So your power light stays on after you change gears and press the power button on and off in the right sequence?

If so, you need to get a copy of page 41 and 42 of the AT section of Nissan's GQ workshop manual, it clearly explains how to test each of these components. No guesswork, just checking voltages at the TCU with a multimeter. It's a process of elimination.

I found this very tedious with our auto, but it was what led to fixing it.


So in less than a week this should arrive?
what was your fix? I've replaced the tcu no change, tried unplugging kickdown switch all that did was cause power light to flash several times when I started the car, powrr shidt switch is working fine, drops it back to 3rd when engaged havent tested inhibitor switch yet but got a second hand on on sunday and havent tested idle switch circuit yet, just cant get into diagnostic mode just get as far as power light staying on, which is error code "inhibitor switch, power shift switch, kickdown switch or idle switch circuit is disconnected or the control unit is damaged"
