Just got my nanocom and have a few questions....

I seem to have got the last one in the country (from Famous Four) - cheaper than the last one that sold on ebay! I've set it all up - very straightforward, especially compared to the similar Tuneboy I use for my Triumph motorcycle.

But I could do with some help with the codes I'm getting. These were with ignition on but engine not running:

The SLABS ecu contain the following faults:

FAULT 01-01 No fault logged in the ECU register 169 times
FAULT 29-08 rear right corner valve duty cycle exceeded (LOGGED) 254 times
FAULT 32-06 plausibility fault raising rear right (LOGGED) 254 times
FAULT 32-08 compressor duty cycle exceeded (LOGGED) 254 times


The TD5 ecu contain the following faults:

FAULT 01-07 EGR vacum modulatore schort citcuit (INTERMIT.)
FAULT 02-08 ambiant pressure circuit (CURRENT)
FAULT 03-07 air flow circuit (INTERMIT.)
FAULT 10-03 tachometer open load (CURRENT)
FAULT 10-04 gearbox/abs drive open load (CURRENT)
FAULT 19-03 CAN tx/rx error (CURRENT)
FAULT 20-04 EGR valve stuck open (CURRENT)
FAULT 22-01 road speed missing (CURRENT)
FAULT 31-01 injector 1 open circuit (CURRENT)
FAULT 31-02 injector 2 open circuit (CURRENT)
FAULT 31-03 injector 3 open circuit (CURRENT)
FAULT 31-04 injector 4 open circuit (CURRENT)
FAULT 31-05 injector 5 open circuit (CURRENT)


The ACE ecu contain the following faults:

FAULT 04-07 ELECTRICAL FAULT IN DIRECTION CONTROL VALVE 1 CIRCUIT (FAULT 31) (CURRENT)


I assume a lot of the engine ones are because the engine wasn't running. As far as the SLS is concerned, I have had the light flash a few times and on investigation discovered the filter in the rear pillar was a solid block of ice and the fuse had blown (I assume because the compressor overloaded). I've replaced the fuse. I am a bit worried about the compressor duty cycle exceeded one - does this mean it's reached the end of its life or has it just tried to run that many times then given up? I particularly like "FAULT 01-01 No fault logged in the ECU register 169 times"........

I've reset all the codes but for various reasons can't drive the car for a few days. I've just started it up and tried the raise function and that works very well.

Any suggestions very welcome.

you need to give it a drive now you've cleared the fault codes. A lot of those look like they could be caused by oil in the loom (injector ones give it away!).

I've just had ' the compressor duty cycle exceeded ' code on mine and the compressor is only 5 months old! My mechanic cleared all my faults - caused by frost - and everything is now back to normal - it was the solenoid that had 'blown'. I was told that there is a 'protection' on my 2000 disco2 td5 which cuts in to stop the compressor constantly working when a fault has developed in the suspension system.
I am just a long-in-the-tooth Disco owner of the 'fairer sex ' who knows very little, except how to keep signing cheques for someone to look after my vehicle, but just love mine to bits. Have had LR's for over twenty years now and am very dependent upon my brilliant local mechanic.

Hi Derwendolly,

Yes, I'm sure it was the frozen water clogging up the input filter that caused my problem - it's interesting what you were told about protection, and maybe that's why the raise function didn't work on mine till I'd cleared the fault codes.

I dismantled the filter and dried the 2 internal elements out on a radiator till they were absolutely bone-dry. I'm also going to rig some sort of shield in the pillar to stop all chances of water getting in there.

Reporting back as promised - have now driven the car and rechecked and all engine and SLABS errors have disappeared. However, the ACE error:


FAULT 04-07 ELECTRICAL FAULT IN DIRECTION CONTROL VALVE 1 CIRCUIT (FAULT 31) (CURRENT)

is still there.

Any ideas? ACE seems to be working fine and it's never thrown up a warning light.
