Normal Operation
The battery junction box (BJB) fuse 1 (25A) supplies voltage to the smart junction box (SJB) fuse 4 (10A) on circuit 37 (YE). The accessory delay relay receives voltage from the SJB fuse 4 (10A) for the coil side and receives voltage from the BJB fuse 19 (40A) on circuit 785 (BK/LG) for the switch side. 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 drivers door is opened. The SJB fuse 15 (30A) provides voltage to circuit 170 (RD/LB) for the accessory delay components.

Possible Causes
- Circuit 170 (RD/LB) short to voltage
- Accessory delay relay
- SJB
