In the vehicle, the electrical accessories including the fuel injection system,
Horns, starter, and fog lamps employs a relay to send the electrical signal to the concerned component. Relays work on a principle by which a low current circuit is used to switch on and off a high current circuit. In other words, when a relay is faulty the related component will not operate as required. All relays are arranged in the engine bay and compartment as well as interior fuse/relay boxes; the engine compartment fuse and relay panel is on right side of the engine compartment; the front interior fuse/relay box is behind the left end cap of the instrument panel and includes a fuse and relay card located on the back cover.
