An OBD2 compliant vehicle can use any of the five communication protocols:
SAE J1850 PWM Search
SAE J1850 VPW
ISO9141-2 Search this site...
ISO14230-4 (KWP2000)
ISO 15765-4/SAE J2480.
there are many auto code readers support these obd protocols. Categories
you maybe can see that Some websites,personal blog say they support 9 or even more
protocols. This is because they mistakenly count protocol variants as separate Auto Code Reader
communication protocols. in fact,If you add 4 variants of CAN-BUS to our list, you are on 9. auto key programmer

2. ISO14230-4 (KWP2000) Programmer user manual pdf
Very common protocol for 2003+ vehicles using ISO9141 K-Line. Uses pin 7. download
Two variants of ISO14230-4 exist. They differ only in method of communication initialization.
All use 10400 bits per second.
ISO 14230-4 KWP (5 baud init,10.4 Kbaud)
ISO 14230-4 KWP (fast init,10.4 Kbaud)

ISO 15765-4/SAE J2480
AutoOBDTools
The most modern protocol, mandatory for all 2008+ vehicles sold in the US. Uses pins 6 and
14, communication is differential.
Four variants of ISO15765 exist. They differ only in identifier length and bus speed:
ISO 15765-4 CAN (11 bit ID,500 Kbaud)
ISO 15765-4 CAN (29 bit ID,500 Kbaud)
ISO 15765-4 CAN (11 bit ID,250 Kbaud)
ISO 15765-4 CAN (29 bit ID,250 Kbaud)
Other non-OBD2 protocols
Almost every car uses also vendor-specific diagnostic protocols such as KWP2000,
KW1281, VWTP, KW72, KW82, which are used for “native” diagnostics.
