What Points Should Be Noted When Purchasing A Car Diagnostic Scanner?

*Vehicle Model:

It must be clear which brands are supported (European, American, Japanese, Korean, domestic cars)? Is it comprehensive coverage or mainly focused? Does it support commercial vehicles ?

*System:

Which systems are supported? Must it be full system diagnosis (Engine, Transmission, ABS, Airbag, SRS, etc.)?

*Special Functions:

Such as: Programming/Coding: Matching new parts (such as ECU, dashboard), unlocking hidden functions. This is a high-value-added function.

*Service Light Reset:

EPB & SAS Reset: Necessary operations after brake maintenance and four-wheel alignment.

TPMS Reset, Battery Matching (BMS), Headlight Adaptation (HLA), etc.

*Hardware Quality and Design:

Main unit workmanship:

Is the material durable? Is the heat dissipation good? Are the interfaces (such as USB, Ethernet, SD card slot) firm?

*Screen:

Size, resolution, brightness (can it be seen clearly outdoors), is it a touch screen (and touch sensitivity).

*Connection cables:

The quality of the diagnostic connector (OBD2) and cables is crucial. Inferior cables are prone to breakage, causing signal interruption and diagnostic failure.

*Internal hardware:

Processor speed, operating memory (RAM) and storage space (ROM) determine the running speed and future upgrade potential.

*Software and Updates :

Operating System: Is it Android or Windows? Android is more common, and app-based operation is more convenient.

Update Method and Cost: How to obtain updates? (Online update, download to SD card/USB update). Is the update free? Is it lifetime free update or annual payment? How much is the cost?

Update frequency? (Monthly, quarterly?) The update speed determines the ability to support new vehicle models.
