So, I have an amber error of the ACE system and would like to have a go at fixing it. Nanocom returned the following:

(40) Sensor supply signal out of range
(44) Battery voltage too low (main supplty voltage out of range for 614 seconds) - not sure why, battery is in fact good.
(Masked fault) (48) Main relay test has failed

I have slight leaks from the actual actuators and a very slightly leaking valve block, so those are the first things i guess. Will I need a nanocom to replace those things to be able to properly flush and bleed the system? Doubt is has proper ace fluid in there so I would flush it even if I do not fix all the leaks right away, just to protect the system from further problems

Also, to fix the leaking valve block, do I need a new valve block or can I get away with a seal kit (RVW100010). It is leaking from the pipes going into the block from the engine side.


let me know

I also have a leak on the pipe coming into the ace valve block. Where you able to fix it? And if so, how ?

 

ACE system - what fun!

This is what I did to fix my leaky valve block:

I had the same problem, except my ACE light would go to red and blink with a chime. It would continue until I shut off the engine, waiting a few seconds and restarted. It would do this when waiting in traffic jams, stop and go type driving. I had a leak in the block, due to corrosion of the aluminum according to a local LR indy shop. So led it all with this a rebuild, redesigned ACE block from Design and Development Engineering, Ltd. https://www.designdevelopmenteng.co.uk/.

installed easily, and comes with new valves, filter and sensors. Works great!


Rebuilt ACE block

 

Hey markdeg,

Can you explain how did you fix this problem you had a year ago with ACE amber light and error saying: "Sensor supply signal out of range"?

Thanks!

 

i forgot what the fix for that particular problem was but at the end i replaced all the hoses and fitted standard bsp fittings to solve the leak, changed the ecu to fix an intermittent amber light and then i also needed a new transducer as i had an intermittent red light. i suspect the out of range issue was the transducer

 

Did you replace the battery? I have the same problem (DTC40) and I think it could be the battery

 

no i had not changed the battery and thankfully it has been fine ever since. ace is awesome and really glad i invested a little time and money to fix it properly rather than just bin it

 

also make sure the orange plug under the coolant reservoir is clean as that might cause issues. if you have a nanocom you can test by checking the ranges but you need to bridge the relay connector as described in this thread.
