Safety is our priority, so keep your tools handy and your battery disconnected when necessary.
Understanding the 2013 ford focus starter relay and Its Function
A relay is essentially a remote-controlled switch that allows a low-current circuit to control a high-current circuit. When you turn your key to the “Start” position, you aren’t sending the full power of the battery to the starter motor through the ignition switch. Instead, you are sending a small signal to the 2013 ford focus starter relay.
Once this relay receives that small signal, an internal electromagnet pulls a set of heavy-duty contacts together. This completes the path for the heavy electrical current to flow directly from your battery to the starter solenoid. This design protects your ignition switch from melting under the massive electrical load required to turn over the engine.
In the MK3 Ford Focus (2012-2018), the electrical system is managed by several modules, including the Body Control Module (BCM). If the relay fails, the “handshake” between your key and the starter motor is broken. You might see your dashboard lights come on, but the engine will remain completely unresponsive.
Where to Find the Starter Relay in Your Focus
Locating the 2013 ford focus starter relay is the first hurdle for most owners. Unlike older cars where relays were scattered, Ford centralized most of these in the Engine Compartment Fuse Box. This box is located on the driver’s side of the engine bay, right next to the battery box.
Opening the Junction Box
To access the relays, you must remove the plastic cover of the fuse box. There are typically two plastic tabs on the side that you need to squeeze or lift. Once the cover is off, flip it over; Ford usually prints a diagram on the underside to help you identify the components.
Identifying Relay R1
In the 2013 model year, the starter relay is almost always labeled as R1. It is a small, square black or gray box. It sits among several other similar relays that control the cooling fans and the powertrain control module. Ensure the area is clean of debris before pulling the relay to prevent dirt from falling into the terminal slots.
Symptoms of a Failing Starter Relay
How do you know if the 2013 ford focus starter relay is actually the problem? Relays rarely fail gracefully; they usually work perfectly until the moment they don’t. However, there are a few “telltale” signs that point specifically to this component rather than the starter motor itself.
- The Single Click: If you hear one sharp “click” when you turn the key, but the engine doesn’t crank, the relay might be engaging, but the internal contacts are burnt.
- Rapid Clicking: This often signals low voltage. While it could be the relay, it is more likely a weak battery or poor ground connection.
- Total Silence: If there is no sound at all, the relay coil might be dead, or it isn’t receiving the trigger signal from the ignition.
- Intermittent Starting: If the car starts fine one day and refuses the next, the relay contacts are likely pitted and making poor electrical contact.
Step-by-Step Guide to Testing the Relay
Before you go out and buy a new 2013 ford focus starter relay, you should test the one you have. There are two main ways to do this: the “Quick Swap” method and the “Multimeter” method. Both are effective, but one is much faster if you are stuck in a parking lot.
The Quick Swap Method
The easiest way to test a relay is to find another identical relay in the fuse box that isn’t essential for starting the car. For example, the horn relay or the rear defroster relay is often the same part number. Swap the suspected bad relay with a known good one and try to start the car.
If the engine cranks immediately with the swapped relay, you have found your problem. This is a classic technician’s trick that requires zero tools. Just be sure to check the part numbers on the side of the relays to ensure they are electrically compatible.
Using a Multimeter for Accuracy
If you want to be 100% certain, use a digital multimeter set to the “Ohms” or “Continuity” setting. A healthy relay should show a specific resistance across the coil pins (usually pins 85 and 86). If the circuit is “Open” (reads OL), the internal coil is broken, and the relay is junk.
- Remove the relay from the fuse box.
- Identify the pins using the diagram on the side of the relay housing.
- Check for continuity between the high-current pins (30 and 87) while applying 12V power to the coil pins.
- If the switch doesn’t close when powered, the 2013 ford focus starter relay must be replaced.
Common Problems Beyond the Relay
Sometimes, you replace the relay and the car still won’t start. In the 2013 Ford Focus, there are a few “usual suspects” that mimic a bad relay. Because this generation of Focus uses a complex electrical architecture, you have to look at the bigger picture.
Corroded Ground Wires
Ford Focus models from this era are notorious for “bad grounds.” There is a main ground strap located underneath the air filter box that connects to the chassis. If this connection is corroded or paint is blocking the contact, the relay won’t have enough “pull” to engage the starter.
The Transmission Control Module (TCM)
This is a big one for 2013 owners. If your Focus has the dual-clutch automatic transmission (DPS6), a failing TCM can prevent the car from starting. The car needs to “know” it is in Park or Neutral to allow the starter circuit to complete. If the TCM is glitching, it won’t send the signal to the 2013 ford focus starter relay.
Battery Terminal Corrosion
Always check for that white, crusty powder on your battery terminals. This lead sulfate acts as an insulator, preventing the high amperage needed for starting from reaching the rest of the car. Clean them with a wire brush and a mixture of baking soda and water for a fresh connection.
How to Replace the Starter Relay Safely
Replacing the relay is a “plug-and-play” operation, but there are a few safety steps you should follow to avoid damaging the car’s sensitive electronics. Always work with the ignition in the OFF position and the key removed from the vehicle.
First, ensure you have the correct replacement part. While many relays look the same, they have different amperage ratings and internal resistor/diode configurations. Using the wrong relay can cause a voltage spike that damages the Powertrain Control Module (PCM).
Line up the pins of the new relay with the slots in the fuse box. They are keyed to only go in one way, so do not force it. Press it down firmly until it is flush with the other relays. Reinstall the fuse box cover, ensuring the seal is tight to keep out moisture and road salt.
Frequently Asked Questions About the 2013 Ford Focus Starter Relay
Can I bypass the starter relay in an emergency?
Technically, you can “jump” pins 30 and 87 in the fuse box with a heavy-gauge wire to engage the starter. However, this is dangerous and can cause sparks or accidental vehicle movement if the car is in gear. Only attempt this if you are an experienced mechanic in a dire situation.
How much does a replacement relay cost?
An OEM Ford starter relay typically costs between $15 and $25 at a dealership. You can find aftermarket versions at local auto parts stores for around $10 to $12. Given the low cost, it is often worth keeping a spare relay in your glovebox.
Why does my relay keep clicking but the car won’t start?
Clicking usually means the relay is trying to work but there isn’t enough “juice” to keep the contacts closed. This is almost always a sign of a dead battery or a loose battery cable rather than a faulty relay itself. Always test your battery voltage first.
Is the starter relay the same as the starter solenoid?
No, they are different parts. The relay is in the fuse box and handles moderate current. The solenoid is attached directly to the starter motor and handles the massive current required to actually turn the engine. The relay triggers the solenoid.
Final Thoughts for the DIY Mechanic
Troubleshooting the 2013 ford focus starter relay is an empowering project that can save you significant money and stress. By following a logical path—checking the battery, inspecting the relay, and verifying grounds—you can solve most no-start issues in your own driveway. Most of the time, these cars just need a little electrical maintenance to stay reliable.
Remember that the 2013 Focus is a “smart” car; its computers are constantly monitoring these circuits. If you find yourself stuck, don’t be afraid to use an OBD-II scanner to look for “P” codes related to the starter circuit. These codes can often point you directly to a wiring fault or a module issue that a visual inspection might miss.
Stay safe, keep your connections clean, and don’t let a small electrical component keep you off the road. With the right knowledge and a few simple tools, you are more than capable of keeping your Focus running strong for years to come. Happy wrenching!
