How to Fix B1314 Battery Saver Relay Coil Circuit Open

Introduction

If you’re experiencing issues with your car battery, it could be due to a faulty battery saver relay coil circuit. The B1314 error code indicates that there is an open circuit in the battery saver relay coil, which can cause your battery to drain quickly. In this article, we’ll provide you with step-by-step instructions on how to fix the B1314 error code and get your car back on the road.

Step 1: Check the Battery

Before you start troubleshooting the B1314 error code, it’s important to check the battery. Make sure that the battery is fully charged and in good condition. If the battery is not in good condition, it may not be able to hold a charge, which can cause the B1314 error code to appear.

Step 2: Check the Wiring

The next step is to check the wiring. Look for any loose or damaged wires that may be causing the open circuit. If you find any loose or damaged wires, repair or replace them as necessary.

Step 3: Check the Battery Saver Relay

If the wiring is in good condition, the next step is to check the battery saver relay. The battery saver relay is responsible for controlling the power to the battery. If the relay is faulty, it can cause the B1314 error code to appear.

To check the battery saver relay, you’ll need a multimeter. Set the multimeter to the resistance setting and touch the probes to the relay terminals. If the multimeter reads infinite resistance, the relay is faulty and needs to be replaced.

Step 4: Replace the Battery Saver Relay

If the battery saver relay is faulty, you’ll need to replace it. To replace the relay, follow these steps:

1. Disconnect the negative battery cable.
2. Locate the battery saver relay. It’s usually located in the fuse box under the hood.
3. Remove the old relay by pulling it straight out.
4. Insert the new relay by pushing it straight in.
5. Reconnect the negative battery cable.

Step 5: Test the System

After replacing the battery saver relay, it’s important to test the system to make sure that the B1314 error code is no longer appearing. Start the car and let it run for a few minutes. Check the battery voltage to make sure that it’s holding a charge. If everything looks good, you’ve successfully fixed the B1314 error code.

Conclusion

Fixing the B1314 error code is a relatively simple process that can be done at home with a few basic tools. By following the steps outlined in this article, you can get your car back on the road and avoid costly repairs at the mechanic.
