Mirror Passenger Memory Position Error
Your passenger side mirror's memory position system has lost its stored settings, like a broken bookmark that won't remember where you left off. The mirror motor or its control module can't recall the saved position you previously programmed.
The body control module stores mirror position coordinates in memory and compares actual mirror position feedback against stored values when recall is requested. A mismatch between expected and actual position, or failure to communicate with the mirror motor, triggers this fault.
| Parameter | Normal Range | Fault Condition |
|---|---|---|
| Position Feedback Match | Actual position ±5° of stored coordinates | Position deviation >5° or no feedback received |
| Memory Storage Integrity | Data successfully written and read from module | Checksum error or data corruption detected |
Code B2311 is a low-severity fault. Your vehicle is generally safe to drive to a workshop for diagnosis. However, do not ignore it indefinitely — low-severity codes often indicate developing problems that become expensive if neglected. Book a diagnostic appointment within 2–4 weeks. If you notice any additional symptoms (rough running, power loss, unusual smells), treat it as higher priority.
Once the fault is repaired, B2311 can be cleared using any OBD-II scanner. Connect the scanner, navigate to "Clear Codes" or "Erase DTCs," and confirm. The check engine light turns off immediately.
The code will return if the root cause was not actually fixed. The ECM re-detects the fault within 1–3 drive cycles and sets the code again.
