Electronic Control System: Notes
WARNING: This page is about a different variant/trim than selected.
TCM monitors transaxle operation along with input and output information. If TCM self-diagnostic system senses a transaxle or electrical circuit failure, a 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 or intermittent codes.
