B1380 — Oil Change Reset Button Circuit Failure #

Note: The code description may vary depending on the vehicle manufacturer.

• Oil Service Reset Switch Circuit Error (Ford)
• Oil Life Reset Button Circuit Malfunction (GM/Chevrolet)
• Maintenance Reset Switch Circuit Fault (Toyota)

Summary of DTC B1380 #

The B1380 code refers to a detected malfunction in the oil change reset button circuit, which is part of the vehicle’s instrument cluster or body control module. This circuit allows the driver to reset the maintenance reminder after performing an oil change. When the control module (often called the Body Control Module or BCM) identifies an abnormal voltage, open, or short in the reset circuit, it stores this code. While not directly related to engine performance, this fault can prevent accurate maintenance tracking and warning light resets. The code may be accompanied by a warning message or a persistent maintenance reminder on your dashboard.

Common Symptoms for DTC B1380 #

When B1380 is triggered, the symptoms are usually limited to the vehicle’s maintenance reminder system. However, ignoring these can result in confusion over when service is due. Typical symptoms include:

• Oil change or maintenance light remains on after a service
• Unable to reset the maintenance reminder using the dashboard button
• Warning message or “reset failed” prompt on the instrument display
• Intermittent or non-functional reset button
• No audible confirmation when attempting to reset

Most Likely Causes for B1380 #

The B1380 code can be set for several reasons, most often related to electrical faults or switch malfunction. Here are the most common causes, ranked by likelihood:

1. Faulty oil change reset button (worn contacts or physical damage)
2. Open or short circuit in the button wiring or connector
3. Corroded or loose electrical connector at the instrument cluster or BCM
4. Blown fuse related to the instrument cluster or reset circuit
5. Software issue or BCM malfunction (rare)

Step-by-Step Diagnostic Guide for B1380 #

A systematic approach ensures you identify the root cause efficiently. Use a digital multimeter and a wiring diagram for your specific vehicle model. Here’s a recommended workflow:

• Confirm the code with an OBD-II scanner and note any additional codes.
• Visually inspect the oil change reset button for damage or sticking.
• Check the wiring harness and connectors between the button and instrument cluster for corrosion, pinched wires, or loose fit.
• Test for continuity and proper voltage at the reset switch using a multimeter.
• Inspect the relevant fuse(s) and replace if blown.
• If no fault is found, perform a function test of the instrument cluster or BCM per OEM service procedures.
• Clear the code and attempt the reset procedure to verify repair.

Possible Repairs for Code B1380 #

Once the root cause is discovered, repairs are generally straightforward. The most effective solutions are:

• Replace the oil change reset button if physically damaged or faulty.
• Repair or replace damaged wiring or corroded connectors in the reset circuit.
• Clean and secure all electrical connections related to the button and cluster.
• Replace blown fuses in the instrument or BCM circuit.
• In rare cases, update or reflash BCM software, or replace BCM if internal failure is confirmed.

Is It Safe to Drive With B1380? #

Yes, you can drive with this code. The B1380 code does not impact the safety or drivability of your vehicle, as it only affects the maintenance reminder system. However, you should address it soon to ensure your oil change schedule is tracked correctly and to avoid confusion at your next service interval.

Vehicles Most Commonly Affected by B1380 #

While this code can appear in various makes, it is more frequently seen in models where the oil change reset is managed by a dedicated button or electronically through the instrument cluster. Examples include:

• Ford F-Series (especially F-150, F-250)
• Chevrolet Silverado and GMC Sierra
• Toyota Camry and Corolla (certain years)
• Honda Accord and Civic
• Jeep Grand Cherokee

Common Mistakes & Best Practices for B1380 #

It’s easy to skip steps or misdiagnose this code, leading to unnecessary parts replacement or recurring issues. Keep these points in mind:

• Don’t replace the instrument cluster or BCM without confirming a hardware fault—most issues are with the switch or wiring.
• Always check for related codes (B-codes, U-codes) that may indicate a broader electrical problem.
• Use the correct wiring diagram for your vehicle’s year and trim.
• After repairs, verify the reset function works before returning the vehicle to service.

Quick FAQ for B1380 #

Need fast answers? Here are two of the top questions about this code:

• Q: Will this code trigger a check engine light?
  A: No, B-codes usually do not illuminate the check engine light but may display a maintenance or service reminder.
• Q: Can I reset the light with a scan tool if the button doesn’t work?
  A: Sometimes, yes. Many professional scan tools offer a maintenance reset function. If the circuit is faulty, however, it may not be successful until repairs are made.
