launch x431

For the last two years, I have been extensively using a Launch X431 V Pro. It has worked flawlessly across car brands and models. I work mostly on BMW, which has some of the most complicated electronics. The Launch software has never failed me, including working on BMW diesel vehicles.

Over the past two years I’ve also received excellent support from the vendor, obdii365, through both their Facebook Page for customers, as well as individual one-on-one support. So when I was ready to upgrade my hardware, I was interested in sticking with Launch and obdii365's support.

With help from Obdii365 I selected the new 2022 V2.0 Launch X431 PRO3S+. Arrived in 2 days. Hardware was a huge leap forward from my prior X431 V Pro. In connecting and performing diagnostics, I would say the PRO3S+ is easily twice as fast as my prior model. The new Launch is built on the Lenovo TAB M10 TB-X605FC - a 10-inch touch screen, Android 9, and 1.8 GHz octo-core CPU account for the improved speed, visibility and useability. The PRO3S+ includes HAPTIC feedback, which is a great feature for operating the tool with tactile positive input feedback. The upgrade from the V Pro also adds 5 GHz WiFi speeds - updates easily took ½ to ⅓ the time for the prior model. The 7,000 Mah battery goes all day in the garage, without issue, in spite of increased screen size and processing speed.

There are a variety of new capabilities with the PRO3S+ (the feature set is impressive for a 3rd party product working on native brands). I’ve used the bi-directional capabilities, brake service, oil service, and several others. Simply at this price point, this really becomes the cheapest tool in the toolbox when I consider its utility against the cost.

There is no doubt in my mind that the upgrade was worth the cost. For anyone that uses their Launch tool with any frequency, it is a no brainer. For potential new Launch users, I can say that several years ago several professional mechanic friends recommended I look at the Launch as my multi-model car diagnostic tool. I am glad I took their advise!

Mercedes Benz and BMW online programming function now is available on Launch X431 Pro 5 diagnostic scanner since February 2023.  Function needs to be activated.

How to Configure Launch X431 Pro5 Online Programming?

1). Connect the computer and X431 Pro5 with a USB cable, and set the USB connection method to “Media device (MTP)” on the device

2). Go to computer and find the file named “StdCfg.ini.” in the directory  (\Lenovo TAB M10 FHDRel\Internal shared storage\cnlaunch\X431Pro5\assets).

3).Follow instruction below to unlock online programming function.

Open and edit “StdCfg.ini” with a text editor, find two fields “OnlineFlash=0” and “Flash=0”, the default value is 0, indicating that the diagnostic software does not support online programming, click the corresponding field, change the value to 1, and save. After the save value, the corresponding value will change to 1, as circled in the figure below, indicating that the diagnostic software can support the online programming function.

Find OnlineFlash and Flash
Change OnlineFlash=0 to OnlineFlash=1
Change Flash=0 to Flash=1

Note: Do not change the original number of lines, and do not change other content.

Save it after modification.

NOTE:

Online programming is restricted in Spain, Portugal and Canada. Devices in other regions can be set according to the above method for online programming.

The overseas online programming menu will not be displayed on the home page, and you need to enter the corresponding diagnostic software to have the corresponding menu.

Question 1: Someone has an adapter for reading GM ACDelco ecus with Launch X431 X-prog3?

Question 2: Launch has the wiring diagram to a part that’s not included with the xprog3.  Where can i get the adapter for xprog3 mcu3?

Question 3:  Just gone to do MB SIM4LKE ecu and diagram shows a box with k2 connection which I haven’t got. Anyone any idea?

Answer:

All functions above require a Launch MCU3 adapter.

The mcu3 adapter is not included with the xprog3/GIII programmer.

The MCU3 adapter is used to read new ECUs and TCUs as well as Mercedes Benz all keys lost.

The adapter is available in obdii365.com now.

I installed a flasher on my 2022 Macan GTS 3rd brake. The brake light would flash 2 times but then go dark and create an error message on the dash.
This is called emergency brake light. Can be activated via PIWIS or Launch X431 V+/Pros Mini coding. All rear lights flash when an acceleration (de-acceleration) parameter is met.

