Thanks for the commentary. I will roadtest tomorrow.

I plugged in the replacement ACE ECU today. The only difference was that there is now a reading of 000.01 amps and both DCV1 and DCV2. With the old ECU the value was 000.00 amps. All the other values were within the same range as each other. The same was true when I removed the relay and bridged...

I have another revalation, I changed the filter in the valve block before I installed the used unit originally a couple pf months ago. While waiting for the new (used) ECU (which I will pick up in Mooers NY tomorrow), i decided to have a look at the filter. It was full of black particles which I...

Can you confirm the position of the high pressure line from the pump to the valve block? I believe it is at the bottom of the valve block on the RH side as you look toward the rear of the car. Would you be so kind as to confirm?

I am having trouble unplugging the ACE ECU. What is the trick?

How much movement of the fluid in the reservoir at idle is normal? Should it be as aggressive as in the PAS reservoir? There is very little movement in my reservoir.

Thanks for the update. The "new" ECU and valve block have been shipped. I should have them next week.

What you say makes sense. ECU has been ordered. I also ordered another valve block just in case. From the photos it appears to be in excellent shape and it is guarajnteed. I think I wasted my money on the valve block but good to have a second spare.

I will order today

The warning lamp test did nothing.

If the ECU is bad, I wonder what made it fail since it worked before I replaced the hydraulic pipes. Perhaps when I stupidly reversed the bottom two pipes on the valve block?

I will order an ECU. Are the solenoid drivers part of the ECU?

I did the test yesterday with the relay installed as you suggested with the same result. Nothing happened when I pushed the on button for the light or any action from the valve block solenoids. The relay functioned in the horn slot (R15) and I checked the operation of the relay itself. I also...

I did as you suggested, bridged the relay #R14, and tried the outputs and nothing happened when I pushed the "on" button on the NANOCOM screen for the diectional valves or the warning light. I assume this is waht I am supposed to do for the test. I did verify that power was at the relay and also...

I put a jumper in place of the relay and got the following results: Engine speed: 750rpm Battery voltage: 14.28V DCV1 (amp): 000.0 DCV2 (amp): 000.0 Pressure control valve (amp): 000.13 Pressure sensor (bar): 016.11 Residual pressure (bar): 003.88 Upper lat acc: 000.00 Lower lat accc: 000.20...

Will do

Yes. I changed the filter for a new one. The motion in the reservoir is nowhere near the motion in the PAS reservoir. Thanks for that information. Do you think that when I I switched the two bottom hydraulic lines by mistake on reassembly the attenuator in the pipe from the pump got jammed and...

BTW the report from the dealer said that the problen was that the syestem needed bleeding. That is when I bought the NANOCOM. I went through the bleed procedure but never had the feeling that it did anything. I then paid a ludicrous amount of money for the dealer to bleed the system. Their...

OK. I will try to get to it later in the day. THANKS
