I have mine aligned every year, they never say anything about electronics calibration. But this isn't a dealership, it's a Firestone tire store. Maybe a dealership knows things the Firestone tire store doesn't, or maybe the dealership is trying to add more to your bill. Hopefully, someone with more knowledge on the stability control will chime in.

 

call him out...………….. and make sure whoever does your alignment does it to the Pfadt specs. here which ensure best tire life too...……..

 

Thank god that the dealers are figuring out that if someone slams the car to pull it out of corner balance, or you have major wear to the ride height bolts, it going to cause problems of how the car tracks as well.

As what the dealer was getting to, if you have F55/MRC on the car, then the quick way to tell if someone pulled it out of corner balance, is to check the ride height sensors.
The sensors with the car on level ground should be right around 3V's, and they should all be same/same in voltage for all the corners. So if one or more of the ride height sensors is off in readings from the other, then the ride height needs to be checked to get the car back to corner balance to start with, and then if still needed, the ride height sensors are adjusted to get them back to even with each other, so the F55 module is controlling the suspension correctly as well.

On none F55 cars, you can 4 point measure from the frame to the ground front and back to see if the ratios are still in order, and adjust the ride height adjusters if needed to get the car back to factory corner balance set up before aligning as well.

Once the car is back to corner balanced, the rest of the suspension parts check out fine, then the alignments is completed next.

Bluntly put, the C6's are all old enough now to have wear to the ride height adjusters, so pretty much any Vet that has not been checked in a while, really needs to have this done to get it back to at least the factory ride height ratio's of corner balancing. I'm not saying that the car ride height needs to be raised back up to factory ride heights if lowered, but the ratio of front to back heights maintained to hold the car at least at the factory corner balance ratio's instead.

As for if one of your ride height adjusters is on the way out, here you go for replacements of the the ride height adjuster.

Also to point out, since Active handling all revolves around the steering wheel sensor reading zero with the front wheels pointing straight, it behooves you to have an alignment done at a place that can not check the steering wheel position sensor to make sure it reading zero with the read out of the alignment front tires reading zero as well. Hence the shop that I take my vet for alignment does not have a Tech II/there alignment machine can not read the steering wheel position sensor, so I take my Tech II with me, set it up to monitor the Steering wheel position sensor, so the tech doing my alignment, can make sure to set the front tires straight with the Steering wheel sensor reading Zero as well.
Note, in some cases, the steering wheel position sensor may need to be re calibrated if it not reading correctly to start with.

As for alignment, if you drive the car hard, then have it done to factor specs.

If you DD/Cruse the car in your driving style isntead, then use the pure street specs isntead.
