Power Door Lock Control Relay Circuit Testing Charts

NOTE: Power door lock ECU or control relay circuit test charts are provided to pinpoint a malfunctioning circuit. Checking pin voltages at power door lock ECU or control relay connectors will help determine if power door lock ECU and control relay are receiving and sending proper voltage signals. Using test charts may also help determine if there is a short or open in harness or connectors.

NOTE: Unless stated otherwise in testing procedures, perform all voltage tests using a Digital Volt-Ohmmeter (DVOM) with a minimum 10-megohm input impedance. Voltage readings may vary slightly due to battery condition or charging rate.
