KM4

The first three characters of every VIN are the World Manufacturer Identifier (WMI). The code KM4 is assigned to Suzuki, with the country of manufacture South Korea.

So any 17-character VIN that begins with KM4 was produced by Suzuki:

KM4ZZZ0000000000000

The WMI only identifies the maker. To read the year, engine, plant and serial number, decode the complete 17-digit VIN with our free tool — then check which ECU it uses and what tuning services (DPF, EGR, AdBlue, DTC off, Stage) are available.
