Piwi diagnostic program for Porche Taykan

[carlos vilarinho]

Yup,

This is where it gets complicated Carlos.

It might be that there is a wire disconnected somewhere, or that a module needs re-programmed or replaced.

At the top of the PIWIS screen, there are tabs for maintenance repairs and coding.

This is where you get PIWIS to fix things.

Also PIWIS has an option to complete a vehicle handover that will enable all things that have been disabled on the car, but there are so many things here, I would be concerned about that option.

It's hard to read the images from your phone, the glare is blocking things out.

Screenshots from your laptop would make this much easier to read.

It would also be helpful to have comments from others, not just me.

You mention the following (…..PIWIS also has an option to complete vehicle delivery, which will enable all the things that were disabled on the car, but there are so many things here that I would be concerned about that option….) just out of curiosity, what things would give you concern about that option…??

but don't you think it's possible to do as I mentioned earlier???

The coding program options in here are worth trying if you have communications with a particular module.

The problem the I see is that much of the communications are not working, so picking a place to start is not going to be easy, but getting the communications working between modules would probably solve much of the problems you have, automatic coding is the tool to use.

Which module do you think you should start with?

Which module do you think you should start with?

considering that CAN bus (Controller Area Network) is a communication system used in vehicles/machines to enable ECUs (Electronic Control Units) to communicate with each other - without a host computer. For example, the CAN bus enables quick and reliable sharing of information between your car's brakes and engine. Is there no way to identify with the piwi which modules are not receiving information……??? or is it not possible????

I am absolutely certain that there are modules in the car that continue to receive information and do not have errors and there are modules to which the information does not reach these modules and these modules are giving errors, I think it will be possible to first see module by module what the status is and then see where the information is being cut from...

I haven't been able to see the screen shots yet because of the glare.

It would help if you posted screen shots using a screen grab / scissors tool from the screen you are using.

I had no issue using the internet with PIWIS, so you should be able to drop images in here from your laptop.

Here is a bit of the hierarchy of the Taycan modules

Central Gateway (CGW)

This is the main communication hub that connects various control units and modules within the vehicle.

Porsche Communication Management (PCM)

The Porsche Communication Management system offers a variety of functions and features connecting you and your Porsche to the world around you. Some of the PCM functions include:

• Navigation: Get directions to your destination, access real-time traffic updates, or simply view a map of the area around you.
• Media: Listen to AM/FM radio, satellite radio, or connect your mobile device to listen to your favorite music or podcasts.
• Phone: Connect your mobile device to make hands-free calls and access your contacts while on the road.
• Car: Access basic vehicle functions (seat settings, lights, digital owners manual, etc.), select your driving mode, or even adjust suspension height and stiffness.
• Climate: Control the temperature and amount of airflow from each vent within the vehicle.
• Apps: If you subscribe to My Porsche through Porsche Connect, you can browse available online apps such as nearby parking, fuel prices, news, flights, weather, and more.
• Assist: If your vehicle is equipped with any driving assists, you can control and configure them via the PCM screen.
• Hybrid (If applicable ): If your vehicle is a hybrid, you can access various information such as your current driving mode, available range, and past driving statistics.
• Sound: You can completely control the balance, tone, and volume of the sound coming from the speakers in your vehicle.
• Settings: Easily access and control all vehicle and PCM settings.

I leave the fault codes here……see if you can see it better now, I put some filters on the photos, it's not 100%, but I think you can see it better...

 

[carlos vilarinho]

and now I leave the fauts codes after they were erased and this was what was left….If you can't see it, I'll have to go back to the car and do it all over again...

 

[carlos vilarinho]

note this I removed these error codes in this module: BCM Bosh AU651_018 after diagnosing my car in piwi, as you can see in the attached photos it appears this module controls the windshield wipers the wipers on my windshield do not work at the front, as well as my rain and light sensor and in piwi it shows all these errors that do not work

 

[carlos vilarinho]

Now apparently it is in this module that the windshield wipers are giving errors etc..., as I mentioned the errors above, now where is this module located in the car, will reprogramming this automatic module erase all these errors...???

I leave here something interesting that may interest and help someone else.?
