As a Ford Ranger owner, understanding the functionality of your vehicle’s electrical system is crucial to ensure maximum performance and safety. One of the most important components of your vehicle’s electrical system is the fuse box, which is responsible for protecting your vehicle’s various electrical components from overloading or short circuiting. In this article, we will provide you with a comprehensive guide to understanding the Ford Ranger fuse diagram, including a detailed breakdown of each fuse and what it controls.
What is a Ford Ranger Fuse Box?
The Ford Ranger fuse box is a critical component of your vehicle’s electrical system, which is located underneath the dashboard on the driver’s side. It houses a collection of fuses, each of which is designated to protect a specific electrical component in your vehicle from damage caused by power surges or short circuits. To access the Ford Ranger fuse box, you will need to remove the dashboard’s cover panel, which is secured with a series of screws and clips.
What are Fuses and How Do They Work?
Fuses are essentially electrical safety devices that are designed to protect your vehicle’s electrical components from damage caused by power surges or short circuits. Each fuse is designed to break the circuit when it detects an excessive surge of power, which helps to prevent damage to the associated electrical component. Once the fuse is blown, it must be replaced with a new fuse of the same amperage rating to restore the circuit.
How to Read a Ford Ranger Fuse Diagram?
The Ford Ranger fuse diagram is a helpful reference tool that allows you to quickly and easily identify each fuse and its corresponding electrical component. The diagram is typically printed on the underside of the fuse box cover panel and includes a listing of all the fuses, their amperage ratings and their corresponding electrical components. To read the Ford Ranger fuse diagram, locate the specific fuse in question and cross-reference it with the diagram to determine which electrical component it controls.
Ford Ranger Fuse Diagram: A Detailed Breakdown
Now that you have a basic understanding of what the Ford Ranger fuse diagram is and how it works, let’s take a closer look at each fuse and what it controls.
| Fuse No. | Amperage Rating | Electrical Component |
|---|---|---|
| F1.1 | 10A | Instrument Cluster |
| F1.2 | 10A | PCM Keep Alive Memory, Cluster, Radio Memory, Climate Control Module, and Antilock Brake System (ABS) |
| F1.3 | 20A | Stop Lamp Switch (Lamps), Turn/Hazard Flasher, Powertrain Control Module (PCM), Rear Anti-Lock Brake System (RABS) Module |
| F1.4 | 10A | Accessory Delay Relay, Power Mirrors, Power Door Locks, Reverse Lamps, DRL, Rear Defrost Relay, Fog Lamps, Trailer Tow Connector |
F1.1 (10A): Instrument Cluster
The F1.1 fuse controls the Instrument Cluster, which displays your vehicle’s vital stats such as speed, engine RPM, fuel level, and engine temperature. If this fuse is blown or faulty, your Instrument Cluster will not function properly, which may result in inaccurate readings or no readings at all.
F1.2 (10A): PCM Keep Alive Memory, Cluster, Radio Memory, Climate Control Module, and ABS
The F1.2 fuse controls the Powertrain Control Module (PCM) Keep Alive Memory, which allows your vehicle’s computer to store critical information such as idle speed, fuel trim, and transmission shift points. This fuse also controls the Radio Memory, Climate Control Module, and Antilock Brake System (ABS), which are essential electrical components of your vehicle.
F1.3 (20A): Stop Lamp Switch, Turn/Hazard Flasher, PCM, and RABS Module
The F1.3 fuse controls several essential electrical components of your vehicle, including the Stop Lamp Switch (Lamps), Turn/Hazard Flasher, Powertrain Control Module (PCM), and Rear Anti-Lock Brake System (RABS) Module. If this fuse is blown, you may experience issues with your vehicle’s brakes, turn signals, or hazard lights.
F1.4 (10A): Accessory Delay Relay, Power Mirrors, Power Door Locks, Reverse Lamps, DRL, Rear Defrost Relay, Fog Lamps, Trailer Tow Connector
The F1.4 fuse controls several important electrical components of your vehicle, including the Accessory Delay Relay, Power Mirrors, Power Door Locks, Reverse Lamps, Daytime Running Lights (DRL), Rear Defrost Relay, Fog Lamps, and Trailer Tow Connector. If this fuse is faulty or blown, you may experience issues with any of these electrical components, which can be both frustrating and potentially dangerous.
