Nissan Altima: 1995 Altima computer codes

Yes. You've found it. No knob but there is a screw driver slot under
a piece of transparent tape. You should find the slot in the
10:30\4:30 position stop and the next stop should be at the 1:30/7:30
position. Be careful the stops can break if excessive torque is
applied afterwhich the screw will turn no end.

OK. Thanks for the reassurance. My eyesight was letting me down while
trying to look at this thing from an awkward angle.

Now is there an LED on the computer itself to watch? The reason for asking
is that the check engine bulb recently burned out. Replacing it will be
another task.

An error code(s), or a 5 long 5 short no stored code, will be signaled
via the check engine lamp after the screwdriver slot is moved from the
first position to the second position then back to the first position.
Multiple error codes will be given in sequence. You must replace a
burned out check engine lamp in order to see the codes unless you can
figure a way to access the circuit path and intercept with a meter.
