B2325 — Mirror Driver Vertical Feedback Potentiometer Circuit Open #

Please note: The description for this diagnostic trouble code (DTC) may vary depending on the vehicle manufacturer (OEM). Always refer to your vehicle’s service documentation for the most accurate definition.

Known description variations for B2325:

• Mirror Driver Vertical Feedback Potentiometer Circuit Open (General, Ford, GM, Toyota)
• Driver Side Power Mirror Vertical Position Sensor Circuit Open (Nissan)
• Driver’s Mirror Vertical Potentiometer Feedback Malfunction (Honda)

Summary of code B2325 #

B2325 is an OBD-II body code that signals an open circuit in the driver’s side mirror vertical feedback potentiometer. The potentiometer is a sensor that tells the vehicle’s control module the precise angle or position of the mirror in the up/down (vertical) direction. When the circuit is “open,” it means there is a break, disconnection, or high resistance that prevents the sensor from sending information to the mirror control module. As a result, the mirror’s automatic adjustment features may fail or behave unpredictably. This code is most often found in vehicles equipped with power mirrors, memory seat/mirror functions, or advanced driver assistance systems.

Common symptoms for DTC B2325 #

When B2325 is stored, you may notice issues with your driver’s side mirror adjustment. While the car remains drivable, features related to the power mirror may be compromised. Typical symptoms include:

• Driver’s side mirror does not move up/down when using the mirror switch
• Mirror moves in other directions but not vertically
• Memory seat/mirror recall does not position the mirror correctly
• Warning lights or messages related to the mirror system may appear
• Unusual clicking or buzzing noise from the mirror (if the motor tries to move it)

Most likely causes for B2325 #

Several factors can trigger a B2325 code, but some are more common than others. Here are the most probable causes, ranked by frequency:

1. Broken or corroded wiring in the mirror harness, especially at the door hinge area where wires flex
2. Faulty vertical feedback potentiometer (the sensor inside the mirror assembly is defective)
3. Unplugged or loose connector at the mirror or door module
4. Water intrusion causing corrosion at the connector or inside the mirror housing
5. Mirror control module failure (less common)

Step-by-step diagnosis for code B2325 #

Diagnosing B2325 requires a methodical approach to rule out each possible cause. Here’s a recommended procedure:

• 1. Check for other DTCs related to the mirror or door modules—address these first if present.
• 2. Inspect the mirror function: Does the mirror move in any direction? Is the issue only vertical?
• 3. Examine the wiring harness at the door hinge and mirror connector for visible damage, corrosion, or breaks.
• 4. Test the potentiometer circuit using a multimeter: Check for continuity and correct voltage reference at the mirror connector.
• 5. Reconnect or clean connectors as needed.
• 6. Test the potentiometer sensor resistance while moving the mirror manually (if accessible).
• 7. Substitute with a known good mirror assembly to confirm if the fault follows the sensor or remains in the wiring/module.
• 8. Check the mirror control module (if all else passes, consider a software or hardware fault in the module).

Possible repairs for B2325 #

Resolving B2325 generally involves addressing the specific issue found during diagnosis. Depending on the root cause, potential repairs include:

• Repairing or replacing damaged wires between the door and mirror
• Cleaning or reseating electrical connectors at the mirror or door module
• Replacing the driver’s mirror assembly (if the potentiometer is internal and non-serviceable)
• Addressing water intrusion (cleaning and sealing connectors, replacing corroded parts)
• Replacing the mirror control module (rare, only if confirmed faulty after other repairs)

Is it safe to drive with B2325? #

Yes, you can safely drive your vehicle with code B2325 present. This issue affects only the driver’s side mirror vertical adjustment; it does not impact core driving or safety systems. However, you may find it inconvenient if you need to adjust your mirror for visibility or rely on memory mirror features. If the mirror is stuck in a position that impairs your field of view, adjust it manually or have it repaired as soon as possible.

Vehicles most commonly affected by B2325 #

While B2325 can occur in many makes and models with power mirrors, it is most frequently reported in OEM vehicles with advanced mirror or memory features. Some vehicles where this code appears more often include:

• Ford F-Series (F-150, F-250, etc.)
• Chevrolet Silverado, Tahoe, Suburban
• GMC Sierra, Yukon
• Toyota Camry, Avalon, Highlander
• Nissan Altima, Maxima
• Honda Accord, Pilot

Note: This is not an exhaustive list—always verify with your OEM service manual.

Common mistakes & best practices with B2325 #

It’s easy to misdiagnose B2325 if the troubleshooting process is rushed. Here are some common pitfalls and tips to avoid them:

• Replacing the mirror assembly without checking wiring—always inspect the harness at the door hinge for breaks or corrosion first.
• Ignoring connector corrosion—clean all contacts, even if they look clean, as minor oxidation can cause intermittent faults.
• Overlooking related DTCs—address any other codes that may point to module or network communication issues.
• Forgetting to clear codes after repair—always clear the code and test operation to confirm the fix.

Quick FAQ for B2325 #

Q: Can I adjust my mirror manually if B2325 is set?
A: In most cases, yes—you can physically move the mirror glass by hand if the motor isn’t responding, but be gentle to avoid breaking the mechanism.

Q: Does B2325 mean I need a new mirror?
A: Not always. The fault could be due to a wiring or connector issue. Only replace the mirror assembly if the potentiometer (sensor) is confirmed bad or the wiring is intact.
