Code B1371 Lincoln Description
The B1371 code indicates a malfunction within the illuminated entry relay circuit in Lincoln vehicles. This system is designed to activate interior lights and exterior lights (such as courtesy lights) when the vehicle is unlocked or when a door is opened. The illuminated entry system enhances user convenience and safety, allowing for visibility when entering or exiting the vehicle, especially in low-light conditions.
Common Causes of B1371 Lincoln
- Faulty Relay: The illuminated entry relay itself may be defective, preventing it from functioning correctly.
- Wiring Issues: Damaged or corroded wiring in the circuit can disrupt the flow of electricity, leading to system failure.
- BCM Malfunction: The body control module may have faults that prevent it from sending the proper signals to the relay.
- Door Switch Failure: A malfunctioning door switch can fail to signal the BCM that a door has been opened, preventing light activation.
- Poor Ground Connection: A poor ground connection can lead to erratic behavior in the circuit, causing intermittent failures.
Symptoms of B1371 Lincoln
- Interior Lights Not Illuminating: The interior lights do not turn on when the doors are opened or when the vehicle is unlocked.
- Exterior Courtesy Lights Malfunction: The exterior lights fail to activate when the vehicle is approached or when doors are opened.
- Delayed Light Activation: There may be a delay in the lights turning on or off, indicating a potential relay issue.
- Inconsistent Operation: The illuminated entry system works intermittently, sometimes functioning correctly and other times failing.
- Battery Drain: The vehicle's battery may drain faster than normal if the lights remain on due to a malfunctioning relay.
How to Fix B1371 Lincoln
- Diagnostic Scan: Begin with a diagnostic scan to confirm the B1371 code and check for any additional codes that may provide further insight into the issue.
- Visual Inspection: Conduct a thorough visual inspection of the wiring harness and connectors associated with the illuminated entry relay for signs of damage or corrosion.
- Relay Testing: Test the illuminated entry relay using a multimeter to ensure it is functioning correctly. Replace it if it is found to be defective.
- Check BCM Functionality: If the relay is functioning, further diagnose the body control module for faults or programming issues that may affect the illuminated entry system.
- Repair or Replace Components: Based on the findings, repair any damaged wiring or connectors, replace the BCM if necessary, and ensure all ground connections are secure.
Cost to Fix B1371 Lincoln
The typical repair costs for addressing a B1371 code can vary widely based on the specific diagnosis and repair needed.
