July 1: So it begins. Don't worry, this is not in the correct legal jurisdiction!

Self-Shut Relay

If the TCM self-shut relay is not activated due to a malfunction even when the ignition switch is ON, the transmission falls in a no-control state because it cannot supply power to each solenoid. Even in this case, TCM makes the AT OIL TEMP light flash via the CAN communication to alert the driver to the malfunction.
