Find Your Subaru Starter Relay Location – Easy Guide

If you’re experiencing starting issues with your Subaru, it may be due to a faulty starter relay. Finding the relay is the first step in troubleshooting the problem. Fortunately, locating the starter relay in your Subaru vehicle is a relatively easy process and requires only a few simple steps.

The starter relay is typically located in the engine compartment, near the battery or fuse box. In some Subaru models, the relay may be located under the dashboard or near the steering column. Consult your vehicle’s owner manual for specific information on the exact location.

Understanding the Subaru Starting System

Before we dive into the details of locating and troubleshooting the starter relay in a Subaru, it’s important to have a basic understanding of the starting system’s components. The starting system is made up of four main parts: the starter motor, ignition switch, battery, and starter relay.

The starter motor is responsible for the actual cranking of the engine when the ignition switch is turned. It converts electrical energy from the battery into mechanical energy to turn the engine’s crankshaft.

The ignition switch is the component that sends an electrical signal to the starter motor when the key is turned. It also controls the power to other electrical components in the vehicle.

The battery provides the electrical energy needed to power the starter motor and other electrical components in the vehicle. Without a properly functioning battery, the starting system won’t work.

The starter relay is a critical part of the starting system, acting as a switch that allows current to flow from the battery to the starter motor when the ignition switch is turned. It’s often located in the engine compartment and is activated by the ignition switch.

Working together, these components allow the engine to start and run smoothly. Understanding how they function will help with troubleshooting any starting issues you may experience with your Subaru.

Common Subaru Starting Problems

Subaru vehicles are generally reliable, but like any car, they can experience starting problems. Some of the most common Subaru starting issues include:

1. Clicking sound when turning the key: This is a common sign of a weak battery or a problem with the starter relay.
2. Engine not cranking: If you turn the key and nothing happens, it could be a sign of a bad starter motor, electrical issue, or a faulty starter relay.
3. Intermittent starting issues: If your Subaru starts sometimes but not always, it could be a sign of a faulty starter relay or other electrical issues in the car.

If you are experiencing any of these starting problems, it’s important to diagnose and fix them as soon as possible to avoid being stranded with a car that won’t start.

How the Starter Relay Could be Involved

The starter relay is an essential component of the starting system in any Subaru vehicle. It receives signals from the ignition switch and sends power to the starter motor to turn the engine over. If the starter relay fails, the engine won’t start, and you may hear a clicking sound when turning the key. It’s a good idea to check the starter relay first if you experience any starting problems, as it’s a common point of failure.

Note: It’s important to ensure that you have ruled out other potential causes of starting problems before replacing the starter relay. For example, a bad battery or starter motor could cause similar symptoms, so it’s crucial to test these components before replacing the starter relay.

Troubleshooting Subaru Starting Issues

If you’re experiencing issues with your Subaru starting, there are a few things you can do to troubleshoot the problem. Before attempting any troubleshooting, be sure to take all necessary safety precautions, including wearing protective gear and carefully following all instructions.

Step 1: Check the Battery

The first step in troubleshooting any starting issue is to check the battery. Make sure the battery is fully charged and that all connections are clean and tight. If the battery is low or the connections are corroded, it can cause starting issues. If the battery is not the problem, move on to step 2.

Step 2: Check the Starter Motor

If the battery is not the issue, the next step is to check the starter motor. This requires a special tool called a starter motor tester, which can be purchased or rented from most auto parts stores. With the tester, you can check the motor’s amp draw and voltage to make sure it’s working properly. If the motor is not the problem, move on to step 3.

Step 3: Check the Starter Relay

The starter relay is another key component of the starting system that can cause issues if it’s faulty. To check the starter relay, you’ll need a multimeter to test for continuity. First, locate the relay (see section 1 for instructions on how to find it). Then, remove the relay and test it using the multimeter. If the relay is not functioning properly, it will need to be replaced.

Step 4: Check the Ignition Switch

If the battery, starter motor, and starter relay are all functioning properly, the next step is to check the ignition switch. The ignition switch sends a signal to the starter relay to engage the starter motor and start the engine. Use your multimeter to test for continuity and make sure the switch is working correctly. If the switch is faulty, it will need to be replaced.

By following these steps, you can troubleshoot most starting issues in your Subaru. However, if you’re still having issues after checking all of these components, it may be time to take your vehicle to a qualified mechanic for further diagnosis.

Subaru Starter Relay Location

Locating the starter relay in your Subaru is the first step in troubleshooting any starting issues you may encounter. The starter relay is a small component that acts as a switch, delivering power from the battery to the starter motor when the ignition is turned on.

The location of the starter relay can vary depending on your Subaru model. In most cases, you can find the relay in the main fuse box under the hood. The fuse box will have a plastic cover that can be removed to access the relays. Check your owner’s manual for specific information on the location of the starter relay in your Subaru model.

If you’re having trouble locating the starter relay, don’t hesitate to consult a professional mechanic.

Signs of a Faulty Subaru Starter Relay

As an essential component of the starting system, a faulty starter relay can have various effects on your Subaru’s performance. Here are some signs that could indicate a malfunctioning starter relay:

• The engine won’t start or cranks slowly.
• You hear a clicking sound when turning the key.
• The starter motor runs continuously even after releasing the ignition switch.
• You experience intermittent electrical issues, such as flickering headlights or dashboard lights.

If you notice any of these signs, you should inspect your Subaru’s starter relay and other starting system components as soon as possible.

Note: Keep in mind that some of these signs could also indicate other starting system issues or electrical problems, so it’s essential to diagnose the problem accurately before attempting any repairs or replacements.

Subaru Starter Relay Replacement

If you have determined that your Subaru’s starting problems are due to a faulty starter relay, replacing it is a relatively simple task that can be done at home with basic tools. Follow these steps to replace your Subaru starter relay:

1. Disconnect the negative battery cable to prevent electrical shock.
2. Locate the starter relay. Refer to the previous sections for detailed instructions on how to find it.
3. Remove the old relay by gently pulling it straight out of its connector. Some models may require using a small flathead screwdriver to release a locking tab before pulling the relay out.
4. Insert the new relay into the connector, making sure it is seated firmly and correctly oriented. Some relays may have a locking tab that needs to be engaged.
5. Reconnect the negative battery cable.
6. Try starting the vehicle to confirm that the new relay has solved the starting problem.

Note: If you are unsure about performing this task or feel uncomfortable working with electrical components, it is recommended that you seek assistance from a certified mechanic.
