So is the warning lamp still on with these readings? cos the system seem to work well as the main relay is on and the warning lamp should be off according to the inputs so it might be just a problem on the warning lamp's circuit... you should try with a known good ECU cos at this point is suspect
No the dash ACE light is not illuminated, as the Nanocom says too, the warning light is off. When the warning light came on it was accomapied by the ACE ECU faultcode 30-06. You could stop and start the car and the light would come on after a few minutes driving.
Yes you are right intermitents are a pain.
OK thanks SF, I'll clean that area up and investigate.

The filter was fairly clean when removed, but I have washed in petrol, compressed air blown out and re-installed.OK thanks SF, I'll clean that area up and investigate.
May I thank you kindly for all your assistance regarding this annoying problem, you are a star m8.
Yes, on an ECU drivers for devices can fail, that is true. On the drive this afternoon I monitored that current fed to the DCV1 and DCV2 as I cornered, the max I saw was just under 5 amps which for a 2.6 ohm winding would indicate the the ACE ECU relay driver transistors are operating pretty much full on OK. Minimum was 0 amps which meant that the ACE ECU was turning off the relay driver OK as well.
The ACE fluid is very dirty in the reservoir. Do you recommend a complete change for fresh fluid might help?
Wont hurt... prime the pump with outlet undone after you fill it
I am trying to get the ACE ECU out of the car to reveal it's part number, so I can get another one. I have removed the glove box and bottom facial trim but cannot see what is holding it in apart from one nut at the front. Does anyone have a link to a copy of the RAVE manua (all mine are now corrupt) or can advise me of the removal process.
Jesus this is difficult. I have found a lower nut on a sort of bracket that holds the BCU and ACE ECU togther, but that alone is not realeasing the two ECUs. It's nothing like the RAVE I have managed to open. Getting to the point where I'll kick this in to touch and forget about sorting the ACE ECU Pt No
Thanks as always SF.
That's very strange as the D2s were from XA..... which means starting from 99 to 4A which means 2004... you say your's is from 2003 so it shuld be something with 3A not 7A which means 2007, see this article https://twinwoods4x4.co.uk/how-to-decode-your-land-rover-vin-vehicle-identification-number/
