What are some of the reasons the wrench light will light up on a 2008 Lincoln MKZ?
I was looking at a 2008 Lincoln MKZ off Craigslist. 93,000 miles, no check
engine light on but the wrench light is on. I think the wrench light is an
indicator for the AWD/Transmission system? It drives straight as an arrow,
no pull at all when taking hands off the wheel. Accelerates fine, stops on a
dime. I read somewhere that putting in a new battery can cause the wrench
light to turn on as a false alarm, is that true? I tried running a code reader on
it. No codes came up at all, and the wrench light is just.. There.
