Transaxle Control Module (TCM)
WARNING: This page is about a different variant/trim than selected.
NOTE:
The TCM is a part of the electronically controlled CVT assembly and cannot be repaired as a separate component. Refer to AUTOMATIC TRANSAXLE/TRANSMISSION EXTERNAL CONTROLS
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.
