Transaxle Control Module (TCM)
WARNING: This page is about a different car, the 2011 Mercury Milan, 2011 Lincoln MKZ, 2011 Ford Fusion, 2010 Mercury Milan, and 2010 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
The TCM is a part of the electronically controlled CVT assembly and cannot be repaired as a separate component. Refer to the AUTOMATIC TRANSMISSION - AUTOMATIC TRANSAXLE/TRANSMISSION - ELECTRONICALLY CONTROLLED CONTINUOUSLY VARIABLE TRANSMISSION (ECVT) - FUSION, MILAN & MKZ (HYBRID)
for electronically controlled CVT repair procedures.
The microprocessor that controls operation of the electronically controlled CVT is called the TCM. The TCM receives a variety of CAN messages and hardwired signals from modules connected to the CAN. Based on information received, the TCM makes a decision on how to control the operation of the generator motor or the traction motor. In case of a concern, the TCM is able to detect and store the appropriate DTC. To retrieve DTCs from the TCM, carry out an on-demand and continuous memory self-test.
