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

 

That should be OBD 2.

 

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.

 

I'm in Egypt, but the car were originally meant to be sold in The Arabian Gulf market

 

That's an OBD2 connection. Anything, no matter the manufactor or the market, if it's made after 1994 it's OBD 2.

 

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...

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 found this:

OBD-II protocols used on Daewoo Nubira 1999

Protocol

SAE 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.
