The accessory delay relay receives voltage at all times from the Smart Junction Box (SJB). The SJB controls the coil side ground of the accessory delay relay and activates the accessory delay relay when the ignition switch is in the ON position. The accessory delay relay remains active for an additional 10 minutes when the ignition switch is in the OFF position or until the driver door is opened. The accessory delay relay provides voltage to the door lock switches, power windows and roof opening panel (if equipped).
