Self-Diagnostic System: Notes

TCM monitors transaxle operation along with input and output information. If TCM self-diagnostic system senses a transaxle or electrical circuit failure, a Diagnostic Trouble Code (DTC) will be stored in TCM memory. If malfunction goes away after DTC is stored in TCM memory, TCM will erase DTC after ignition has been cycled at least 40 times. DTCs are classified as either hard, one trip failure or intermittent codes.
