Thread: Discovery 2 TC

There's a missbalance between sensor signals, it can happen even if you mix different brand sensors cos admitted resistance of a sensor is between 950-1100 ohm and if one is at the lower limit and others at higher or vice-versa they'll past the system self test cos the stationary output is between 2.0 - 2.4V so no fault codes but in movement at the same wheel speed one input is higher or lower and the system interprets it as wheel slip

did you fit genuine or branded hub? if not did you count the teeth of the reluctor ring? cos some cheap chinese ones have 55 instead of 60 and that can cause issues too

you need nanocom plugged in to see which sensor is giving different readings

untill you fix it if it's very annoying you can remove the ABS pump relay(R10) then you'll get the 3 amigos and no ABS/TC activity... just be aware that the brakes will work normally like on a non-ABS vehicle which might not be bad cos even the ABS can be erratic due to this missbalance and then it can make you trouble rather than help you

OK, well the brand i bought is Optimal An german brand, and this is an dumb question but how do i count the rings? As i only see the spline on the hub?

If it's german product dont bother to count(you can count only through the sensor's hole) ... might be the sensor's resistance different...can't you fit the sensor from your removed hub for test?

a nanocom would be great help if you can find somebody close to you to help

I got an nanocom and here is what i found after an little test drive just now.

Voltage
Car on idle (standing still)
Front Front 002.19
Front Left 002.19
Rear Left 002.17
Rear Right 002.17

Car Moving
Front Front 002.21
Front Left 002.19
Rear Right 002.17
Rear Left 002.23

Wheel Speed (KMH)
Front Front 0008.2
Front Left 0008.2
Rear Right 0008.2
Rear Left 0007.5 ( HERE is the one i change to there German Brand Hub)

Put back the old sensor and see then... if it's the same it means that the german hub might have wrong number of teeth, might be a german hub made in china

And is it ok to unplug and unscrew the sensor and swap around?

Coz i read that it upsets it and its not good?

you can swap sensors either way as you wish, no problems with that

Well i counted the teeth is it 55 So I have to get an 60 tooth one,

Idk if this will help i bought 2 hubs including the one i change so would it be of any help to put that one on so the rear is the same speed but slower to the front?
