error code 520215

[Flying Dutchman]

My 2015 is throwing this code. The manual reads Exhaust valve solenoid-driver circuit grounded - driver circuit short to B+. So what does that mean exactly? Is there something I can check? Wiring, broken part? Sled seems to run fine.
I do have warranty but it's a pain dropping off at dealer, when I can repair the misc stuff myself. If there's more to it, I'll bring it in. Any insight is appreciated.

with an ohmmeter start checking the exhaust valve solenoid and see if there is cont to ground with it unplugged and then backwards toward the ECU- backwards one side of the connector might show ground ? General electrical trouble shooting here!!

Could be a shorted solenoid also??

FWIW, I took it to the dealer who replaced the solenoid. No other codes present when they ran it through their tester. Covered under warranty.
