im abit in the **** with a scania double drive R440.

for some reason its a massive problem and i can't despite 2 days of everything iv tried to do it, will not fix.

i changed the clutch and sorted the PTO after it come up on the dash with the light, so rectified that.

the problem is it will not use low range gears at all, if you put ignition on in low range it works then if you switch to hi range and back to low it constantly goes to a default setting and keeps it in hi range.

i changed a few leads around and pluga and messed about even trying to use it with swapped plugs and without the solonoids connected, but still nothing, then for some reason there is power to the plugs and the solonoids but then only to some cables in the gearstick,

so i pulled out the dash passenger side and unclipped the gearbox connector at the bottom of the stick, and tested with a multi metre all the power outlets and plugs, to see if a can find the blue brown and black cable feeds to the connector in the gearstalk, but can't find it, then used the same method on the circuit bourd on the top of the dash where all the fuses are kept, still nothing, then also pulled apart the bit under the passenger windowscreen to the circuit boards there and still all worked. apart from i couldn't work out why there was power at the gearbox but not by the stick in the cab.

i tried to changed the solonoids over to work them backwards to get it to do something and still sweet f.a.

the dash displays gear box malfucntion but everything in the gearbox and the machanicals are completely fine it just will not use low range,
