I have a 96 Sentra with a 1.6 liter engine.   I had the trouble code
show up on the dash today as I was working on an overheating problem.
I wanted to determine what the trouble code was by accessing the ECM
and having the codes show on the indicator lamp.   I checked my shop
manual to find the ECM.   It showed that it is located adjacent to the
gas pedal in the left portion of the center console.  

I tried to access the ECM this morning and I am having a great deal of
trouble removing the plastic piece that covers the location of the
item.    I tried removing the radio and AC controls from the center
console to access the ECM from the rear.    Though I was able to
remove both the AC controls and radio, I couldn't figure out how to
remove what I think is the ECM to work with it.

Here are my questions:

1.  Am I right that the ECM is located where my manual says it is?

2.  If the location is right, how do I access it?

I would appreciate any assistance you may give.

Thanks,   Al Kondo
