Easydiag + 24V to 12V adapter = HD Module for trucks? The easydiag 12V to 24V HD adapter has been a while since it was released, it is advertised it would do HD modules’ job. There are two most frequently asked questions:
1.) It works both K-line and CAN Bus?
2.) Does it have the database for heavy duty trucks?
Answer and Suggestion:
1).
The 12V to 24V heavy duty adapter has no component for kline. Only usable for diagnosis via CAN.
It only converts 24-12V, no protocols, so only CAN will work.
On trucks with CAN line is not so bad.
On trucks with K-line (old) none working.
Using easydiag with USA 12v trucks obd2 no problem and don’t need a voltage converter, but when i try to use an obd2 to 9 pin adapter to read the older trucks (K-line) it will not connect.
2).
It does not have a database for heavy duty.
Only buy original launch x431 24v truck adapters with separate software.
You can use HD or HD III for X431 V+, Pro3 or Smart Box for Pad V, SmartLink for PAD VII (PAD V, PAD VII need to purchase truck software in “Mall”)

So if you need to diagnose CAN BUS truck, the easydiag converter is worth a try. Trucks are very expensive, original Launch HD adapter is definitely the best solution.
