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.

Product Description

CAT Caterpillar ET Diagnostic Tool from Caterpillar provide the capability to access Electronic Control Modules (ECMs) from a personal computer. Many job-critical tasks can be performed with an electronic service tool. The user can display the status of a group of parameters (temperatures, pressures, etc.) simultaneously, view active and clear logged diagnostics, display the current configuration of an ECM and much more. The service tool works with a communication adapter to allow connection to an ECM. A graphical interface makes this software quick to learn and easy to use. A separate pull-down menu for each function enhances the “ease of use.” The version and identification of the ECM is automatically retrieved and is displayed on a summary screen when the program is started. Diagnostic tests and calibrations can also be performed.

CAT Caterpillar ET Diagnostic Tool enable service technicians to reprogram ECMs, reconfigure control system parameters, fine tune performance or diagnose the root cause of a failure the first time. These powerful tools allow service personnel to display and analyze vital performance and health information from any system quickly and accurately. The service tool communicates with any system using ATA (J1708), J1939 or the Caterpillar proprietary data link networks. The service tools provide information and features needed to help a technician diagnose problems and perform repairs and to customize and personalize the operation of a product. By allowing customers to design flexibility and configurability into a product, Caterpillar service tools stretch beyond the capabilities of preprogrammed ECMs or onboard display systems.

GM Tech2 clone works great for C5 (99) Corvette

GM Tech2 clone works great for C5 (99) Corvette: Automated Bleed, program done.

My new TECH2 device bought for £233.10
Here has a lot of folks give 5star, I believe folk’s choice.
It is in perfect working order and has the screen cover.
Also included is the TIS2000 which you will need to access the security to program keys

My Tech 2 (clone, works great) for my C5 (99) just for the Automated Bleed so I could completely flush the brake system particularly for the EBCM !!! Have since used the crap out of it, ECM/PCM re-learn, crank sensor re-learn etc !!!!

Also, use it to exercise my ABS motor every 3 months.
C5 has the built-in ability to pull vehicle specific DTC’s right in the DIC and those can be exceptionally helpful in diagnosing and correcting common C5 issues.

There are a number of functions in addition to diagnostic troubleshooting that can be accomplished with the Tech II.
and another is the ability to program out unwanted features such as F45 or F55 RPO’s ar program RPO’s into a replacement BCM.

Do recognize that the tool has extremely limited ability to change settings in either the PCM or BCM. To accomplish change you need a programming tool such as HP Tuners or EFI Live and they can change only PCM settings.

they’re very easy to use, just follow the display, and look around till you get tired, and try reading ”live data” as much as you can, it speeds up the learning curve, and try it on as many GM cars/trucks as you can too.

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
