How does piwis3 work?

Piwis 3 V38.050.030 Porsche coverage:

Works with Porsche 2002-2019 year with Doip diagnosis

Porsche 911(997) (991)
Boxster/Cayman (987)
Cayenne up to MY 2010
Cayenne from MY 2011

Especially the latest models:
Paramera (971) 2018
Caynenne (92A) 2018
Macan (95B) 2018
911 (991) 2018
and other old models

Piwis III V38.050.030 Language:

piwis 2 or piwis 3?

PIWIS3 can communicate with newer cars/modules which use the DoIP protocol – PIWIS2 can’t. PIWIS3 is best if you want to future-proof yourself, but PIWIS2 will work with Porsches up to and including MY2017 (IIRC), so maybe that’s enough for you, but PIWIS3 will have the most up to data and flash files, etc. PIWIS III is much faster comparing to PIWIS II.

MDI 2 Features

Data Link Connector Cable

TheData Link Connector Cable is the external test equipment(ETE) cable that connectsthe  GM MDI2 to the vehicle’s SAEJ1962Data Link Connector (DLC).The DLC Cable with the grey SAE 1962 connector is specifically designed for the MDI 2 and measures 1.8 meters in length.

Power Source

The MDI 2 is intended to be powered from the vehicle battery via the DLC Cablefor normal use. If the MDI 2 does not have sufficient power (12V) to perform vehicle diagnostics, the MDI 2 will inform you of insufficient power for diagnostics by blinking the Vehicle LED in the color Red.  This scenario can be seen when the MDI 2 is only powered from the 5V USB connection to the PC.  If 12V power is lost or not detected while the MDI 2 is communicating with the GDS2 or Tech2Win application, the MDI 2 speaker will also beep to inform you of the loss of power.  Beeping may occur if the DLC is accidently dislodged.

The MDI 2 may be powered over USB only to perform firmware updates fromyour PC. 12V powercan be supplied by the vehicle DLC or the DLC Cable Self Test Adapter.

Some IMPORTANT information about powering your MDI 2:?
12V is required for Vehicle Communication?
12V is required for Wireless Configuration and use?
12V is required for use of the Self Test Adapter?
5V or 12V required for MDI 2 firmware Update or Recovery

Note: The DLCCableSelf Test Adapter cannot be used for vehicle diagnostics.LED IndicatorsSevenLight Emitting Diodes (LEDs)are located on the front of the Automotive Scan Tool MDI 2. The LED indicators provide the following status information


What does the CANdi module do

CANdi adapter user manual for  GM Tech 2 clone scanner:

What’s the candi module?

What is the real purpose of the candi module?

What is the CANdi module used for?

What’s the physical interface and LED?

“NO CANDI Communication Established”

What’s the candi module?

An industry change in protocol from OBD II to Controller Area Network (CAN) is ongoing. In order to perform diagnostics on a vehicle that uses the CAN interface, you will need the Tech 2 and a CAN diagnostic interface module. The CANdi module connects between the Tech 2’s diagnostic link cable and the OBD adapter.



The Controller Area Network Diagnostic Interface (CANdi) is an in-cable module that works with the existing Tech 2 components including the VCI, cables and adapters. Installed, the CANdi module is fully backward compatible with current tester functionality. The module powers up in a way that makes it transparent to the user.

That is, unless the Tech 2 enables features specific to the CANdi module. This allows the existing Tech 2 software to be used with no changes, whether or not the CANdi module is installed.

What is the real purpose of the candi module?

The CANDI module reads the CAN Network on cars that have it. Corvettes 2005 and newer use the CAN Network. Still use a OBDII connector but the Candi module is needed to read the data on the CAN Network.

What is the CANdi module used for?

The primary function of the CANdi module is to add CAN capability to the Tech 2 scan tool.

The CANdi module:

– support simultaneous communications on three CAN buses

– provides high speed UART communications with Tech 2


What’s the physical interface and LED?

CANdi adapter connects the Tech II by way of the existing Data Link Connector (DLC) Burndy Connector. The vehicle side connection remains unchanged using the existing adapter to interface between the Burndy connector and the SAE J1962 connector. When functioning properly, CANdi’s LED flashes. In the vent of a problem,the LED will be constantly illuminated.



How will you do with “NO CANDI Communication Established”?

How-to’s of CANDI module communication errors:

“CANdi module was not detected for Tech2”


“NO CANDI Communication Established”

First, please make sure you plugged the candi adapter in to the car and the tech 2 before powering up

Then, disconnect the connector leaving the candi adapter going to the OBD port. Plug it back in and make sure its real snug, then plug it into the obd port. I need to do this every now and then with my clone one. Usually it works after. Suspect the pins arent making the best contact.

Tech support from professionals:
*   With the car ignition off, connect the GM Tech2 and CANdi module (which is now one long cable).
*   Power up the Tech
*    You’ll get 12V from the DLC (now it takes me a half hour to find the “DLC means” Data Link Connector “and is what we also call the OBD2 connector, so be prepared to be stumped by TLA’s (Three Letter Acronyms)
*   At the main menu press F3-tool options
*   At the tool options screen select F9, CANdi Diagnostics
*   There are two tests on the next screen, run them both. The CANDI should talk to your 2004+ car
*   Either turn the ignition key of the car, or start it (for a C6 there is not an “on”).
*    Press the EXIT button until the Tech 2 goes back to the main menu.
*   Select F0, Diagnostics.
*   Make sure you want to look at the module. You may be choosing body style; You may need the body code (sometimes the third character in the VIN) You may also be asked about certain options, like ZL6. They are on a tag in the glovebox.
*   After that you will be able to play with the Tech2 clone.

