What Do the Piwis 3 updates replace Piwis 2?
Diagnostics application is used for communication with control units. You can search for, identify, code and control program units, read out the event memory, execute complex processes, change drive links and execute routines.
Guided fault finding (GFF) generates a test plan for a fault code. This test plan shows the best sequence for carrying out tests. GFF compiles a list of recommended tests, documents and wiring diagrams
Actual values/input signals functions display you the actual values and input signals of control units
Drive links/tests function displays the drive links of control units, allows you to change the parameters of these drive links and run test routines for individual control units
Maintenance/repairs function group – use this function to call up control unit-specific processes that cannot be implemented generically from the ODX data
Coding/programming function group – use this function to write coding values. Piwis 3 can code Values automatically or set manually. This function group includes (Automatic coding, Manual
coding, Customer-specific settings, and Factory settings) coding modes
Logging – use this function to activate logging for diagnostics, guided fault finding (GFF) and measuring equipment applications. Temporary and permanent working log can be created
Filter – use this function to limit the view of the control units installed in the vehicle. In the diagnostic application, you can create, edit, activate, deactivate or assign filters
Wiring diagrams application is the representation of physical connections and layouts of circuits
Measuring equipment interface work for DC and AC voltage measurement, direct and alternating current measurement, diode testing, resistance measurement, continuity/open circuit testing, showing voltage, current and resistance over time (oscilloscope function)
The Porsche Piwis 3 Tester III can be changed from after sales mode to developer mode which allows for a lot of special features ( looking at you who want to disable start stop permanently). The software installed on a SSD, is work faster and easier to use than the previous version. For example on the diagnostic program, the tester auto detects the car model. Just plug it in, turn the key on and it does its thing. For me, I’m not sure if it is a function of the unit I have or not but the guided fault finding works well. Click on any fault and press the fault finding button and the unit tries to provide you a diagnostic plan. The plan is better and the English description is better. I haven’t tried the wiring diagram software but I imagine it works as well as the previous version. There is a new ODBC program on the unit that reads standard ODBC codes, I am wondering if this unit can be used for other cars for simple code reading. I will try it on a buddy’s car next week and let you know. There is a oscilloscope function and a multimeter function but the laptop clones don’t come with these cables. If you check out the link I added you can see a factory tool and what that kit contains as compared to a laptop clone with VCI. All in all it is a better tool but really can’t do more than the piwis tester 2 can do, only faster and on cars from model year 2018 to current which the Porsche diagnostic tool Piwis 2 can’t do.
Porsche Piwis 3 FAQs
Q: Can V39.90 Software for Porsche Piwis 3 perform all the functions of Porsche Piwis 2?
A: Yes, Porsche Piwis 3 is compatible Porsche Piwis II, for Porsche that means Porsche Piwis Tester3 includes all the functions of Piwis 2.
Q: How to update V39.90 Piwis tester III Software Future?
A: The package comes with Panasonic CF-MX3 laptop , 128G Solid Hard Disk, comes with USB dongle, can update online, if you need to update, just contact seller and send team viewer, they will update it online via team viewer for you.
Q: Can Piwis Tester II update to Porsche Piwis Tester III V39.90?
A: No, they have the different hardware, the Piwis III has the higher demand to the computer resolution.
Q: Can I use my personal computer?
A: No, the computer and the device is bound together. Because The Piwis III V38.90 is bound with the encrypted chip. If you unplug the hard disk and insert into the other computer, then the software will have no nonsense.
Q: Why need Piwis III V39.90?
A: Because Piwis II can’t work with the Porsche after the 2017 year. Only Piwis III V39.90 works with newest Porsche model after 2017 like 2018 Macan
Q: Porsche Piwis 3 programs IMMO & Key online?
A: Yes. It Support.
Q: Does Porsche Piwis 3 support Wifi?
A: Usually, the device is offline version and WIFI is disabled so that you don’t need to activate every 15 days.
Q: Can Porsche Piwis 3 connect to the internet?
A: Yes. It is allowed.
Q: As I’m researching this myself, given that you don’t have a model year that requires it, what is driving you to upgrade from piwis II, to piwis III? Is it just this: “The Porsche PIWIS 3 tester has a built in multimeter and oscilloscope and the cables are included.”, or other factors that you can note here, for reference?
A:I also have a 2018 Macan that requires the piwis3. I hope to help people in my community and I also plan to rebuild another. I’m excited my PIWIS III arrives tomorrow. I will review after I test it out. I have PSM module arriving Saturday that will need the module replacement procedure.
An interesting thing happened to me the other day. I had just received my PIWIS III and was going to use it to change out the PSM module and before I did I had it run a full diagnostic. At the time I didn’t realize that the unit was in development mode. My PIWIS 2 would only show one code, a faulty recirculation servomotor which I have struggled to physically change due to its location. When the diagnostic was complete two things happened; one I realized it was in development mode since all the responses were in German (in development mode the menus can be changed to English but the responses from the modules appear in German) And two there were more error codes. After having Google translate the German responses I discover that the b piller servomotors were mechanically jammed. It also found a fault in the brake light switch which was working properly. I switched the unit to after sales mode( the dealer mode) and those codes weren’t there Then I used the unit to monitor the servomotors in question. What I discovered was that they were indeed not moving from 0 to 100. After finally figuring out where they were located (under the front seats) I pulled one out and took it apart and the motor shaft was seized. Un seizing it didn’t do enough to fix it so I ordered 3(one for the recirc). Anyways the point is that developers mode not only tested the motors it tried to run them from stop to stop which normal mode does not. The brake light switch after checking the voltage while pressing on the switch was showing only 7 volts so it was partially shorted something else missed by the regular mode. If you have mysterious issues with no codes and have access to Porsche tester, try running it in development or engineering mode as it is sometimes called, and see if it reveals any new codes.
Q: Do you know if it is possible to activate the rear DRL and the LED Matrix headlamps with the PIWIS III?
A: activation codes are not included with the tester. You can add them if you have them but this is an online programming function and the dealer must pay Porsche for the options that he installed. When he sends a work order to Porsche he receives the activation codes then enters them into the PIWIS. Now there are some Russians who have hacked porches codes and will sell you an activation code for new options. I haven’t tried them but I did pay $125 for my original activation codes so I code reprogram a pcm and a new clock spring.
