With Scan Tool

PRECAUTIONS FOR OPERATION
(1) When battery voltage is low, no detection of failure is possible. Be sure to check the battery for voltage and other conditions before starting the test.
(2) Diagnosis item is erased if the battery or the ECU connector is disconnected. Do not disconnect the battery before the diagnosis result is completely read.
(3) To diagnose the oxygen sensor, warm up engine and drive a good distance. Do not turn off the ignition switch after driving. If ignition switch is turned off, the result in memory is erased.
(4) After check and correction are over, disconnect ground cable for 10 seconds or more from negative terminal of battery and connect it again to make sure that failure code is erased.
