Scion 90982-09021 Fuse, Mini

A fuse disconnects a circuit when a certain amount of current flows through it and can be used for safeguard of components and wires and all other forms of wiring from high amounts of current, usually as a result of a fault ,more commonly a short circuit. The primary fuses are arranged in the fuse compartment that is accessed by a panel in the stowage tray in front of the driver's seat; additionally, there are secondary fuses in the second fuse compartment positioned in the engine compartment adjacent to the battery. To gain access to the fuses pull the fusebox lid from the rear of the storage tray forward or remove off the lid of the fuse box on the engine compartment. In case of a blown fuse you will see that the wire of the fuse is either melted or broken. When undertaking the removal of the fuses, it is necessary to turn off the corresponding circuit; preferably, the battery should also be disconnected. An additional action that could be taken if using the thin-nosed pliers is to remove the fuse from wherever it was finding its way. Use a correct fuse rating where a fuse has blown, and never replace it with the wrong or higher one or make temporary connections, as this can result to more severe damage or occasion a fire. The fuses are colour-coded, and have specific ratings noted on the casing while large 'midi' fuses located in the engine compartment fuse box are ideal indications of serious wiring problems if blown. Relays are used for a number of reasons such as change over heavy currents at a remote location, when a device is required to receive many control signals, relay with timers. The relays are in the under-facia fusebox and the engine compartment fusebox, although some models have a relay box additionally. When a circuit which is controlled by a relay gets a fault, switching should provide an audible tone of 'click' if the relay is operational; if the relay do not produce the tone then the relay may not be receiving power or simply a faulty relay. Functional testing can be done by substituting with a know to be good unit, however, care must be taken since some relays look alike but are differ in functionality. To take out a relay, the circuit has to be off, after that, one pulls it out from the slot and plugs it in as a normal practice would prescribe.

Fusible links are used in circuits that are not ordinarily fused or that carry high current.

Yes, additional fuses may be present in smaller boxes near the radiator or in the relay box at the right fender area for certain models like the Solara and Avalon.

A fuse is blown if power is present on one side of the fuse but not the other, or it can be confirmed by visually inspecting it; when a fuse blows, the element between the terminals melts.

Always check the fuse first. The best way to check the fuses is with a test light to check for power at the exposed terminal tips of each fuse.

A wire-type fusible link, installed in the harness between the battery and the fuse/relay blocks, protects the entire chassis electrical system and is located near the positive battery terminal.

If you have to replace a blown fusible link, make sure to replace it with one of the same specification. If the replacement fusible link blows in the same circuit, troubleshoot the circuit in which the fusible link melted before installing another fusible link.

If an electrical component fails, always check the fuse first. The best way to check fuses is with a test light. Check for power at the exposed terminal tips of each fuse. If power is present on one side of the fuse but not the other, the fuse is blown. A blown fuse can also be identified visually; when a fuse blows, the element between the terminals burns.

Miniaturized fuses with a blade terminal design are employed in the fuse boxes, allowing for fingertip removal and replacement.
