Check the interior electrical panel first and confirm each slot against its labeled function before replacing any protective element. Use the exact amperage rating printed on the component to avoid overheating wires or damaging control modules.
This compact pickup uses two main distribution points: one inside the cabin near the passenger side kick panel and another under the hood close to the battery. Low-current systems such as interior lighting, audio, and control switches are routed through the cabin panel, while high-load circuits like cooling fans and engine management are handled in the engine compartment.
Each position is marked with short codes such as “PCM,” “IGN,” or “ACC,” indicating powertrain control, ignition feed, and accessory circuits. Match these labels with the system that has stopped working, then inspect the metal strip inside the protective insert for visible breaks.
Keep spare blade-style inserts rated at 10A, 15A, 20A, and 30A available for quick replacement. Repeated failure signals a wiring short or faulty component, so trace the circuit path instead of replacing parts multiple times.

Locate the passenger-side kick panel and verify each circuit position using the printed legend before handling any protective insert.
The interior distribution unit is arranged in vertical columns with numbered slots tied to systems such as radio, instrument cluster, and interior lighting. Typical ratings range from 10A to 30A, with lower values assigned to control modules and higher values supporting motors and power outlets.
Under the hood, a separate power distribution center sits near the battery and contains larger cartridge-style links along with relays. These components manage high-current systems including fuel delivery, cooling fans, and engine control circuits.
Interior Panel Circuit Mapping
Each slot is labeled with short identifiers like “PCM,” “IGN,” “AUX,” or “WIPER.” These codes correspond to specific wiring paths. For example, “PCM” connects to the powertrain control module, while “IGN” feeds ignition-switched circuits across multiple subsystems.
Wiring colors provide additional reference points. Yellow or orange lines indicate constant battery feed, while green or pink wires often carry switched voltage. Ground paths are typically black and terminate at chassis نقاط behind the panel.
Engine Compartment Power Distribution
The engine bay unit uses relays marked with functions such as “FUEL PUMP,” “START,” and “A/C.” Each relay controls a high-load device by switching current through a low-power signal circuit. Check relay seating and terminal condition if a system fails without a blown insert.
Inspect the metal strip inside each protective element under good lighting. A break or burn mark confirms failure, while a solid strip indicates continuity through that circuit.
Reinstall all components firmly and ensure covers are secured, as loose connections or exposed terminals can cause intermittent electrical faults across multiple systems.
Passenger Compartment Fuse Panel Layout with Circuit Labels and Ratings
Verify each slot against the printed legend on the panel cover before removing any protective insert to avoid disconnecting the wrong circuit.
The interior power panel uses a grid layout with clearly marked abbreviations linked to specific systems. Typical label groups include:
- IGN SW – ignition switch feed
- AUX PWR – accessory outlet circuit
- WIPER – windshield wiper motor
- STOP LAMP – brake light circuit
- GEM – body control module functions
Each blade component carries a stamped amperage value that must match the original specification. Common ratings in this panel include:
- 10A for lighting and signal indicators
- 15A for audio and control electronics
- 20A for wiper and washer systems
- 30A for high-load cabin accessories
Reading Slot Positions
Slot numbering usually follows a top-left starting point and continues row by row. If the label sheet is missing, identify circuits by wire color codes such as orange for constant battery feed and light green for switched outputs.
Secure Installation and Contact Check
Press each insert fully into place until it sits level with the panel surface. Inspect terminals for corrosion or looseness, as poor contact can cause intermittent loss of power to multiple interior systems.
