Where is the fuse for code reader plug?

The fuse for the code reader plug, commonly referred to as the OBD-II connector, is typically located in the vehicle's fuse box. This fuse box can usually be found under the dashboard on the driver's side or in the engine compartment, depending on the vehicle make and model. To identify the specific fuse for the code reader plug, consult the vehicle's owner’s manual, which often includes a diagram of the fuse box and the corresponding fuse functions. If the fuse is blown, replacing it should restore power to the OBD-II connector.
