No power to OBD port

[Vic Sorlie]

2007 Buick Rendezvous, CEL came on after oil change. Plugged in my scanner to read code and it would not come on. Initially thought my scanner No Workee, but went to local O’Reilly store to get code read and their scanner wouldn’t fire up either. So the OBD port isn’t getting power. Looked in vehicle’s Owners Manual for fuse location but nothing is named in the diagram. Suggestions?

Usually referred to in the service manuals at DLC. But usually sharing some fuse in the engine bay, usually whatever goes to the “accessory” ports, used to go by cigarette lighter ports, but since they handicapped the amperage…

You were absolutely right. Took a look a couple of other YouTube videos, then armed myself with a small assortment of fuses and tester from O’Reilly. Found my prize in the underhood junction box – fuse #32 (20 amp) on this car. Replaced fuse, fired up scanner and cleared CEL. Thanks.
