All Doors Fail To Unlock

Turn the ignition off. Disconnect the remote keyless entry module connector. See Figure. Measure the resistance between ground and the driver door unlock relay output circuit. If the resistance is below 1000 ohms, repair the driver door unlock relay output circuit for a short to ground. If the resistance is above 1000 ohms, the test is complete. Perform BODY VERIFICATION TEST  under VERIFICATION TESTS.
