Did a lift and upgraded UCAs last week on our 2020 ORP.

In the process I tore an ABS wire (I know... I know...) which I've since replaced. The ABS flashing lights cleared, but I was left with an issue with the Pre-Collision warning system nagging me to go to the dealer.

Checked the code, and it is C1290 - Malfunction in Zero Point Calibration. This is related to the centered steering-wheel angle. I can see that being a separate issue based on my first test drive with the UCAs being set slightly differently (and steering angle was off). Again, since corrected, and alignment has been done, but code remains.

Shouldn't be a problem, right? Just do the trick with the DLC-3 (OBD) connector by jumping pins 4 and 12. But it didn't work...

Did a contortionist act, and looked very carefully at the front of the connector. Hmmm, it didn't look like the connector at position 12 was occupied. Pulled the connector off, and my suspicions were confirmed. Looks like on 2020s we get pins 4,5,6,7,14, and 16. So ground (4,5), Can Bus (6,14), K-line (7) and 12v (16). No more TS (or TC) lines.

Looks like this may require TechStream to do a ZPC. Any advice or suggestions are welcome. Anybody know if the TS line might be available someplace else? I'm having a tough time running down the 2020 schematics.
