SL/R231: Is there a test for the windshield wiring?


Are there just heaters or other stuff too?
I have a Xentry setup.








But, i’m going to bet that it would throw a code if any wiring issues were present. Scan the car right after installation of windshield.
I’m away from my shop so don’t have a copy of the WIS, which should have more info. But if you have XENTRY you probably have a copy of the WIS.
Good Luck
