Hi everyone im new here ,have the usual disco problem (3 amigos)
Has had shuttle valve wiring bypass done ,and no faults showing up on the diagnostic, but the lights are still on ,also have amber ace light on but seems to work ok ,has anyone had this problem or knows how to rectify it ?
Any ideas appreciated
Regards shawn.

Hi. If no fault codes logged and the 3 amigos are on the first suspect is the ECU the second is the intrument pack or a wiring issue on the warning lamp's path, troubleshooting is needed... provided a reliable diagnostic tool was used. For the ACE also a proper scanner is needed.

Have you driven it? Sometimes the faults are cleared but the lights stay on until you drive it.

Hi thanks for the info ,ive had another go with my scan tool and found a fault in the sensor readings ,says the impedance on L/F wheel low ,so i checked the sensor with ohm meter at plug under bonnet and says sensor good . and to be honest it looks new im not that good with electrics so im abit lost now !

What resistance did you get on that sensor? ... it must be between 950 - 1100 Ohm

I got a solid 1122 ohms which abs buffs said needed to be between 800 - 2000 as a genral rule of thumb ,but im only going by what ive read so could be wrong ?

Fault said i had 1.28 impedance L/H where as R/H read around 3.90 and backs read around 9.00.

Next time read the workshop manual cos that 800 - 2000 is boll*x, 1122 is 22 ohm above the accepted limit

Ok thanks so do you think its probably sensor and hub then?
Are the non ome hubs ok ?
As they are a lot cheaper than landrover!

Heres a plan for you....

wire the sensor to the other side....as in leave the sensor where it is but wire it to the other side with lengths of wire....

Then recheck and see if the fault moves to the other side then you'll know for sure

You can buy sensors but more or less have to remove the hub to fit them anyway

I wouldn't buy the cheapest Chinese ****e you can find but there's no need to buy "landrover" either
