What Does B1395 Mean?
This code indicates the Body Control Module (BCM) has detected a short to ground in the power door memory lock relay circuit. The door memory lock system stores and recalls preset driver seat, mirror, and steering wheel positions tied to specific key fobs or driver profiles. The BCM detected abnormally low resistance or voltage in the relay control circuit, indicating current is flowing directly to ground instead of through the intended relay coil.
Common Causes
40%
Damaged wiring harness or chafed wire insulation causing short to ground in relay control circuit
30%
Failed memory lock relay with internal short to ground
20%
Corroded or moisture-damaged BCM connector pins causing ground fault
10%
Failed Body Control Module with internal short in relay driver circuit
Diagnostic Steps
1
Step 1: Perform visual inspection of the memory lock relay location, wiring harness routing through door jambs, and BCM connectors for obvious damage, chafing, water intrusion, or corrosion. Pay special attention to wire pinch points at door hinges.
2
Step 2: Locate and remove the memory lock relay. Using a digital multimeter, measure resistance between the relay control terminals and verify proper coil resistance (typically 70-120 ohms). Test for continuity between relay terminals and ground with relay removed.
3
Step 3: With relay removed and ignition off, measure resistance from the BCM relay control wire (at relay socket) to ground. Reading should be infinite (open circuit). If resistance is below 10k ohms, trace wiring from relay socket to BCM for short location.
4
Step 4: Inspect BCM connector for corrosion, pushed-out pins, or moisture. Disconnect BCM, inspect pins, and measure resistance from relay control pin to BCM ground pins. Infinite resistance indicates external short; low resistance indicates internal BCM fault.
5
Step 5: Repair identified wiring fault or replace failed relay. Reconnect all components, clear codes, and cycle door memory function multiple times while monitoring live data for proper relay operation and voltage readings.
6
Step 6: Road test vehicle and verify door memory functions operate correctly with no code recurrence after multiple key cycles and door memory activations.

The most common cause of B1395 (Power Door Memory Lock Relay Circuit Short To Ground) is: Damaged wiring harness or chafed wire insulation causing short to ground in relay control circuit
Typical repair costs for B1395 range from $100 to $650, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Safe to continue driving. This fault only affects convenience features like power seat/mirror memory positions and does not impact vehicle safety systems or driveability. Repair at earliest convenience to restore memory functions.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to B1395 to identify the root cause.
