The accessory delay relay is located in the smart junction box (SJB), and the relay coil receives battery voltage through circuit 294 (WH/LB) at all times. When the key is turned ON, the SJB activates the accessory delay relay by grounding the relay coil, and power is sent to all window control switches. When the key is turned OFF, the SJB continues to ground the accessory delay relay coil for approximately 10 minutes, or until a door is opened.
