I was planning to do that as soon as most of the snow has been cleared from the streets. I is stilla mystery as to why there is no action on the output function on the Nanocom. Do you think there would be any merit it removing the ACE pump and stripping it down to see if there is anything...

I just checked for continuity for the two wires attached to the pressure control valve solenoid and there was contiuity. Obviously the system has air in it, but the Nanocom bleed function doesn't seem to function. I can see air bubles in the reservoir when I run the engine. I am still scratching...

I will continue to scratch my head and maybe something will come up. BTW the new valve block was thorough cleaned and the solenoids and valves were checked for operation by connecting to a battery before installing in vehicle. I will check continuity of the wires from the pressure control valve.

Are the ECU's the same for all Discovery 2 models? The number on the new (used) ECU is CKA08BMD wheras the original ECU is CKA06176F. I don't know if this is a part number or a serial number. I did download the software again but not difference. The pump is new and sprays lustily when the banjo...

I changed the pipe but no change. The system is obviously full of air, but the Nanocom outputs still do nothing and the bleed fucyion does nothing. I also reloaded the Nanocom software. I can't believe it is the pump becaause it was changed for a brand new one just befor I took ownership of the...

Does your high pressure pipe have and integral attenuator?

will check

Unfortunately, the supplier sent the wrong pipe. I have ordered a correct on from LR Parts in England. I still don't understand tha when I trey the output "warning lamp" in outputs on the Nanocom, I get no reaction evem with the new ECU.

I did the testand there definately was more circulation in the reservoir, but nothing like in the PAS reservoir. If I crack open the banjo joint on the ACE pump it squirts significantly. This leads to believe that the problem is a damaged attenuator in the high pressure pipe. I have ordered a...

What you say makes sense. I will try test as soon as I am able.

Again, your comments are invaluble. I will do as you suggest. As mentioned in my itriductory profile, I completed a ground up rotisserie restoration of a 1965 Jaguar E type. Attache is an image. The electrical diagram is only one (1) page. Life was simpler then. I underline that I am a hobby...

I hear you. Hindsight agrees with you. However, after changing all the hydraulic pipes, new ACE pump, new (used valve block, new front actuatorand new (used) ECU, new "blue" pressure control valve solenoid and the directional solenoids test correctly, I am reluctant to have the problem get the...

Thanks for the video. Compared to the video I have almost no movement in the reservoir. With regards the values shown on the Nanocom, I have the following: Pressure sensor: 016.44 vs 18.76 Residual pressure: 000.34 vs 6.47 System pressure: 000.34 vs 6.45 It appears that my system pressure is...

I bought a valve block from the same supplier from which I bought the ACE ECU, It is verry clean and looks to be in excellent condition. Before I change the valve block entirely, I will try another pressure regulating valve. I will also check the high pressure pipe to see if there are any...

Thanks for your comments. I will have a look when I get Hank (that's his name according to the previous owner- Hank the Tank) back up on the lift.
