Conditions for Running the DTC

WARNING: This page is about a different car, the 2015 Buick LaCrosse. However, it is still accessible from the selected car via links, so may be relevant.

The power steering control module runs the program to detect an internal fault when power up is commanded. The only requirements are voltage and ground. This program runs even if the voltage is out of the valid operating range.
