B2567 — Reverse Mirror Output Circuit Failure

What is the most common cause of B2567?

The most common causes are: corroded or loose connectors, body control module (BCM) fault, faulty switch, motor or actuator of the affected system.

How do I diagnose B2567 myself?

Start with a scan: confirm B2567, save the freeze frame and note any companion codes. Then inspect the wiring and connectors related to the reverse mirror output circuit, and verify the suspect component against live data before buying parts.

What does OBD2 code B2567 mean?

B2567 — Reverse Mirror Output Circuit Failure. A fault in the body electrical system. The car is usually drivable while you plan the repair. Typical causes: corroded or loose connectors, body control module (BCM) fault, faulty switch, motor or actuator of the affected system.

Will B2567 clear itself?

Sometimes B2567 clears after a few drive cycles if the fault was intermittent — for example a loose connector or a tank of bad fuel. The underlying cause usually remains, so the code tends to return. Clear it once; if it comes back, diagnose rather than erase it repeatedly.

Is it safe to drive with B2567?

Usually safe to drive — body codes rarely affect drivability. Exceptions: exterior lighting and wipers in bad weather, and central locking faults that can leave the car unsecured.

When the powertrain or body control module detects readings that fall outside the manufacturer's acceptable range for the reverse mirror circuit, it logs trouble code B2567. This code specifically points to a Reverse Mirror Output Circuit Failure, which means the electrical pathway responsible for powering or controlling the reverse mirror adjustment has stopped behaving as expected. The affected module runs constant self-checks while the vehicle is running, and once a fault persists long enough across enough drive cycles, it flags B2567 and illuminates the check engine or body control light on your dashboard.

The module that throws B2567 stores more than just the fault code. When it logs this trouble code, it also captures freeze frame data—a snapshot of engine RPM, load, coolant temperature, vehicle speed, and other sensor readings at the exact moment the problem was detected. This snapshot is invaluable during diagnosis because it tells you what conditions existed when the circuit failed. B2567 sits within the body electrical family of codes, meaning the issue lives in the comfort and convenience systems rather than the engine's core operating parameters.

What makes B2567 tricky is that the reverse mirror output touches several other body functions. Depending on your vehicle's architecture, the same circuit or control module might handle mirrors, reverse lights, reverse-activated wipers, or even backup sensors. When that circuit malfunctions, you may lose one function while others work fine, or the problem may come and go depending on temperature, humidity, or road vibration.

Common Symptoms of B2567

The most obvious sign of an active B2567 fault is a warning light glowing on your instrument cluster. Beyond that, drivers typically notice one or more of the following:

• The reverse mirror fails to adjust when you select reverse gear, or adjusts in the wrong direction
• Reverse lights do not illuminate when the transmission is shifted into reverse
• Intermittent or complete loss of the affected electrical function (mirrors, reverse lights, or related systems)
• The problem appears only during cold starts or hot weather, pointing to a temperature-sensitive wiring issue
• No change in engine performance, fuel economy, or throttle response—the fault stays contained within body electronics

What Causes B2567?

Not every case of B2567 stems from the same root cause, and the most affordable fixes should always be investigated before opening your wallet for expensive components. Here are the most common reasons this code appears:

• Corrosion, moisture intrusion, or loose pins inside the electrical connectors feeding the mirror or reverse light circuit
• A faulty body control module (BCM) that cannot properly process or deliver the output signal
• A blown fuse or a relay that has lost its ability to switch under load
• Physical damage to wiring at flex points such as door jambs and tailgate hinges, where repeated motion causes wires to fracture
• A failed mirror adjustment motor, position sensor, or actuator specific to the reverse mirror function
• Aftermarket accessories that create a short or overload condition on the same circuit

How to Diagnose B2567

Proper diagnosis keeps you from throwing parts at the problem. Follow these steps in order:

1. Connect a professional-grade OBD2 scanner, read all stored codes, and capture the freeze frame data associated with B2567. Note the RPM, load, and temperature values—this information reproduces the exact conditions that triggered the fault.
2. Look for any other trouble codes alongside B2567. Codes in the B0xxx range frequently share root causes, and related faults often point directly to the failed component rather than the control module.
3. Check manufacturer technical service bulletins (TSB) for your specific make, model, and model year. Many body electrical codes have documented factory fixes or software updates that a technician can apply at no cost.
4. Perform a hands-on inspection of the wiring harness and connectors in the affected circuit. Pay close attention to areas where wires bend around hinges, door frames, and the tailgate. Look for chafed insulation, green corrosion buildup, and any sign of broken strands inside the wire.
5. Use your scanner's live data function to monitor the mirror motor or reverse light output while commanding the system to activate. If the PID shows no change when you trigger the function, the problem lies upstream in the module or wiring rather than the actuator itself.
6. Clear B2567 after your inspection, then drive the vehicle through a complete drive cycle—include reversing maneuvers under the conditions shown in the freeze frame data. If the code returns, you have confirmed an active hardware fault.

Repair Options and Costs

The repair path depends entirely on what the diagnosis uncovers. Here are typical costs for the most common fixes, covering parts and labor at independent shop rates in the United States:

• Body control module (BCM) repair or replacement: $300–$900 depending on whether the module can be rebuilt or must be replaced with a new or refurbished unit
• Replacement of the faulty switch, mirror motor, actuator, or reverse light bulb housing: $120–$450 depending on the component and vehicle platform
• Wiring repair or connector replacement at flex points: $80–$250 for labor and materials when the damage is localized to a single section of harness

Total Cost to Fix B2567

Expect to spend between $80 and $900 to resolve B2567, depending on which part is actually at fault. The cheapest scenario—repairing a broken wire or cleaning a corroded connector—runs around $80 to $150. Replacing a mirror motor or switch sits in the mid-range at $120 to $450. The most expensive repair, a full BCM replacement, can climb toward $900 when you factor in programming and calibration. A systematic diagnosis before purchasing parts is the single best way to avoid overspending on a problem that started as a loose ground wire.

Driving Safety Verdict

Severity: Short — usually safe to drive short distances with caution. B2567 almost never affects engine performance, braking, or steering, so the vehicle remains mechanically drivable. However, if the fault disables reverse lights, you lose an important safety signal to other drivers when backing up—particularly hazardous at night or in bad weather. A central locking malfunction linked to the same circuit could also leave the car unsecured. Address the underlying cause promptly, and avoid relying on the affected function until it is repaired.
