VCI module (SmartLink C V2.0)
The SmartLink C V2.0 device features powerful functions and it can be applied in the following situations:
1). When as a VCI (Vehicle Communication Interface), it needs to work in conjunction with the Diagnose module of the tablet, which is used to obtain vehicle data, and then send it to the tablet for analysis wirelessly or via data cable.
2). When as a SmartLink C (Customer) dongle, it does not communicate with the tablet, but it needs to work together with the SmartLink module of the tablet. The tablet is mainly used to issue remote diagnostic requests, and the SmartLink C dongle is networked to receive and execute commands from the remote SmartLink B (Business).
3). When as a local J2534 PassThru device, it can be used in conjunction with the PC installed with OEM diagnostic software.
X431 PRO3+ SmartLink HD Functions:
1. ECU Programming & Coding
ECU CODING: Online Coding/Matching/Calibration/Relearn/Personalization/Retrofit/Customization
With ECU coding functions, LAUNCH X431 PRO3S+Smartlink HD will improve vehicle performance, customize individual customization, refresh hidden functions, disable the annoying functions, reprograms the adaptive data for certain components after repairs or replacements, customized configurations for high-end models,etc to enhance fuel efficiency and ensure safe driving.
- Online Coding: this LAUNCH scan tool can directly access the online vehicle repair data to do high-level repairs.
- Offline Coding: read the code from the original module, and then write the code for the new module,for example ,write a VIN to new ECU.
- Component Matching: Matching,relearn ,Cali-b-ration, or initia-lization adaptive data for certain components after repair or replacements,such as: suspension cali-bration ,seat matching ,sunroof initia-lization,gearbox matching,injector cali-bration, transmission adap-tion.Delete Adapt-ation Data, Tank Cali-b-ration,Height sensor system cali-bration,PSM Sensor Cali-b-ration ,etc.

- Unlock the hidden features: for example,disable auto start-stop, disable daytime running light, disable safety belt chiming ,delete transport mode,delete transmission adaptive value.setting speed limits,etc.
- J2534 Programming: Pairing with the SmartLink C V2.0 device (serving as J2534-Compliant VCI), you can operate a PC or LAUNCH X431 PRO3S+SmartLink C diagnostic tool to download OEM software and install J2534 files from LAUNCH official website, to perform the J2534 programming for some vehicles. Note: Reach us to get the J2534 Operation manual.
What can this J2534 Programming Function do for you?
(1) Operate OEM programming without using the OEM tools
(2) Replace ECUs: program blank ECUs
(3) Write-in Data: refresh used ECUs
(4) Repair missing ECU information
(5) Upgrade ECU software version
Audi /VW Firmware Protection Cancel Features: One feature most techs really want is to remove firmware protection from their cars. This feature helps mechanics replace car parts. Carry out car modifications.
(PMI) Programmable Module Installation: Support PMI function,Compatible with Ford /Lincoin/ Mazda etc.This function is used when you need to replace a module (replace ECU) or initia-lize a module.No need using the J2534 or buying a subscription.
Bi-directional Control: ( ACTIVE TEST )
This option is used to access vehicle-specific subsystem and component tests. Available test vary by vehicle manufacturer, year, and model.
During the actuation test, the display tablet outputs commands to the ECU in order to drive the actuators, and then determines the integrity of the system or parts by reading the ECU data, or by monitoring the operation of the actuators, such as switching an injector between two operating states.
For cars: Injector Buzz Test/ Idle Speed Adjustment/ Window/ Mirror/ Door Lock test/ Pump and Valve tests/ Fuel Pump/ Solenoid valve ,tank Ventilation/ Switch/ cylinder correction off/on/ EGR test/ EVAP test/ A/C Compressor Activation/ Turn on the radiator fan/Modulate the throttle/ cycling the a/c/clutch on and off/ Acceleration Device Test, etc (vary by car model, year )
For Heavy duty Trucks: Cylinder cut-out test/compression test/injector volume commands/injector programming/S.CR commands/rail high pressure test/S.CR catalyst regen/Cylinder balance test/D.PF regen/VGT calibrations/S.CR commands/Aftertreatment reset/Parameter changing/glow relay activation check/reset the D.P.F filter,etc.(vary by car model,year)
Power balance Test: Cylinder power balance testing can help uncover hidden engine issues related to engine misfires, lack of power or just a poor running engine, which is commonly missed with other tests. So, cylinder power balance testing, is one of the best and easiest ways to find the source of a engine misfire. Furthermore, cylinder power balance testing is often used along with a cylinder compression and cylinder leakage tests to further pinpoint the problem. **All above are not available for some specific car models. Reach us for details.
