B131A FORD Meaning

The Accessory Delay Relay is located in the Body Control Module (BCM). When the ignition is turned ON, the BCM activates the accessory delay relay by grounding the relay coil. When the ignition is turned to the OFF position, the BCM continues to ground the accessory delay relay coil for approximately 10 minutes, or until a front door is opened. When the accessory delay relay is active, it supplies voltage to the power window system. The OBDII sets when the BCM senses an open, short to voltage or short to ground on the accessory delay relay control circuit.
