The electrical circuits of the vehicle are protected by fuses, circuit breakers, and fusible links While the main fuse/relay panel and the IPDM E/R are situated in the engine compartment on the driver's side near the battery. The interior fuse/relay board is situated in the passenger compartment of your car near the driver side part of the dashboard while the fuse box diagram is written and attached at the rear part of the fuse box cover. Small, medium and large fuses are incorporated in the fuse blocks and these have blade terminal configuration; it may be noted that the medium and large fuses can be pulled with bare hands while, the small fuses have to be removed using pliers or a plastic fuse pulling tool. In case of a failed electrical component, the first thing to consider is the fuse; a test light should then be used to check power at terminal ends; a blown fuse can be ascertained on one side of fuse by absence of power or by appearance. When you replace broken fuses, you must use the right kind of fuses, wrong fuses will affect the protection of circuit. He should check if the cause of immediate blasting of the fuse is due to some other problem such as short circuit; if it is, that has to be solved before replacement of a fuse. Some circuits are protected by fusible links, especially those circuits that have a high current, reside in the fusible link box, which is soldered to the positive battery cable terminal; the scanning must be made before buying a new fusible link box if it is melted. Circuit breakers individually protect some circuits like the power windows, heated seats, and others; If it does not trigger a reset, it means it has overloaded and requires inspection. To perform basic checks on circuit breakers they can be pulled slightly out of their sockets to assess the battery voltage; if voltage is present on only one end the circuit breaker needs to be replaced; some circuit breakers need to be reactivated manually.
