Steering Angle Calibration
Having just had new front suspension arms fitted, I need to get the alignment done.
My indies normal place couldn’t get it as they were fully booked, so I took it into another recommended place with hunter kit.
Basically that company couldn’t get one of the track rod ends undone, so they gave me the car back, with some adjustments made. I spoke to my Indy and they said bring it back and they would free it off, fairly common!
So left alignment place, steering wheel pointing now point at 2 o’clock, with wheels straight. After 5 mins, got all the warning lights, and car lowers.
So, I think it’s because the steering is off centre, and needs calibrating.
So my question is, can I calibrate the steering sensor with the steering set at 2 o’clock and wheels straight until I get the suspension alignment done to avoid alll the warnings, then calibrate it again after alignment when wheels straight, and everything correct?
I’m getting it sorted tomorrow, but have about two twenty minutes journeys between the different garages and don’t want to drive around with no suspension and warning lights?

Its a good question but I imagine nobody has deliberately miscalibrated one before. yµ (idµ - eAµ) ψ=mψ

Very strange to have the wheel that far off-centre.
If you have an IID then you can just set the calibration with the wheels straight, irrespective of wheel position.
Without it there are 2 options, but seeing as you presumably can't budge the track rod yourself there's effectively one option:
The steering angle sensor collar on the column is a friction fit.
It is possible to rotated it on the column to get the reading aligned with the way the wheels are actually pointing. It's not precise or desirable but I've done it in an 'emergency' once before and it stopped the bongs and suspension lowering etc. In that case the collar was already a bit loose (common) and had slipped on the column by itself. If you have the off-road screen you can check where it is when the wheels point to each side of centre and then position it in the middle of the range.
Pathetic for any place that does alignment to not be able to free a track rod though.Black 05 TDV6 HSE Auto

Yeah it’s a pain for sure! My Indy said the alignment place were lazy not freeing off the track rod!
Not really keen on moving the sensor, I would rather just calibrate it wrong if that works. All a pain!

Good god there's a total mash up of advice here.
Rob, all the steering angle sensor does is tell the car where straight ahead is. This allows the car to set up the suspension and steering dynamics so everything runs smoothly. After you've had steering or suspension work done, the car will need to be told where straight ahead is again as it will now have changed. You re-tell the car by recalibrating the steering angle sensor which in effect, resets the straight ahead position. There's nothing simpler than that.

Thanks Narpy.
So I will recalibrate the angle sensor with the wheels straight and steering off until I get the alignment completed properly, then recalibrate it again with the wheels and steering wheel straight.

Yep, that'll all work out fine.
It will need resetting once the steering wheel has been recentred.Mods:

Didn't see that you had the IID sig earlier, although presumably you would have stopped at:

I did find being able to 'adjust' the sensor when it had gone out of adjustment due to slippage (very much before I purchased an IID) was handy.Black 05 TDV6 HSE Auto
