Power Door Memory Lock Relay Circuit Short To Ground
The power door lock relay circuit has a short to ground, meaning the electrical wire is touching the vehicle's ground somewhere it shouldn't. Think of it like a water hose that has a hole in it—electricity is leaking away instead of powering the door lock system properly.
The ECU monitors the voltage and current draw of the power door memory lock relay circuit. When voltage drops unexpectedly or current exceeds normal operating limits, the ECU detects a short to ground. The system expects a specific resistance range; a short bypasses this and creates abnormally high current flow.
| Parameter | Normal Range | Fault Condition |
|---|---|---|
| Relay Circuit Voltage | 12V-14V when activated | Below 2V or excessive current draw detected |
| Circuit Resistance | 4-8 ohms (typical relay) | Less than 1 ohm indicating short to ground |
Code B1395 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, B1395 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.
