Circuit Description

The solenoid relay is internal part of the EBCM. Battery voltage is supplied from terminals A and B for the relay switch at all times. When the ignition switch is turned ON, battery voltage from terminal A11 is supplied to the relay coil.

The EBCM will then ground the relay coil circuit to switch the relay on, this supplies the solenoids and motor with battery voltage. The relay will remain in the on position as long as the ignition switch remains on, or a DTC set which turns off the relay.
