Reading Diagnostic Trouble Codes
METHOD OF READING THE DIAGNOSTIC TROUBLE CODESWhen Using the Scan Tool
Connect the scan tool to the data link connector (16-pin) at the lower right of the instrument under cover, and then read the diagnostic trouble codes.
CAUTION: Connection and disconnection of the scan tool should always be carried out with the ignition switch in the OFF position.
When Using a Voltmeter
Connect a voltmeter to (4) terminal and (6) terminal of the data link connector underneath the instrument under cover, and take a reading of the diagnostic trouble codes from the movement of the needle on the voltmeter.
