Need help to identify type of my car's OBD
I have Daewoo Nubira 2 1999 (automatic transmission) ...
My Check engine light is always on , so I want to diagnose the errors ..
but I could not identify if my OBD is OBD 1 -1.5 or 2 and following which protocol.
I've attached pic. of my OBD Pins
Thanks in advance
Pins 4,5,6,7,9,16

I think it probably depends on what market (country) this was originally sold into. Seems there could be a few different protocols used in the global market. US market, it would be fully OBD2 compliant.

As far as the statement about OBD2 after '94, 1995 S-series trucks disagree.
Having pins 4, 5, 6, 7, 9, & 16 could be a match for ISO 9141-2 or ISO 14230 KWP2000 (CLICK HERE for the best collection of them I have found so far). At first it looked like it wasn't a match for these until I found the link above which said that pin 15 wasn't absolutely necessary for these two protocols.

I can agree that the connector is an OBD2 connector, however the pinout does not match US OBD2 pinouts and likely means that it does not work on the J1850 VPW or PWM protocol which is why I asked what market it was in. I agree that it should be OBD2, but other countries do not necessarily follow...

OBD-II protocols used on Daewoo Nubira 1999
ProtocolSAE J1850 10.4kbps (VPW)
The ELM-USB OBD-II USB interface and OBDTester diagnostic program support these protocols.
OBD-II connector pinout for SAE J1850 VPW Nubira
---------------------------------------------Also:
Most Daewoo cars in 1996-2001 are equiped with J1850-VPW protocol. After 2001 - KWP2000.
