With Scan Tool

HOW TO DISPLAY AND READ DIAGNOSTIC TROUBLE CODES WITHOUT A SCAN TOOL

NOTE:
1) When battery voltage is low, diagnostic trouble codes can not be read. Be sure to check the battery for voltage and other conditions before starting the test.
2) Diagnosis memory is erased if the battery or the ECM connector is disconnected. Do not disconnect the battery before the diagnostic trouble codes are completely read.




1. Connect the voltmeter to the data link connector.
2. Turn the ignition switch, and the engine control module memory contents will immediately start.

After recording the abnormal item, check and repair each part according to the check items in "Diagnosis Chart".

3. When the defective parts have been repaired, disconnect the negative terminal of the battery cable for 15 seconds or more and connect it again to make sure that the diagnostic trouble code has been erased.
