Mirror Driver Memory Position Error
Your car's side mirror can't remember where you last positioned it, like a broken bookmark that won't save your place. The mirror control module is failing to store or recall the saved mirror position settings.
The body control module (BCM) monitors the mirror motor position sensors and EEPROM memory storage to retain driver-set positions. It compares stored position data against actual mirror position feedback after power-up. A mismatch between stored coordinates and sensor readings triggers this fault.
| Parameter | Normal Range | Fault Condition |
|---|---|---|
| Position Memory Storage | EEPROM data matches sensor feedback within 5 degrees | Stored position deviates >10 degrees from actual sensor position |
| Motor Response Time | Mirror reaches preset in 2-4 seconds | No movement or timeout after 5+ seconds |
Code B2310 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, B2310 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.
