my 1998 car has the OBD 2 diagnostic port under the steering wheel in the lower dash. My 1996 car doesnt, is it OBD 1 in the earlier cars?, where is it located and how are the codes read if it is OBD 1?
cheers

 

It isn't OBD2, on my MY99 impreza it isn't even OBD1. but some Subaru protocol.
Here, read this thread, tells you all about it.

The Datalink port will probably be yellow and situated under the dash near the steering column

 

I have OB2 in my 1998 Impreza and 2000 Impreza.

 

Don't you need a SSM.

 

MY96 is four small plugs under the column, two male, two female. Plug them together, turn ignition on, you'll hear clicking and fans cyclings and read the flash codes from the check engine lamp flashing a morse code.

OBD compliant connectors didn't become mainstream on cars until after 2001...mandatory as parts of EU3 regulations.

MY97 UK cars did have a 9pin connector as well but I think that's for immobiliser/key coding and maybe ABS and airbag diagnostics...But you still pulled engine fault codes as pulses via the two pin connectors...select monitor would just count the pulses. plugging the one connector together just connects the pulse wire to the check engine light instead and the other puts the ECU into diagnostics mode (pulses solenoid/cycles fans).

Code tables will be floating somewhere on the net.

 

thanks, that link works and is the thread I found when I searched
I didnt see anything in there that helped with the 96 car though
I have one of the bluetooth obd2 code readers that I have tried in the 98 car but its not connecting with my phone so I will look for a better one

 

thats great, thank you

 

thank you, thats helpful
its a 96 gravel express so I'll look for the yellow plug / 4 small plugs

 

Yea done that on my 2000 classic before I bought a OBD2 diagnostic machine.
