Test L: The Delayed Accessory Does Not Turn Off

PINPOINT TEST L: THE DELAYED ACCESSORY DOES NOT TURN OFF

Normal Operation
The delayed accessory relay, which is integral to the smart junction box (SJB), receives power at all times through circuit SDC04 (RD). When the ignition key is turned ON, the SJB activates the delayed accessory relay, which provides power to the LH front window switch (Expedition) through circuit CBP47 (GN/BU). 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 CBP41 (BU). The rear window circuits are powered by circuit CBP47 (GN/BU). The delayed accessory feature remains active for 10 minutes after the ignition key is turned OFF or until either front door is opened.

- DTC B1304 - Accessory delay relay coil circuit short to battery, short to ground on output.

This pinpoint test is intended to diagnose the following:
- Delayed accessory relay
- Wiring, terminals or connectors
- SJB
