see ,what options they give me…. I also received today a porche PPN email - support-pay-tsi-registration, I have to fill out the terms of use again because they have specific terms of use for each brand and country, that is, I will fill it out again and send it immediately…

What's the error you are seeing when trying to recode BCM1 via CAN 0x09?

 

[carlos vilarinho]

Im think this U112300 is a generic code that the OBD 11 standard identifies as Databus error value received. This error can appear in any of the control modules and it can be an initiating fault, or (more likely) it can be a consequential error (i.e. it can appear as a consequence of another initiating fault)

I sincerely believe that these errors are all connected to a single error... I don't know... maybe a broken electrical wire, or a loose pin, or some connector with oxidation (which I think is unlikely but everything is possible) all the errors here have to do with lack or no communication.

I am trying to ascertain whether PIWIS has a problem communicating with BCM1, or is this a coding write error, i.e. BCM1 is write protected.

I don't think Bcm 1 is write protected...

I spent all day today seems 10 oclock in the morning at 3 oclock in the afternoon today trying to enter the BCM1 module and try the automatic encoding and the piwi always gives me the same error, after giving the error I try to enter to read the piwi date online

As I was unable to automatically program the module, I ended up giving up trying... at least I managed to locate where some modules are located in the car... one of them is the BCM1 * I'll leave photos)

It seems your piwis may not be fully offline functional. Does it let you manually code individual values in BCM1 (kodierwert option)?

I am having difficulties with automatic programming of the BCM1 module. So that you can better understand the problem, I will record a video that will show the entire process up until the moment the program stops advancing.

Please review the video and let me know what may be causing this situation, as the photos of the error I posted yesterday do not appear to be explicit about the problem! If it is necessary to correct any step or detail in the execution, I am available to make the adjustments.

Thank you for your attention and support.?

As promised yesterday, I'm publishing a video here so you can see what the problem is with my piwi, or if it's actually me who's doing something wrong, entering the PCM as a guest in private mode and the car key in the second position. vertical, the piwi that I have, as you can see, only allows me to diagnose errors and nothing more... if I see the need, I will uninstall piwi and install it again... I try to perform automatic coding or other functions that do not give errors and it is not possible...

You don't need to create the VAL every time (actually you never need to create it). First, it takes forever, and second, I've had issues in the past where the tool just hangs. It also can run out of space (it has some internal limit how much it can store before it requires you to save it to a file, if you never saved, it's probably full by now). Just say NO at 6:00 in your video.

During coding the issue seems to be the PIWIS cannot talk to the rain sensor, which is why it's trying to connect to the internet to find out what sensor your car is supposed to have. If I was go guess, there is a wiring issue somewhere, or one of the ECUs is broken and unable to talk through some buses. I don't think you'll be able to code your way out of it. I would start locating and checking the wiring. The "electrical faults" on the LIN buses mean something might be disconnected or shorted out. These are just my guesses. Unfortunately this is not an exact science. Efforts like this are always exploration, trial and error.

Thanks whitex, so the best thing to do is to disassemble the entire interior of the car in search of a broken or unconnected wire and check all the module plugs one by one... How do I know if one of the ECUs has broken…????Or remove all the interior plastics, table seats, carpet of the car etc… etc… Because through the piei we will know what the problem is exactly… correct… what would be your option… what to do next from now on???
