I haven't driven my '07 in a few weeks. Drove about 3 miles to dinner. Nothing out of the ordinary except when making a right turn out from my subdivision, the car felt like it lost traction and the rear end just swung around in the turn under normal light acceleration. Didn't fish tail. I just thought I was imagining things since it had been a while since driving it.

After dinner, started the car to go home and the DIC read "Stability Control Calibrating." A couple of seconds later it said "Stability Control Ready." I have never seen this since I bought the car new.

Note: Not a battery problem since I keep a battery tender connected and this is only 2nd summer for this battery. Car started right up.

 

check you tire pressure...could be a couple lbs. low, especially with lower ambient air temps.

 

Just checked and all four corners are at 28 psi. Could be the problem. I'll hook up the compressor in the morning. Thanks.

 

mine were the same (cold tire temp.) this morning...aired-up to 31 psi all-around.

 

Perfectly normal operation. Read the Owner's Manual. One of the key pieces of information required by Active Handling is where the steering wheel is pointing. The system develops this information after each engine start. It does this when the car is traveling in a straight line for a certain distance above a speed of 6 mph or so. Once it knows the car is driving in a straight line it locks in the steering wheel position from the steering sensor. If you make a turn before the car meets the requirements to lock in the information you get the calibrating message.

Not sure of your differential oil life (when it was changed last), now would be a good time to change it so there is fresh fluid in the diff.

The down and dirty, the LSD in the vet is not the best in the world. Yes, it works great to lock up/ spool the back tires together when needed, but when coming out of a turn and pushing hard, the inside tire will want to turn as much as the outside tire, causes the inside tire to spin. When you are not on the power, then the inside tire should spin less than the outside tire without the LSD locking the two tire together.

Now back to lube, and with dirty lube, the LSD pads want to grab more then normal in the unlocked position since the fluid is contaminated with LSD clutch dust. And instead of the inside tire allowed to rotate slower than the outside tire in a turn when you are not pushing hard out of the turn to cause the LSD to lock up, the LSD is acting like its locked in the unlock position since the pads to separators are not slipping against each other like they should be instead (clutch pack dust in the lube causing the pads to have more bite against the separator discs then they should normally have).







As for the Stability Control Calibrating message, kind of a normally thing as the temps start to drop and the system is activated to correct the car. The car is just checking all the outputs of the sensors to make sure that they are in the correct ranges, and when done checking, you should get the completed message. In your case, the back end coming around caused the Yaw nanny to kick in to clip the power to straighten out the car, and then the system did a quick check on itself afterwards to make sure that the system was running correctly. The back end coming around could have been from you give too much power for road condition (tire grip on colder roads/colder tire rubber have less bite/ lower air pressure in the tires), but at the same time, could have been because of contaminated fluid in the diff that did not allow the pads to normally slip in the unlocked position when you are are not hard on the throttle instead.
