CHECK PROCEDURE (SELF-DIAGNOSIS)

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 engine control unit connector is disconnected. Do not disconnect the battery before the diagnosis result is completely read.
(3) 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.




INSPECTION PROCEDURE (Using Voltmeter)
(1) Connect an analog-type voltmeter between the ground terminal and the self-diagnosis output terminal of the diagnosis connector.
(2) Set the ignition switch to the "ON" position.
(3) Make a note of the pattern of the self-diagnosis output indicated by the voltmeter's indicator.
(4) Refer to the diagnosis chart, and repair the indicated location of malfunction.
(5) Erase the malfunction code.
