Severity Level 1 — Low
This code indicates a minor issue that is unlikely to cause immediate driveability problems. You can typically continue driving but should have the vehicle inspected at your earliest convenience.
Common Symptoms
- Power door locks not responding to key fob or interior switch
- Door locks cycling (locking/unlocking) on their own while driving
- Diagnostic trouble code (DTC) stored in module memory
- Fault may be intermittent — code may clear itself and reappear
- Reduced vehicle functionality related to the power door lock/latch system
Possible Causes
- Faulty door lock actuator — most common cause, test before replacing
- Damaged or corroded wiring/connector in the power door lock/latch system circuit
- Blown fuse or faulty relay for the power door lock/latch system
- Poor ground connection — check and clean all related ground points
- Control module fault — rare but possible, only consider after ruling out simpler causes
- Broken wire in the door jamb wiring boot — harness flexes every time the door opens, eventually wires break inside the rubber boot
Common Fixes
- Scan vehicle with a professional-grade OBD2 scanner to read all stored codes and freeze frame data — note the conditions when the code set ($45-118 at shop, free at auto parts store for basic scan)
- Visually inspect the power door lock/latch system wiring harness and connectors — look for chafed wires, melted insulation, green corrosion, loose pins, or rodent damage (often free to check yourself, $80 diagnostic fee at shop)
- Inspect the wiring boot where it passes from the body into the door — this is the #1 failure point. Peel back the rubber boot and check for broken/cracked wires ($0 DIY inspection)
- Replace door lock actuator if testing confirms it has failed — use OEM quality, avoid the cheapest no-name aftermarket parts that fail in a year ($80-500)
- Check and replace any blown fuses in the power door lock/latch system fuse circuit — if fuse blows again, there's still a short that needs to be found ($1-13 for fuses)
