Acura 38211-SM4-003 Block Fuse (30A)

The electrical circuits of the vehicle are protected by a combination of fuses and circuit breakers, with two fuse blocks located under the instrument panel and on the right side of the engine compartment, or three blocks on models equipped with ABS. Each fuse is designed to protect a specific circuit, and the circuits are identified on the fuse panel. Miniaturized fuses with blade terminal design allow for easy fingertip removal and replacement. If an electrical component fails, checking the fuse first is essential; turning the ignition key to the On position and probing each exposed terminal with a test light will indicate if the fuse is good or blown. Blown fuses can be visually identified through their clear plastic body, and it's important to replace them with the correct type, as using fuses of different ratings is not recommended. If a replacement fuse fails immediately, the underlying issue, often a short circuit due to damaged wiring, should be addressed before further replacements. All models feature a main fuse, either 80A or 100A, which protects all circuits from the battery; if overloaded, this fuse will blow to prevent damage to the wiring harness. The main fuse, located in the engine compartment fuse block, resembles standard fuses and should be replaced with an equivalent unit, ensuring that the amperage rating matches the original.
