✅Safe to drive — this is an informational or minor issue. Schedule diagnosis at your convenience.

Typical repair cost: $90 – $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

Door locks cycling (locking/unlocking) on their own while driving
Power door locks not working — no response when activated
Power door locks working intermittently, then stopping completely
Infinite resistance in the power door lock/latch circuit — broken wire or disconnected connector

Possible Causes

Broken wire or connector pin in the power door lock/latch system harness — common at flex points like door jambs or where wiring moves
Disconnected or loose electrical connector — may have been bumped during other repairs
Failed door lock actuator — internal open circuit from age, heat cycling, or vibration
Corrosion completely severing a wire or connector terminal — green crust on copper wiring
Wiring harness damage from rodent chewing — look for nesting material near the engine or under dash
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 ($8-108 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, $64 diagnostic fee at shop)
Trace the power door lock/latch system wiring from connector to connector with a multimeter set to continuity/resistance mode — find and repair the break in the circuit ($84-205 labor for diagnosis and repair)
Check and reseat all connectors in the power door lock/latch system circuit — disconnect, inspect pins, clean with electrical contact cleaner, apply dielectric grease, and reconnect firmly ($18 DIY or $62 shop minimum)
If door lock actuator has failed internally (open circuit inside), replace it — don't try to repair sealed components ($80-500)

Estimated Repair Cost

$90 – $600(typical range; varies by vehicle make and model)

These are estimated costs based on generic repair data. Actual costs may vary depending on your vehicle, location, and labor rates.
