ride height sensors, setting with hawkeye

put new ride height sensors on, passenger side problem with plug, stuck solid, have got it all back together but car lists to the pass side, hawkeye says
sls RR count 95

sls RL count 152

car is sat on level ground , but when it raises pass side stays lower,
how do you reset them?

Hi there,

Did you disconnect the battery before you started this?
Not sure about the Hawkeye, but on the nano, a reading of approx 148 +- a few , is normally correct, measuring the distance to the std does show that one side can be 149 and the other 147 to give the correct ride height on my motor.

Are you sure you position them in the correct orientation? I found this on someones as it would not raise when they changed sensors, took it off refitted so that it was angled the other way and it worked. Although in that case the "dodgy" side had a reading on the nano of iirc 250.

Others have jacked the rear of the vehicle up to "normal" height to get it within its working parameters. Start the engine and it may reset.

Cheers

took battery off, dodgy connection when i re connected, i have dropped the sus to the bottom, have got a reading of 94 RR,
loosened and propped the RL and have got same reading, took battery lead off, waiting now 10 mins to re connect to see if i have foxed it?

I must be having a dumb day, because I do not follow what you have written.
Have you tried jacking it up manually and then starting the engine?

Cheers

the hawkeye setting on the display when car is sat right down read
RR count 94 right handside
RL count 152 Left handside
so i undid the RL and messed around with the sensor arm to get a reading of 94, then disconected the battery, so hoping it will of registered in the slabs as both set at 94 when reconnected,

OK,

That makes sense,...LOL
Have you measured the actual dimension? when it is normal mode. iirc it should be 473mm +-15mm wheel ctr to the bottom of wheelarch.

Cheers

I have read on one forum that you can make your own blocks - which should be 61.5mm (or thereabouts). I cut a couple of blocks of wood and positioned them between the axle and bumpstop. When I used the lynx to calibrate the suspension it didn't work because the new bumpstop I placed on the passenger side rested nicely on the block, but the old bumpstop on the other side compressed. I have another new bumpstop and when I get back from holiday I will fit it and try again. I have new ride height sensors but the old ones seem well rusted on.

I just find it easier with the nanocom to measure / adjust / remeasure / save. Job done.. I always assumed that the Hawkeye would do the same.

Cheers

It might seem a silly question,but what is the best way of getting your tape measure under the wheel arch and then measuring in a straight line to the ground?

you do not.
You measure from the wheel hub ctr to the bottom edge of the wheel arch. It is pretty much a straight line.

Cheers

Go to a supermarket or any other parking place on straight ground, jack it up from the towbar or(use two jacks one each side of the body) as the level of the body to be perfect then go with hawkeye in calibration menu and when it asks about calibration blocks fitted prompt yes then confirm and the target heights of the sensors will be saved at that level, neglect those figures shown as heights cos they are irrelevant, they can differ from one vehicle to another according to sensor's brands, circuits resistance, battery voltage etc.

got it jacked up at 470mm centre of wheel to the arch, got same reading on the hawkeye, but how do you save them?

You dont save those figures you save the target height inputs at that level.... in the calibration menu following the steps hawkeye will ask for calibration blocks then prompt yes and confirm... i've already told you that

mine does not ask for that, if you get the count at the same number, then take the battery lead off, will it not save to that number. i have the amber ride height lamp flashing bottom of instrument panel

Is you hawkeye at least v.6?...if not forget about calibration and if it is it must have the calibration capability...taking the battery lead off will not save anything whatsoever

that i will have to look at! found out it was in transportation mode,

When you plug it in you'll have to see on the screen after it starts what version of software is loaded in it, if it's v.6 in the "Chassis" menu go to ''Programming'' and there it is "Calibration" at 3'rd line

i have it now jacked up at 470mm, both ride height sensors set at 157, i have left it like that,took the battery lead off, is that not the same way as you would swap one for a new one?

Taking the battery lead off means that the initial stored heights will not suffer but if there was a problem with a plug and the system got erratic inputs once in most cases a recalibration is needed, even if the new sensors are different brand than the old ones a calibration might be required, disconnecting the battery is just a caution it doesnt save new inputs at all

so how does the sensor work? so not all straight swaps will work either?
