Thanks I will study it and try to effect checks. I do however notice that it states 'Maxima GXE' as well as '300ZX' My model is '300 SE' and I dont know if it is the same. Also numerous references to "Fig." Is there somewhere that I can view these plates/drawings?

Should be similar no matter what the model says.

I have sent a new file with the diagrams.

Thanks for information. However I have again gone through the whole system and chacked every fuse, relay, switch, actuator, Sensor, pump etc and can not find the fault. What is evident is that when I switch the car on and switch the ASCD main switch on and off one can clearly hear the relay under the hood swtched on (Activated) and off (deactivated. It seems the problem lies beyond this point in the system.

There is one item that I can not identify from the repair manual and no one can tell me what it is and what it does. It looks like a small relay but has only two connectors. There is no continuity when tested with a meter. It is connected to the sysyem with a Pink and a Red wire. Could it be faulty? See my attached photos

The schematic does not show any connectors for a Pink and Red wire. The component you have shown seems like a Diode. Did you test for continuity by reversing the polarity of the ohm meter?

If you have gone through the repair procedures, you should have come to a conclusion, I don't understand why you can't find the fault. A certain result should be be wrong or it tells you to replace the control module.

I have given up in disgust with the cruise control. You were right in your assesment that the 'unidentified' unit was a diode. It works in the door entry light system However I have another request please. Have you got a schematic drawing that shows the assemly breakdown of the air (throttle) control valve return spring assembly. Thanks (See image)
