Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Test B: One Door Lock Inoperative
Disconnect inoperative door lock actuator. Measure voltage between inoperative door lock actuator harness connector terminals while pressing "L" and "U" buttons on door lock switch. Voltage in both positions should be greater than 10 volts. If voltage is greater than 10 volts in both switch positions, replace door lock actuator. If voltage is less than 10 volts, repair open in suspect wire between door lock actuator and door lock relay. See WIRING DIAGRAM .