The default parameters are when you are doing a speed above 70mph and experience a de acceleration of 0.81G’s, the rear lights (both brake lights and 3rd light) will flash.

I activated in mine and modified parameters so that it activated at any speed above 3 km/h and de-acceleration of 0.71G’s.


For the Macan the setting is in rear end electronics.
Once you turn that option on. Set this option to 1 sec and leave everything this else as is from factory.

I also enabled emergency brake flashing on 991.1, same process as the Macan.

Problem: 

I got the X-prog3 (G III) to program keys with Launch X431 PAD VII tablet.  I run a firmware upgrade but it failed me yesterday.

Saying ‘Failed to Update the anti-theft key matching adapter firmware’. Any idea how to fix it?

Solution:

Need to send the X-prog 3 main unit back to your seller to reflash firmware.

Car model and year:

Mercedes Sprinter 316 BlueTEC, 2014, 2.2 CDI, 163 Hp

Symptom:

Mercedes Benz dealer upgraded the car ECU, now I used Launch X431 Pad VII to read and clear the trouble codes, but not able to identify the ECU. I have all the ECU Flash data, software version and hardware version, my question is can I send Launch engineer these data that I own and help me add / upgrade this car’s ECU information, if Yes, flash data or just the codes from version?

Launch Engineer replied:

Yes, we can help add / upgrade Sprinter car’s ECU information, please send us the software version and hardware version.

Look at the data supplied:

Finally! added the Sprinter ECU information successfully by the Launch engineer.

Launch X431 X-PROG3 released mega-update in IMMO Program V10.06- adding Siemens engine ecu support in the new version.

Here is a demo guide on reading, writing, backup and restoring bosch and siemens engine ecu eeprom/flash data by Launch X431 Pad (Immo Pro Pad, PAD V, PAD VII, Trottle PAD etc) and X-PROG3 (GIII).

Engine ECU example: Bosch VW MED17.5.25

Run Diagnostic App enter Immo Prog module

Connect the dongle x-prog 3 obd port or power supply as the diagram and click ok

Select Engine- Bosch- Search for ECU model-TC1782

Read the info carefully we can see we’d better use usb communication mode because an unstable signal could cause ecu damage.

ECU may be damaged due to erratic reading and writing data of Bluetooth or WiFi on bench mode. Do use USB to connect the tablet and connector.

Exit and go to Home menu, enter Setting- USB management, enable USB option

then connect device with x-prog3 by usb cable

Select ECU TC1782 and View wiring diagram

Connect ECU with X-PROG3 via bench cables

Read chip ID

Chip id reads succeed meaning well communication is built then we can start backup or restore ecu data

Backup EEPROM data

Backup Flash data

Restore EEPROM Data

Restore FLASH data

Please don’t charge the tablet when we are back up or restoring the data, and ensure the battery is not too low.

 Confirmed: Launch X431 scan tool (i.e X431 V, X431 V+ etc) allow the user to expand the storage capacity from 32GB to 128GB.

Next part is about how to use TF card to extend memory in X431 V:

Prepare:

1. Launch X431 V (for example)
2. One TF card: Over 8 gigabyte (GB), with the speed of Class 10 (which is over 10 megabyte per second).
3. One screwdriver

 

Simple procedure:

1. take off the plastic protection sleeve from its backside.

2. Remove all the screws.

3. Set aside the back cover and take out the tablet.

4. There is a TF card socket at the right side of the tablet where we insert the TF card.

5. Start up the tablet.

Open “Setting” and choose “Storage”.

Click on “SD card”, here we need to set it up first, so choose “Set up”.

Choose “Used as internal storage”;

Next is “Erase and format”, it takes a few minutes in this step;

Next is to choose “Move now”, it takes a few minutes according to the data size.

6. Job is done. Launch X431 V successfully used TF card to extend the internal storage, and the procedure is applied to X431 V+ and any other X431 tools.

Good luck!
