Diagnostic Method
Either of the following is detected:
- When the ignition switch is on (READY): The solenoid power supply voltage is less than 3.5 V, when the IG1 terminal voltage is 9.54 V or more and operation of the main relay is requested.
- When the ignition switch is off: The solenoid power supply voltage is less than 3.5 V, when operation of the main relay is requested.
