B1384 – OBD-II DTC

OBD-II DTC B1384 – Oil Level Lamp Circuit Failure

DTC B1384 meaning

DTC B1384 refers to a fault in the oil level lamp circuit. This diagnostic trouble code indicates that the vehicle’s onboard diagnostic system has detected an issue with the circuit responsible for monitoring the oil level lamp, which is crucial for alerting the driver about low oil levels. The oil level lamp is typically part of the vehicle’s instrument cluster and is designed to illuminate when the oil level is below the recommended threshold.

DTC B1384 symptoms

Common symptoms associated with DTC B1384 may include:

• The oil level warning light remains illuminated on the dashboard.
• The oil level warning light does not illuminate when the ignition is turned on.
• Erratic behavior of the oil level warning light.
• Possible engine performance issues due to low oil levels.

DTC B1384 causes

Several factors can lead to the occurrence of DTC B1384, including:

• A faulty oil level sensor.
• Wiring issues, such as damaged or corroded wires in the oil level lamp circuit.
• Faulty connectors that may not provide a proper connection.
• Issues with the vehicle’s engine control module (ECM) or body control module (BCM).
• Low oil levels or oil contamination affecting sensor readings.

DTC B1384 seriousness

DTC B1384 is considered a moderate issue. While it may not immediately affect the drivability of the vehicle, it can lead to serious engine damage if the oil level is indeed low and goes unnoticed. Ignoring this code can result in inadequate lubrication, overheating, and ultimately engine failure.

How to diagnose DTC B1384

To diagnose DTC B1384, follow these steps:

1. Use an OBD-II scanner to confirm the presence of the B1384 code.
2. Inspect the oil level to ensure it is within the recommended range.
3. Check the oil level sensor for proper operation and any visible damage.
4. Examine the wiring and connectors associated with the oil level lamp circuit for signs of wear or corrosion.
5. Test the continuity of the circuit using a multimeter.
6. Check the ECM or BCM for any related fault codes that may provide additional context.

How to fix DTC B1384 step-by-step instructions

To fix DTC B1384, follow these step-by-step instructions:

1. Confirm the oil level is adequate and top off if necessary.
2. Replace the oil level sensor if it is found to be faulty.
3. Repair or replace any damaged wiring or connectors in the oil level lamp circuit.
4. Clear any corrosion from connectors and ensure a secure fit.
5. Recheck the circuit for continuity and proper voltage.
6. Reconnect the battery and perform a test drive to see if the code reappears.

How to erase DTC B1384

To erase DTC B1384, follow these steps:

1. Connect an OBD-II scanner to the vehicle’s diagnostic port.
2. Turn on the ignition without starting the engine.
3. Navigate to the “Erase Codes” or “Clear Codes” option on the scanner.
4. Confirm the action to clear the DTC from the system.
5. Disconnect the scanner and start the engine to verify that the code does not return.
