Transmission Control Switch (TCS) Test
WARNING: This page does not describe the selected car, but rather 25 other vehicles, including the 2013 Lincoln Navigator, 2013 Lincoln MKZ, 2013 Lincoln MKX, 2013 Lincoln MKT, and 2013 Lincoln MKS. However, it is still accessible from the selected car via links, so may be relevant.
The TCS test checks the ability of the EEC system to detect a change of state in the TCS. The switch is briefly cycled on all vehicles equipped with a TCS input. This is done during a KOER on demand self-test.
