Stayed on, would not reset, going in for service.
I'm getting awful familiar with the roads between my house and the dealership. 650 total miles---120 of those spent going back and forth to dealer. Hopefully all the bugs will be worked out very soon, Looks like a top down weekend here in Maryland.

Thread revival!

I parked pointed uphill with the front wheels looking at a big speed bump. When I went to leave it was raining heavily and the bump became a chock against the front wheels. Traction control is still new to me so I decided to see what it'd do if I tried to get over the bump. As I applied more throttle the rears increased spin until I hit 1500 RPM regardless of more throttle. However, a second or two after hitting the floor, I got DTC's set, traction control turned off, "service traction control ESC" appeared, and the rears quickly spun up to over 3000 RPM before I got off the gas. That was a surprise because being stuck and someone flooring it should be the condition where traction control is really needed. My girlfriend is someone who will do this, for example.

The codes turned out to be left front and right front wheel speed sensor failure. Makes sense that traction control can't operate without those as inputs but zero speed, low traction, and full throttle seems to be the obvious case where wheelspin needs limiting. I cleared the codes, restarted, and everything was back to normal. So, I repeated this test twice with the same results.

I tried this with my girlfriends BMW 335i and got expected results. RPM is limited to about 1500 and you can floor it indefinitely without that changing. Sounds like an overlooked use case on the Sky. Admittedly it's an odd test case, but not if you're stuck in the mud, so it should have been worked out.

Anyone have any idea why our cars, or at least my car, would behave this way? Unlikely, but possible that both my front sensors are bad? Or, maybe this has been addressed in an update and I need to perform service programming on the module.

My thought is that the system is designed to keep you stable while moving, and the possibility that you are trying to get un-stuck was overlooked. I have never tested mine under those conditions, so I can't say what it does. You could try a similar test while moving to see if the system activaes without errors.

My thought is that the sensors are OK because I think you would get ABS faults if they were bad.

That's been my experience. With the front tires stopped and the rears spinning, the TC system thinks there is a problem with the front sensors since they are receiving no data (or what they think is no data). If you had a bad wheel sensor, you'd be getting ABS errors too.

Thanks guys! It makes sense that we're not setup to get unstuck. By contrast, the BMW's literature specifically talks about their traction control helping you get unstuck. Just a different target audience between the two cars.

Robotech, is you're car's name a nod to Max Sterling? I liked Milia Sterling (Fallyna Jenius). Awesome long green hair! Of course Dana Sterling rocked the second show!

Your prior car V.A.L., Valkyrie? Those were supercool in guardian mode.

That is exactly what it is. The VAL was something else...to which I cannot remember what the acronym stood for...but I think I'm going to revise it to represent Valkyrie as I do like that...and Guardian was, by far, my favorite "mode" of the Veritech fighter.

My plate kind of reflects it too. Remember after Rick made Admiral, Max took over Skull squadron. Note Max is blue? My Sportster just got her tank painted red and is named...you guessed it...Mirya (Milia was her name in Macross, the original Japanese TV show used for 1st Gen Robotech).

I expect so, unless you turn it off.

I did get this error when I was dyno tuning my car. As soon as i started driving the CEL cleared.
