* Is your Malfunction Indicator Light working?

* Can you tap out the appropriate code on the accelerator to get a
code readout on the MIL? (For example, see page EC-708:

* Does your OBD II reader work on a different vehicle?

* Does your OBD II reader display indicate that it is
getting power? (Open fuse to the OBD data link connector?)

* Do you have a copy of the shop manual for the car?

I've had the same situation - but not a Nissan - answers:
q1-yes.Q2-What?(not nissan - no way to get codes without reader)
Q3 yes
Q4 yes
Q5 yes

My rather limited (pcode only) reader would connect up no problem -
but the higher end scanner to read ABS and other "chassis" codes
wouldn't connect for love or money.
