Code B1314 Description
The B1314 diagnostic trouble code indicates that there is an open circuit in the battery saver relay coil circuit. The battery saver relay is responsible for controlling the power supply to various electrical components in the vehicle, such as interior lighting, power windows, and radio, when the ignition is turned off. An open circuit in this relay coil can prevent the relay from functioning properly, leading to issues with these electrical systems.
Common Causes of B1314
- Faulty battery saver relay
- Loose or damaged connections in the relay coil circuit
- Corrosion in the relay coil circuit
- Damaged wiring harnesses
Symptoms of B1314
- Dimming or flickering interior lights
- Malfunctioning power windows
- Radio not turning off when the ignition is switched off
- Drained battery leading to difficulty starting the vehicle
How to Fix B1314
- Begin by diagnosing the cause of the open circuit in the battery saver relay coil circuit using a multimeter to test the relay and wiring connections.
- Replace the faulty battery saver relay if it is determined to be the cause of the issue.
- Repair or replace any damaged wiring harnesses or connections in the relay coil circuit.
- Clear the diagnostic trouble codes from the vehicle's computer using a scan tool.
- Test the vehicle to ensure that the battery saver system is functioning properly and that the code does not return.
Cost to Fix B1314
The cost of repairing a B1314 code can vary depending on the specific cause of the issue and the labor rates at the repair facility. In general, replacing a faulty battery saver relay and repairing any damaged wiring harnesses can cost between $100 and $300 in parts and labor. It's important to factor in diagnostic time and potential additional repairs if other issues are discovered during the diagnosis process. Labor rates can vary between $80 and $150 per hour, so it's recommended to check with local repair shops for a more accurate estimate.

Frequently Asked Questions about B1314 Code
1. What does the OBDII code B1314 indicate?
The B1314 code signifies that there is an open circuit in the battery saver relay coil, which can affect the vehicle's ability to conserve battery power when the vehicle is off.
2. What are common symptoms of the B1314 code?
Symptoms may include the interior lights staying on longer than usual after the vehicle is turned off, increased battery drain, or the battery dying more quickly than expected.
3. What can cause the B1314 code to be triggered in a vehicle?
Potential causes include a faulty battery saver relay, damaged wiring in the relay circuit, or poor connections within the relay circuit.
4. How can I diagnose the B1314 code?
Diagnosis should start with a visual inspection of the battery saver relay and its circuitry for any obvious signs of damage or disconnection. Using a multimeter to check for continuity in the relay coil circuit can also help identify an open circuit.
5. What steps should be taken to repair a B1314 code?
Repair steps may include replacing the battery saver relay if it is found to be faulty, repairing any damaged wires or connectors in the relay circuit, and ensuring all connections are secure.
6. Is it safe to drive with the B1314 code?
While it may be safe to drive for a short period, doing so could result in a dead battery or reduced functionality of electrical components, which can eventually lead to more serious issues.
7. Does the B1314 code affect the vehicle's overall electrical system?
Yes, an open circuit in the battery saver relay can impact the electrical system by failing to properly manage power distribution when the vehicle is turned off, potentially leading to excessive battery drain.
8. How urgent is it to address a B1314 code?
It is moderately urgent to address this issue as it can lead to a drained battery and potential inconvenience, especially if the vehicle fails to start due to a dead battery.
9. Can a B1314 code clear itself if the underlying issue is resolved?
Yes, once the issue causing the open circuit is fixed, the code should clear. However, it may be necessary to use an OBDII scanner to reset the system and clear the code manually.
10. What tools are necessary to diagnose and repair a B1314 code?
Tools required may include a multimeter to test for continuity and voltage, a scanner to read and clear OBDII codes, and basic hand tools to access and replace the relay or repair wiring.
