Im not sure if this has been posted before... but searching through random sites about z's I came accross this interesting little page...

Its how to use the ECU diagnostic mode yourself instead of taking it to a dealer and spending $$$

 

yup
it's on tt.net's tech page which is also in my Link Page.
it's a good writeup.

 

If you intend to work on your own car over time, the tt.net tech and faq pages should be at the top of your bookmarks list.

 

the self diagnostic test never lies and only takes minutes.

 

I can do it in less than a minute it's so easy....

 

First it was a 5min procedure now you can do it less than a min...you must be practicing=> NapoleonZ your funny

 

Naw I just decided to leave 2 of the bolts on the floor panel out.

 

I went to the link on ECU Diagnostics and read the procedure. It noted that some, but not all of the ECU readings will also cause the 'Check engine' light to come on.

Since I have never had the 'Check engine' light to come on, does this mean that all of the components which would cause the light to come on are working properly, or not?

I apologize for all the questions, but most of the experience I have had was on older cars... and I am fairly new at diagnosing electronically controlled engine components, so I do appreciate your patience with me.

Thank you all for your help on this
