Typical repair cost: $100 – $600
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
- Battery draining overnight or when vehicle is parked
- Power door locks not responding to controls — stuck in one state
- Door locks cycling (locking/unlocking) on their own while driving
- Excessive current draw on the power door lock/latch system circuit (fuse may blow repeatedly)
Possible Causes
- Damaged wiring in the power door lock/latch system harness shorted to a 12V power source — wiring insulation chafed through from rubbing against metal body panels
- Water intrusion or corrosion in power door lock/latch system electrical connector causing internal short to battery voltage
- Failed door lock actuator — internal short to power within the component
- Aftermarket accessory installation tapped into the wrong circuit, back-feeding 12V
- 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 ($5-142 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, $120 diagnostic fee at shop)
- Repair or replace damaged section of wiring harness where short is located — solder and heat-shrink all connections, don't use crimp connectors on critical circuits ($140-360 depending on accessibility)
- If door lock actuator is internally shorted, replace with a quality OEM or OEM-equivalent aftermarket unit ($80-500)
- Clean all ground points related to the power door lock/latch system — remove bolt, sand contact surface to bare metal, apply dielectric grease, and torque to spec ($54-138 at shop)
