Ok, heres what my friend says.. Which its not making sense.. having decoded my 4th gen. i would think it would be pretty similar on his 3rd gen? Did he miss something? He says it blinks at the same speed. and they blink at the same time
He has an 89 maxima.

The Red and Green LED's blink in unison.
Im told the sequence he decoded is:

both lights.....

blink
blink blink
blink blink blink
blink blink blink blink
blink blink blink blink blink

I know 12345 would not be correct. Any ideas?

 

Congrads you have decoded the "Modes"

 

can you please elaborate? what step did he miss or what does he need to do to decode the problems with his car?