IMPORTANT: Sometimes, it’s just problem with candi, as when using on other cars without candi, it’s just perfect. So you should have a good candi such as . It’s just better, but still needs to connect a few times. So I you can buy another card 148. If not totally solved, rewrite the card to 143 and 136. Both work fine. That is, 148 is no good for candi. Could be corrupted software, or the card problem. These cards coming together with Tech 2 are not good sometimes. You’d better but china knock-offs from a man of his word to trust in. Here, is one of them you can go with.

Review 2: successfully test 2004 XJR

The one I bought came with SDD V143. I had previously understood that V131.03 was the latest version that could be used without an active subscription to TOPix, so I purchased that version of the software separately. But after additional research, I installed the V134 software and it’s working just fine with WiFi turned off (otherwise it wants to try to log on and update itself). The seller stated that V134 only worked with 2005 vehicles and later, but it’s working fine with our 2004 XJR.


Review 3: successfully test 04 X350

When I bought mine, the JLR Mangoose SDD software bundled with the cable was V134, but I had been led to believe that the latest version of SDD that would work without an active TOPix subscription was V131.03, so I purchased that separately from an eBay seller based in the U.K. I later learned that V134 works fine with our ’04 X350 as long as I disconnect the computer from the Internet and reset the computer’s date to August 01, 2012 before I start the SDD program, which I’m running in a Windows XP Pro virtual machine on a Windows 7 laptop. I once let the clock creep up to November 2012 and the software functionality was disabled because “It had been too long since the software was updated.” Resetting the clock to August 2012 restored the functionality.

Review 4: successfully test 2004 XJ8

The software does run in XP mode. And contrary to the seller’s claim that it works only with cars 2005 and newer, it does work with my 2004 XJ8.

While, another user’s test result is: Thus far I can’t get SDD V138 to work with my 04 XJ8, but I’m using a different laptop and my Windows 7 64-bit running a 32-bit XP SP2 VM doesn’t want to take the Mongoose drivers.

To confirm whether JLR Mangoose really work with 04 year Jaguar, I consult in the engineer from JLR factory. He said it is true that a part of users successfully test SDD on some Jaguar from 03 to 04 year, but meanwhile some users fail to test on the same car, take the above 2004 XJ8 for example, one user successfully test, another one fail to test. Therefore, if anyone who want to use JLR Mangoose to test Jaguar before 2005year, you can have a try.

Part 4: JLR Mangoose SDD VS JLR DoiP VCI

1). JLR DoIP VCI works with new models:

Porsche PIWIS II 2 Perform a Forced PDK Update for Porsche

This article show a step-by-step guide on how to use Porsche Piwis Tester 2 to force PDK update for Porsche.


Porsche PIWIS 2 V18.15 V17.500 Free Download

A forced PDK update is required when a vehicle possesses the Q033 ROM and an open campaign update is not visible via the PIWIS tool. This procedure will update the PDK to a Q061 or newer ROM. This update is required to run the latest PDK OTS maps with custom features such as faster shift speeds, sequential shifter stalk, dual paddle to neutral, no kickdown, and no creep. These features would otherwise not be possible running the Q033 ROM.

Applicable Model/Year

2013-2016 Porsche 981 Cayman and Boxster (Base, S, GTS) w/ PDK Transmission

2012-2016 Porsche 911.1 NA Carrera (Base, S, GTS) w/ PDK Transmission

2014-2016 Porsche 911 Turbo and Turbo S w/ PDK Transmission

Note: The update process does take some time (30 to 45 minutes), so it is important to have a battery charger (10A to 12A recommended, or a charger with a “flash” setting will work) on the car’s battery during this process. It would also be a good idea to keep a charger on the PIWIS II computer as well.


Porsche PIWIS 2 Forced PDK Update Procedures:

1.Connect a battery charger to the car’s battery, put the key in the “ON” position (engine off), and turn on the PIWIS II tool. The Car Diagnostic Tool PIWIS II will need to be connected to the OBD II port at his point as well.
2.At the main menu on the PIWIS II, select DIAGNOSTICS >> 911 >>> 991. Your selection may vary if you have a Boxster/Cayman.

Porsche-PIWIS-II-2-Perform-a-Forced-PDK-Update-for-Porsche-2 Porsche-PIWIS-II-2-Perform-a-Forced-PDK-Update-for-Porsche-3

3.At this point, the PIWIS II will load up the software and prompt you to a new menu.


4.Select the “Transmission Control” unit control. After this is selected, scroll to the right on the top overview bar and select “Programming”.
You can now select “Automatic Programming” and hit the “Next” button on the bottom right of PIWIS II.


5.From here, Unit Documentation and the update will begin, several prompts regarding battery charger use and ignition on will appear. Continue to press the “Next” button on the bottom right to move forward with the process. You can keep an eye on the progress bar on the bottom and Steps listed at the top. Keep an eye on the PIWIS II for any ignition off sequences or need to press the “Next” button.

7.And that’s it, you’re done! This would be a good time to check for any transmission fault codes and clear them if they are present. You can confirm you are on the latest Q061 ROM by selecting the “Transmission Control” function on the main menu and selecting “Extended Identifications” on the top scroller bar.
