Seat Horizontal Motor Memory Position Out of Range
The seat's horizontal (forward/backward) motor has moved beyond its expected memory position range, like a garage door opener forgetting where the door should stop. The ECU can't reliably return the seat to your saved position.
The ECU tracks the seat motor's position using potentiometer feedback or encoder signals and compares actual position against stored memory values. When the measured position falls outside the calibrated range (typically 0-100% of full travel), the fault sets. This indicates mechanical binding, motor failure, or loss of position feedback signal.
| Parameter | Normal Range | Fault Condition |
|---|---|---|
| Seat horizontal position feedback | Within ±5% of stored memory position | >5% deviation or signal loss detected |
| Motor position range calibration | 0-100% of full forward/rearward travel | Position reading exceeds calibrated limits |
Code B2167 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, B2167 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.
