Column Reach Motor Stalled
The steering column reach adjustment motor has stopped moving or is not responding to commands, similar to an electric window motor that won't budge. The ECU detected that the motor stalled during an adjustment cycle, meaning it drew too much current without completing its motion.
The ECU monitors motor current draw and position feedback during reach adjustments. It detects a stalled condition when current exceeds threshold for a defined period without reaching target position. The motor is expected to complete travel within a specific time window.
| Parameter | Normal Range | Fault Condition |
|---|---|---|
| Motor Current Draw | 0.5-3.0 Amps during adjustment | >4.0 Amps sustained for >2 seconds |
| Position Feedback | Reaches target position within 5 seconds | No position change detected while stalled current flows |
Code B2340 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, B2340 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.
