Monitor Description
While the ECM is in operation, when the ignition switch is turned off, the ECM sends a command signal to turn off the main relay. This DTC is stored if the main relay is not turned off (+B voltage to ECM is not cut off) for longer than the specified period of time even if the command signal to turn off the main relay is sent from the ECM.
