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

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.
