Pinpoint Test K : The Delayed Accessory Is Inoperative: Notes

Refer to Power Windows , for schematic and connector information.

Normal Operation 

When the ignition is turned ON, the BCM activates the accessory delay relay, which provides power to LF power window through CBP32 (GN/VT)/CBP41 (BU) and the LH front window switch (Expedition) through circuit(s) CBP48 (GY/YE) and CBP47 (GN/BU) (Expedition only). For Navigator, delayed accessory power is provided to the LF and RF power window motors, RH front window switch and front window circuits in the LH front window switch through circuit CBP32 (GN/VT)/CBP41 (BU). The delayed accessory feature remains active for 10 minutes after the ignition is turned OFF or until either front door is opened.

• DTC B131A:14 (Delayed Accessory Power: Circuit Short To Ground or Open) - Sets when an open or short to ground is detected by the BCM on the relay control circuit.
• DTC B131A:12 (Delayed Accessory Power: Circuit Short To Battery) - Sets when a short to voltage is detected by the BCM on the relay control circuit.

This pinpoint test is intended to diagnose the following: 

• Circuit breaker
• Accessory delay relay
• Wiring, terminals or connectors
• BCM
