✅Safe to drive — this is an informational or minor issue. Schedule diagnosis at your convenience.
Typical repair cost: $80 – $500
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 reading abnormally high or staying at maximum
- Door locks cycling (locking/unlocking) on their own while driving
- Engine may run rich or have poor fuel economy (PCM sees faulty signal)
- Diagnostic trouble code (DTC) stored in module memory
Possible Causes
- Failed door lock actuator — internal short causing abnormally high voltage signal to the control module
- Wiring shorted to a 5V reference or 12V power wire in the same harness — wires melted together or chafing at a common point
- Poor ground connection for the power door lock/latch system — high resistance in ground path causes voltage to read high
- Faulty voltage regulator or power supply within the actuator
- 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 ($11-143 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, $149 diagnostic fee at shop)
- Test door lock actuator with a multimeter at the connector — compare readings to factory service manual specs. If out of spec, replace door lock actuator ($80-500)
- Check the reference voltage supply to door lock actuator — should be steady 5V (or 12V) — if low, trace back to PCM/BCM voltage regulator ($142-580 if module repair needed)
- Perform a voltage drop test on the ground side of the power door lock/latch system circuit — more than 0.1V drop means a bad ground that must be cleaned/repaired ($96-289 at shop)
