Check the interior panel under the dashboard on the driver side first, then inspect the engine bay unit near the battery to locate all circuit protection elements and relays.
Use the cover legend to match each slot with its function. Typical ratings include 10A for interior lighting, 15A for audio and accessory outlets, and 30A or higher for systems like radiator fan and power windows.
If a circuit stops working, inspect the metal strip inside each protective link. A break or burn mark indicates failure. Replace it with the same amperage value to prevent wiring damage.
For repeated issues, trace the wiring connected to the affected slot. Pay attention to door harnesses, under-dash routing, and areas near moving parts where insulation wear often leads to short circuits.
Panel scheme and circuit identification for EX version
Use the printed layout on the cover to align each slot with its circuit, then confirm the rating stamped on the component before pulling it out.
Interior panel handles cabin electronics such as dashboard lights, radio, and accessory sockets, while the engine compartment unit manages high-load systems like ignition, cooling fan, and ABS; this separation helps narrow down faults quickly when a specific system fails.
Trace circuits by wire color if labels are unclear; solid red wires usually indicate constant power, while striped variants lead to switched lines, allowing faster identification without full disassembly.
Practical check method
Turn off ignition, locate the correct panel, remove the element using a puller, inspect the metal bridge inside, replace with matching amperage, and verify system operation.
Locations of electrical panels and how to access them
Open the driver side lower dash area to reach the interior panel; it is positioned to the left of the steering column behind a small removable cover.
Pull the cover outward using the molded grip point, releasing the retaining clips with steady pressure to avoid cracking the plastic.
This interior unit contains low and mid load circuit protection for cabin systems such as lighting, radio, and accessory ports.
Next, locate the engine compartment unit near the battery; it sits inside a rectangular plastic housing with a sealed lid.
Press the locking tabs on both sides and lift the cover upward. If it feels stuck, move it slightly side to side instead of forcing it.
Inside this engine bay housing are high-current links and relay modules controlling ignition, cooling fan, and braking systems.
Turn ignition off before accessing any panel, and disconnect the negative battery cable when working near main power distribution to reduce risk of short circuits.
