As can be seen, the CRP919 EV and PRO3S+ EV are basically the same in terms of software functionality, but the PRO3S+ EV is equipped with a more intuitive topology interface. Furthermore, the PRO3S+ EV supports more hardware expansion, and with the help of relevant tools, it can achieve even more functions.
The PRO3S+ EV expansion modules are as follows:
TPMS: i-TPMS, CRT5011E, CRT5011 V2
ADAS: X431 ADAS PRO PLUS (Need X431 ADAS Function License)
02-1 Scopebox Tester Oscilloscope
02-2 Scopebox Tester Oscilloscope (4 Channels)
S2-2 Sensorbox Tester Oscilloscope (2 channels)
Video Scope: VSP-600 Video Scope
Battery Tester: BST360 Battery Tester
Multimeter(EM 101N)
Current Clamp
IMMO Programming: XPROG3 IMMO Programmer
On the other hand, since the X431 PRO3S+ EV comes standard with SmartLink C, we can use remote diagnostics and it is compatible with the original software via J2534.
It’s worth mentioning that the X431 PRO3S+ EV supports diagnostics for various types of vehicles. Commercial vehicle, passenger vehicle, and motorcycle software packages can be purchased in the store (only electric trucks and electric motorcycles are supported; hybrid vehicles are not).
Electric vehicle diagnostics is a relatively recent development, and many technicians start from scratch. The PRO3S+ EV also offers free access to repair cases and operating techniques. If needed, you can also subscribe to the X431 FIX database (which requires a subscription).
As can be seen from the information above, the LAUNCH X431 PRO3S+ EV represents a significant upgrade compared to the CRP919 EV. The versatility of its expansion modules and support for remote diagnostics make the PRO3S+ EV an excellent choice for both professional technicians and beginners.
