B1375: Oil Change Lamp Circuit Open

Definition

The OBD2 code B1375 indicates that there is an open circuit in the oil change lamp system, meaning the system responsible for indicating when an oil change is needed is not functioning properly due to a break in the circuit

Common causes

Faulty oil change lamp
Open circuit in wiring
Poor connection or corroded terminals
Faulty instrument cluster
Malfunctioning body control module (BCM)
Blown fuse related to the oil change lamp circuit

Common misdiagnoses

Faulty oil change reminder system
Defective oil pressure sensor
Malfunctioning engine control module (ECM)
Wiring issues or shorts in the circuit
Faulty oil level sensor
Incorrect oil change interval settings
Battery or electrical system problems

Troubleshooting steps

1. Check the Owner's Manual

Refer to your vehicle's owner manual for specific information about the oil change lamp system and its components
2. Inspect the Wiring and Connectors
3. Visually inspect the wiring harness and connectors associated with the oil change lamp circuit. Look for any signs of damage, corrosion, or loose connections
4. Ensure that all connectors are securely plugged in
5. Test the Oil Change Lamp
6. Check if the oil change lamp itself is functioning properly. If the bulb is burnt out or the LED is damaged, it may cause the circuit to register as open
7. Check the Oil Change Reset Procedure
8. Some vehicles require a specific procedure to reset the oil change light after an oil change. Ensure that this procedure has been followed correctly
9. Inspect the Oil Change Sensor
10. If your vehicle is equipped with an oil change sensor, check its operation. A faulty sensor can cause the circuit to register as open
11. Scan for Additional Codes
12. Use an OBD-II scanner to check for any additional trouble codes that may provide more context or indicate related issues
13. Check the Fuses
14. Inspect the fuses related to the oil change lamp circuit. A blown fuse can interrupt the circuit and cause the code to trigger
15. Test the Circuit
16. Use a multimeter to test the continuity of the circuit. Check for voltage at the oil change lamp connector and ensure that there are no breaks in the wiring
17. Clear the Code
18. After performing any repairs or inspections, clear the code using an OBD-II scanner and see if it returns after a short drive
19. Consult a Professional
20. If the issue persists after performing these steps, it may be best to consult a professional mechanic or technician who can perform more in-depth diagnostics. By following these steps, you should be able to identify and resolve the issue related to the B1375 code
