DTC P0607: Control Module Performance: General Description

TCM is activated by power supply. Signals from several sensors, such as ATFS and APS, is inputted to TCM. Comparing inputted signals with control LOGIC saved at micro controller and EEPROM, TCM controls Transmission as actuating solenoids. To guarantee accurate control, TCM performs SELF TEST, DIAGNOSIS of several sensors and actuators. And if serious trouble which affects vehicle performance occurs, TCM sets DTCs. At certain cases, TCM inhibits shifting in order to prevent dangerous situation due to incorrect control.
